Introduction
This section is an introduction to the Debugger from Freescale used in 8/16 bit embedded
applications.
Freescale Debugger
The Debugger is a member of the tool family for Embedded Development. It is a
Multipurpose Tool that you can use for various tasks in the embedded system and
industrial control world. Some typical tasks are:
• Simulation and debugging of an embedded application.
• Simulation and debugging of real-time embedded applications.
• Simulation and/or cross-debugging of an embedded application.
• Multi-Language Debugging: Assembly, C and C++
• True-Time Simulation
• User Components creation with the Peripheral Builder
• Simulation of a hardware design (e.g., board, processor, I/O chip).
• Building a target application using an object oriented approach.
• Building a host application controlling a plant using an object oriented approach.
Debugger Application
A Debugger Application contains the Debugger Engine and a set of debugger components
bound to the task that the components must perform (for example a simulation and
debugging session). The Debugger Engine is the heart of the system. It monitors and
coordinates the tasks of the components. Each Debugger Component has its own
functionality (e.g., source level debugging, profiling, I/O stimulation).
You can adapt your Debugger application to your specific needs. Integrating or removing
the Debugger Components is very easy. You can add additional Debugger Components
(for example, for simulation of a specific I/O peripheral chip) and integrate them with
your Debugger Application.
You can also open several components of the same type.

Debugger Interface
This chapter describes the Debugger Graphical User Interface (GUI). Topics include:
•Introduction
•Application Programs
•Starting the Debugger
•Debugger Main Window
•Component Associated Menus
•Highlights of the User Interface
Introduction
The CodeWarrior™ IDE main window acts as a container for windows of debugger
components. The main window provides a main menu bar, a tool bar, a status bar for
status information, and object information bars for several components.
The Debugger main window allows you to manage the layout of the different component
windows (Window menu of the Debugger application). Component windows are
organized as follows:
• Tiled arrangement - Auto tiled, component windows are automatically resized when
the main window is resized
• Component windows are overlapped
• Component windows that are currently minimized are Debugger Main window
icons.
Application Programs
The CodeWarrior IDE installer places executable programs in the prog subdirectory of
the CodeWarrior IDE installation directory. For example, installing the CodeWarrior IDE
software in C:\Program Files\Freescale, locates all program files in the folder
C:\Program Files\Freescale\CodeWarrior for Microcontrollers
V6.1\prog.

The following list is an overview of files that the CodeWarrior IDE uses for C/C++
debugging:
•hiwave.exe Debugger executable file
•hibase.dll Debugger main function dll
•elfload.dll Debugger loader dll
•*.wnd Debugger component
•*.tgt Debugger target file
•*.cpu Debugger CPU awareness file
Starting the Debugger
This section explains how you can start the debugger from within the CodeWarrior IDE or
from a DOS command line.
Starting from within the IDE
There are two ways to start the debugger from within the IDE, from a Project window
icon, or from the IDE Main Window menu bar.
Starting Debug from the Project Window
To start the debugger from the Project window, click the Debug icon (Figure 2.1), at the
top of the Project window.
Figure 2.1 Project Window Make and Debug Icons

Microcontrollers Debugger Manual
Starting Debug from the Main Window Menu Bar
You can also start the debugger from the main menu bar of the CodeWarrior IDE. To start
the debugger from the main menu bar, select Debug from the Project menu:
(Project > Debug.)
Figure 2.2 Main Window Project Menu
Debugger Command Line Start
You can start the debugger from a DOS command line. The command syntax is as
follows:
HIWAVE.EXE [<AbsFileName> {-<options>}]
where AbsFileName is the name of the application to load in the debugger. Precede
each option with a dash.
![](asset-1e.png)
Debugger Interface
Starting the Debugger
30
Microcontrollers Debugger Manual
Command Line Options
DOS command line options are:
-T=<time>: Test mode
The debugger terminates after the specified time (in seconds). The default value is 300
seconds. For example:
c:\Program Files\Freescale\CodeWarrior for Microcontrollers
V6.1\prog\hiwave.exe -T=10
The above example instructs the debugger to terminate after 10 seconds.
-Target=<targetname>
This option sets the specified connection. For example:
C:\Program Files\Freescale\CodeWarrior for Microcontrollers
V6.1\prog\hiwave.exe c:\Program Files\Freescale\CodeWarrior
for Microcontrollers V6.1\demo\hc12\sim\fibo.abs -w
-
Target=sim
The command in the above example starts the debugger and loads fibo.abs file.
-W: Wait mode
Debugger waits even when a <exeName> is specified.
-Instance=%currentTargetName
This option defines a build instance name. Once you define a build instance, the debugger
uses same build instance the next time you start the debugger. For example:
c:\Program Files\Freescale\CodeWarrior for Microcontrollers
V6.1\prog\hiwave.exe
-Instance=%currentTargetName
If you attempt to start the debugger again, the existing instance of the debugger is brought
to the foreground.
-Prod= <fileName>
This option specifies the project directory and/or project file to be used at start-up. For
example:
c:\Program Files\Freescale\CodeWarrior for Microcontrollers
V6.1\prog\hiwave.exe
-Prod=c:\demoproject\test.pjt
![](asset-1f.png)
Debugger Interface
Starting the Debugger
31
Microcontrollers Debugger Manual
-Nodefaults
This prevents the debugger from loading the default layout. For example:
c:\Program Files\Freescale\CodeWarrior for Microcontrollers
V6.1\prog\hiwave.exe
-nodefaults
-Cmd = <Command>
This option specifies a command to be executed at start-up: -cmd = {command}. For
example:
c:\Program Files\Freescale\CodeWarrior for Microcontrollers
V6.1\prog\hiwave.exe -cmd="open recorder"
-C <cmdFile>
This option specifies a command file to be executed at start-up. For example:
c:\Program Files\Freescale\CodeWarrior for Microcontrollers
V6.1\prog\hiwave.exe -c c:\temp\mycommandfile.txt
-ENVpath: "-Env" <Environment Variable> "=" <Variable
Setting>
This option sets an environment variable. This environment variable may be used to
overwrite system environment variables. For example:
c:\Program Files\Freescale\CodeWarrior for Microcontrollers
V6.1\prog\hiwave.exe -EnvOBJPATH=c:\sources\obj
NOTE Options are not case sensitive.
Order of Commands
Commands specified by options are executed in the following order:
1. Load (activate) the project file (see below). If the project file is not specified,
project.ini is used by default.
2. Load <exeFile> if available and start running unless option |(W) was specified
3. Execute command file <cmdFile> if specified
4. Execute command if specified
5. Start running unless option |(W) was specified
NOTE In version 6.1 of the debugger, the loaded program starts after all command and
command files are executed.

Menu entry Description
Start/Continue Starts or continues execution of the loaded application from the
current program counter (PC) until a breakpoint or watchpoint is
reached, runtime error is detected, or user stops the application by
selecting
Run > Halt
.
Shortcut: F5 key
Restart Starts execution of the loaded application from its entry point.
Shortcut: CTRL + Shift + F5 keys
Halt Interrupts and halts a running application. You can examine the state
of each variable in the application, set breakpoints, watchpoints, and
inspect source code.
Shortcut: F6 key
Single Step If the application is halted, this command performs a single step at the
source level. Execution continues until the next source reference is
reached. If the current statement is a procedure call, the debugger
“steps into” that procedure. The Single Step command does not treat
a function call as one statement, therefore it steps into the function.
Shortcut: F11 key
Step Over Similar to the Single Step command, but does not step into called
functions. A function call is treated as one statement.
Shortcut: F10 key
Step Out If the application is halted inside of a function, this command continues
execution and then stops at the instruction following the current
function invocation. If no function calls are present, then the Step Out
command is not performed.
Shortcut: Shift + F11 keys
Assembly
Step
If the application is halted, this command performs a single step at the
assembly level. Execution continues for one CPU instruction from the
point it was halted. This command is similar to the Single Step
command, but executes one machine instruction rather than a high
level language statement.
Shortcut: CTRL + F11 keys
![](asset-2b.png)
Debugger Interface

instructions.
Shortcut: CRTL + F10 keys
Assembly
Step Out
If the application is halted inside a function, this command continues
execution and stops on the CPU instruction following the current
function invocation. This command is similar to the Step Out
command, but stops before the assignment of the result from the
function call.

Debugger Components
This chapter explains how the different components of the Debugger work. This chapter
contains the following sections:
•Component Introduction
•Loading Component Windows
•General Debugger Components
•Visualization Utilities
Component Introduction
The Debugger kernel includes various components.
CPU Components
CPU components handle processor-specific properties such as register naming, instruction
decoding (disassembling), and stack tracing. A specific implementation of the CPU
module must be provided for each processor type that is supported in the debugger. The
CPU-related component is not introduced in this section. However, the Register
component, Memory component, and all other Connection-dependent components reflect
this system component. The appropriate CPU component loads automatically when
loading an application or executable file (.ABS file), therefore it is possible to mix
applications for different MCUs. The Debugger automatically detects the MCU type and
loads the appropriate CPU component, if available on your environment.
Window Components
The Debugger main window components are small applications loaded into the debugger
framework at run-time. Window components can access all global facilities of the
debugger engine, such as the connection (to communicate with different connections), and
the symbol table. The Debugger window components are implemented as dynamic link
libraries (DLLs) with extension .WND. These components are introduced in this section.
![](asset-3e.png)
Debugger Components
Component Introduction
62
Microcontrollers Debugger Manual
Connection Components
Different debugger connections are available. For example, you can set a CPU awareness
to simulate your .ABS application files, and also set a background debugger.
Different connections are available to connect the target system (hardware) to the
debugger. For example, the connection may be connected using a Full Chip Simulator, an
Emulator, a ROM monitor, a BDM pod cable, or any other supported device.
NOTE Connection components are introduced in their respective manuals.
Loading Component Windows
In the Debugger Main Window Menu Bar, shown in Figure 3.1, you can use the
Component menu to load all framework components. Each Debugger component you
select appears as a window in the Debugger main window.
Figure 3.1 Debugger Window Menu Bar
To open the window that lets you choose one or more components:
1. Choose Component > Open
2. In the Open Window Component window shown in Figure 3.2, select the desired
component.
NOTE To open more than one component, select multiple components.

General Debugger Components
This section describes the various features and usage of the debugger components.
Assembly Component
The Assembly window, shown in Figure 3.3, displays program code in disassembled
form. It has a function very similar to that of the Source component window but on a much
lower abstraction level. Thus it is therefore possible to view, change, monitor and control
the current location of execution in a program.
Figure 3.3 Assembly Window
This window contains all on-line disassembled instructions generated by the loaded
application. Each displayed disassembled line in the window can show the following
information: the address, machine code, instruction and absolute address in case of a
branch instruction. By default, the user can see the instruction and absolute address.
If breakpoints have been set in the application, they are marked in the Assembly
component with a special symbol, depending on the kind of breakpoint.
If execution has stopped, the current position is marked in the Assembly component by
highlighting the corresponding instruction.
The Object Info Bar of the component window contains the procedure name, which
contains the currently selected instruction. When a procedure is double clicked in the
Procedure component, the current assembly statement inside this procedure is highlighted
in the Assembly component.

TIP HCS08 devices with Memory Management Unit (MMU) have two address spaces.
The Paged address space covers regular, that is, physical/local and logical displays
(see Banked/Window Paged Memory: Physical/Local vs. Logical display for
further details). The Flash address space covers the Extended Address range
(covering the Flash memory as one single linear range), as accessed by the Linear

Microcontrollers Debugger Manual
Banked/Window Paged Memory: Physical/Local
vs. Logical display
This section applies only to devices having on-chip program pages or data pages. For
Legacy reasons, the debugger provides two ways to display the banked/window paged
memory, such as the PPAGE window $8000-$BFFF range with HCS08 devices with on-
chip MMU, or EEPROM windows bit selectable:
• The default display is called the physical display in the Debugging Memory Map
(DMM) interface. It is sometimes called the local display in device specifications
and matches exactly what the CPU “sees” for silicon memory. This means that what
is displayed in the Memory window at a specific suspended time (debugger halted)
matches the current setup of Page registers (like PPAGE) or selection bit like
EPGSEL for EEPROM, etc. Changing the page registers or selection bit and then
refreshing the Memory window immediately shows changes in the window range.
• The logical display gives a constant Memory view at a specific address. For example,
if we define, in a window address range, the concatenation of PPAGE<<16 added
with the physical/local address, we obtain a 24-bit address that does not represent
anything for the CPU, but that is directly readable by the user in the Memory
window.
By default, for 8/16-bit devices, the debugger displays memory addresses above address
0xFFFF as logical. These addresses do not represent actual addresses anymore, but are
still required by the debugger to synchronize the program flow display and data accesses
within all windows.
The debugger defines page range accessibility in the DMM interface. Also, for 8/16-bit
devices, in the physical/local $0000-$FFFF, the window ranges can be also defined as
logical in the DMM interface, to make them constant at display. For example, the range
$8000-$BFFF program window can be changed from physical to paged (also EEPROM
paged for paged EEPROM) in the DMM graphical user interface, and the debugger no
longer displays what the CPU “sees”, but always displays PPAGE $00 when looking at
addresses in the $008000-$00BFFF range.
The debugger provides by default a mixed display, that can be quickly changed when
editing the module setup in the DMM interface. Refer to Debugging Memory Map for
further details.
Memory Operations
• Double-click a memory position to edit it. If the memory is not initialized, this
operation is not possible.
• Drag the mouse in the memory dump to select a memory range.

Microcontrollers Debugger Manual
• Hold down the left mouse button + A key to jump to a memory address. The pointed
to value is interpreted as an address and the memory component dumps memory
starting at this address.
• Select a memory range, and hold down the left mouse button + R key to set a Read
watchpoint for the selected memory area. Memory ranges where a read watchpoint
has been defined are underlined in green. If read access on the memory area is
detected during execution, the program is halted and the current program state is
displayed in all window components.
• Select a memory range, and hold down the left mouse button + W key to set a Write
watchpoint on the selected memory area. Memory ranges where a write watchpoint
has been defined are underlined in red. If write access on the memory area is detected
during execution, the program is halted and the current program state is displayed in
all window components.
• Select a memory range, and hold down the left mouse button + B key to set a Read/
Write watchpoint on the selected memory area. Memory ranges where a read/write
watchpoint has been defined are underlined in black. If the memory area is exceeded
during execution, the program is halted and the current program state is displayed in
all window components.
• Select a memory range on which a watchpoint was previously defined, and hold
down the left mouse button + D key to delete the watchpoint on the selected memory
area. The memory area is no longer underlined.
• Select a memory range, and hold down the left mouse button + S key to set a
watchpoint on the selected memory area. The Watchpoints Setting dialog box is
opened. Memory ranges where a watchpoint has been defined are underlined in
black.

You can use a virtual SCI (Serial Communication Interface) port provided by the
framework for communication with the target, but it is also possible to use the keyboard,
the display, some files or even the serial port of your computer as I/O-devices.
To control and configure a terminal component use the Terminal menu of the terminal
shown in Figure 3.70.
Figure 3.70 Terminal Menu and Context Menu
To open the context menu, right click in the terminal window.
Configure Terminal Connections
The terminal window is very flexible and can redirect characters received from any
available input device to any available output device. You can specify these connections
by choosing Configure Connections in the context menu of the terminal component. This
opens the dialog box shown in Figure 3.71.
Figure 3.71 Configure Terminal Connections Dialog Box
![](asset-7f.png)
Debugger Components
General Debugger Components
127
Microcontrollers Debugger Manual
You can simply choose one of the default configurations in the Default Configuration
combo box. In the Connections section all active connections are listed in a list box.
There you can customize input to output device redirection by adding and removing
connections.
To add a connection specify the source and target devices using the From and To combo
boxes and then press the Add button. The new connection then appears in the list below,
which shows all active connections.
To remove connections, select them in the list of active connections and press the Remove
button.
In the Serial Port section you can specify which serial port to use and its properties. This
is only possible if there is at least one connection from or to the serial port.
If you select a connection from or to the virtual SCI port you can also specify which ports
to take as virtual SCI ports in the Virtual SCI section. This enables you to make a
connection to any port in the FCS framework.
Input and Output File
It is also possible to take a file as an input stream for the terminal component or redirect
the output to a file.
To use a file as an input stream, make sure that there exists at least one connection from
the input file to any output device. Then you can open an input file by simply choosing
Input File from the context menu. As soon as you press the OK button in the File Open
dialog, input from the file starts. The file closes as soon as the end of file is reached or you
choose Close Input File from the context menu.
When the input file has reached its end, it sends a CTRL-Z character (ASCII code 26
decimal) to all output devices receiving characters from the input file to notify them that
the file transfer has been finished.
If you want to redirect some input devices to an output file, you have to proceed similarly.
Make sure that you have chosen your connections from input devices to the output file.
Then you can open or create your output file by choosing Output File from the context
menu. If the file does not exist it is created. Otherwise you can choose to overwrite or
append the existing file. To stop writing to the output file you can choose Close Output
File from the context menu.
File Control Commands
It is also possible to open and close input and output files through special Escape
sequences in the data stream from serial port or virtual SCI. Table 3.37 illustrates the
different possible commands and associated Escape sequences where filename is a
sequence of characters terminated by a control character (e.g. CR) and is a valid filename.
![](asset-80.png)
Debugger Components
General Debugger Components
128
Microcontrollers Debugger Manual
ESC is the ESC Character (ASCII code 27 decimal).
These commands can be given in the data stream sent from the serial port or virtual SCI
port, but not from the input file or the keyboard. They only have an effect if there are any
connections reading from the input file or writing to the output file.
The TERM_Direct function declared in terminal.h is used to send such commands
from a target via SCI to the terminal. Listing 3.3 shows the source code in terminal.c.
Listing 3.3 TERM_Direct Source Code
void TERM_Direct(TERM_DirectKind what, const char* fileName) {
/* sets direction of the terminal */
if (what < TERM_TO_WINDOW || what > TERM_APPEND_FILE) return;
TERM_Write(ESC); TERM_Write('h');
TERM_Write((char)(what + '0'));
if (what != TERM_TO_WINDOW && what != TERM_FROM_KEYS) {
TERM_WriteString(fileName); TERM_Write(CR);
}
}
In the example, the parameter what is one of the following constants:
•TERM_TO_WINDOW: send output to terminal window
•TERM_TO_BOTH: send output to file and window
•TERM_TO_FILE: send output to file fileName
•TERM_FROM_KEYS: read from keyboard (close input file)
•TERM_FROM_FILE: read input from file fileName
Table 3.37 Terminal File Control Commands

•TERM_APPEND_BOTH: append output to file and window
•TERM_APPEND_FILE: append output to file fileName
See also terminal.h for further details.
How to Use Virtual SCI
In its default Virtual SCI configuration the terminal component accesses the target
through the Object Pool interface.
To make the terminal component work in this default configuration, the target must
provide an object with the name Sci0. If no Sci0 object is available, no input or output
happens. It is possible to check, through the Inspector component, if the environment
currently provides an Sci0 object.
NOTE Only some specific Full Chip Simulation components currently have a Sci0
object. For all other Full Chip Simulation components the default virtual SCI
port does not work unless a user defined Sci0 object with the specified register
name is loaded.
Write access to the target application is done with the Object Pool function OP_SetValue
at the address Sci0.SerialInput.
Input from the target application is handled with a subscription to an Object Pool register
with the name Sci0.SerialOutput. When this register changes (sends a notification), a

For implementations of this register with help of the IOBase class, use the

Visualization Utilities
Besides components that provide the Debugger engine a well-defined service dedicated to
the task of application development, the debugger component family includes utility
components that extend to the productive phase of applications, such as, the host
application builder components, process visualization components, etc.
Among these components, there are visualization utilities that graphically display values,
registers, memory cells, etc., or provide an advanced graphical user interface to simulated
I/O devices, program variables, and so forth.
The following components of the continuously growing set of visualization utilities
belong to the standard Debugger installation.
Inspector Component
The Inspector window shown in Figure 3.77 displays information about several topics. It
displays loaded components, the visible stack, pending events, pending exceptions and
loaded I/O devices.
Figure 3.77 Inspector Component Window
The hierarchical content of the items is displayed in a tree structure. If any item is selected
on the left side, then additional information is displayed on the right side.

Microcontrollers Debugger Manual
In the figure above, for example, the Object Pool is expanded. The Object Pool contains
the TargetObject, which contains the Leds and Swap peripheral devices. The Swap
peripheral device is selected and registers of the Swap device are displayed.
Components Icon
When the components icon is selected in the Inspect window, as shown in Figure 3.78, the
right side displays various information about all loaded components. A Component is the
“unit of dynamic loading”, therefore all windows, the CPU, the connection and perhaps
the connection-simulator are listed.
Figure 3.78 Inspect Window Components Icon
Stack Icon
The Stack icon shown in Figure 3.79 displays the current stack trace. Every function on
the stack has a separate icon on the trace. In the stack-trace, the content of a local variable
is accessible.

Symbol Table
The symbol table shown in Figure 3.80 displays all loaded symbol table information in
raw format. There are no stack frames associated with functions. Therefore the content of
local variables is not displayed. Global variables and their types are displayed.
Figure 3.80 Inspector Window Symbol Table
Events Icon
The Inspect window Events icon shown in Figure 3.81 shows all currently installed
events. Events are handled by peripheral devices, and notified at a given time. The Event
display shows the name of the event and remaining time until the event occurs.
Figure 3.81 Inspector Window Events Icon
Events are only used in the HC(S)08 Freescale Full Chip Simulator. This information is
used for simulation I/O device development.
When simulating a watchdog/COP, an event with the remaining time is displayed in the
Event View.
Exceptions Icon
The Inspector window Exceptions icon shown in Figure 3.82 shows all currently raised
exceptions. Exceptions are pending interrupts.
![](asset-88.png)

Microcontrollers Debugger Manual
Figure 3.82 Inspector Window Exceptions Icon
Events are only used in the HC(S)08 Freescale Full Chip Simulator. This information is
used for simulation I/O device development.
Since interrupts are usually simulated immediately when they are raised, the Exceptions
are usually empty. Only when interrupts are disabled or an interrupt is handled, something
is visible in this item.
When simulating a watchdog/COP, an Exception is raised as soon as the watchdog time
elapses.
Object Pool
The Object Pool shown in Figure 3.83 is a pool of objects. It can contain any number of
Objects, which can communicate together and also with other parts of the Debugger.
Figure 3.83 Inspector Window Object Pool
The most common use of Objects is to simulate special hardware with the I/O
development package, however, other connections also use the Object Pool. For example,
the Terminal Component exchanges its input and output by the Object Pool. The Terminal
Component also operates with some hardware connections.
For the HC(S)08 Freescale Full Chip Simulator, the Object Pool usually contains the
TargetObject, which represents the address space. All Objects that are loaded are
displayed in the Object Pool. The TargetObject additionally shows the objects that are
mapped to the address space.

IO Registers
The IO Registers icon shown in Figure 3.84 shows all the IO Registers and Core Registers
referenced by the debugger database. The Inspector can therefore provide many more
registers information than the regular Register window.
Figure 3.84 Inspector Window IO Registers: ColdFire registers set example
Each group of registers can be expanded, and registers can be directly edited in the Value
column when double-clicking directly on the value. Register names are provided in the
Name column, an access result diagnostic is given in the AccessResult column, the
register size is given in bits in the size column, the kind of access (read, read/write, write is
given in the Access column, and finally the Type column indicates if the register is
memory mapped or is a special purpose register (core).
Inspector Operations
Click the folded/unfolded icons to unfold/fold the tree and display/hide additional
information.
Click on any icon or name to see the corresponding information displayed on the right

Visualization Tool Component
The Visualization Tool component is a very convenient tool for presenting your data. For
software demonstration, or for your own debugging session, take advantage of all its
virtual instruments.
The VisualizationTool window, shown in Figure 3.88, consists of a plain workspace that
can be equipped with many different instruments.
Figure 3.88 VisualizationTool Window
Edit Mode and Display Mode
The VisualizationTool may operate in two modes: Display mode or Edit mode.
The Edit mode is for designing the workspace to suit your needs. In the Display mode you
can then use what you have done in the Edit mode, that is, to view values, interact with
your application and instruments, press buttons, etc.
To switch between these two modes, you can use the toolbar, the context menu, or the
shortcut Ctrl+E.

You can select a single instrument by left clicking the mouse on it, and change the
selection by pressing the tab-key.
To make multiple selections, hold down the control key and left-click on the desired
instruments. You can also left click, hold and move to create a selection rectangle.
Move Instruments
There are two ways to move instruments. First, make your desired selection. You can then
use the mouse to drag the instruments, or use the cursor keys to move them step by step
(hold down the control key to move the instrument in steps of ten). The move process
performed with the mouse can be broken off by pressing the escape key.
Resize Instruments
When you select a instrument, sizing handles appear at the corners and along the edges of
the selection rectangle. You can resize an object by dragging its sizing handles, or by
using the cursor keys while holding down the shift key. The resize process performed with
the mouse can be broken off by pressing the escape key. Only one instrument can be
resized at a time. Furthermore, each instruments has its own size minimum.

In general, for showing the bitmap, the following condition has to be true:
(port_memory & ANDmask) == EQUALmask
Following is a practical example about using the AND and EQUAL masks
You want to show in the visualization a tail light of a car. For this you need bitmaps (e.g.
from a digital camera) of all possible states of the tail light (e.g. flasher on, brake light on,
etc.). Usually the status of all lamps are encoded into a port or memory cell in your
application, and each bit in this cell describes whether a lamp is on (e.g., bit 0 says that the

contains the address of the variable. Now repeat the drag-and-drop on a bare portion of the
VisualizationTool window: a new text instrument is created, with correct port
configuration.
Some other components allow this operation:
• The memory window: select bytes and drag-and-drop them onto the instrument.
• The Inspector component: pick an object from the object pool.

Control Points
This chapter provides an overview of the debugger control points: Breakpoints,
Watchpoints, and Markpoints. Click any of the following links to jump to the
corresponding section of this chapter:

Introduction
There are three kinds of control points:
• Breakpoints (also called data breakpoints): Breakpoints are located at an address.
They can be temporary or permanent.
• Watchpoints: Watchpoints are located at a memory range. They start from an
address, have a range, and a read and/or write state.
• Markpoints: Are marked points of observation that can be jumped to by the
programmer. They can be located in data, source or memory.
In the context menu of the Source, Memory or Assembly window you can set or disable a
control point, set a condition and an optional command, and set the current count and
counting interval.
You can edit control point characteristics in the three tabs of the Control Points
Configuration Window: Breakpoints, Watchpoints and Markpoints tab. These three tabs
have common properties that allow you to perform the following operations on control
points:
• Select a single control point from a list box and click Delete.
• Select multiple control points from a list box and click Delete.

• Enable/disable the command of a selected control point by checking/unchecking the
related checkbox.
• Enable/disable multiple control point commands by selecting control points and
checking/unchecking the related checkbox.
• Modify the counter and/or limit of a single control point.
With breakpoints, the following operations are also available:
• Enable/disable halting on a single temporary breakpoint by checking/unchecking the
matching checkbox.
• Enable/disable halting on multiple temporary breakpoints by checking/unchecking
the matching checkbox.
With watchpoints, the following operations are also available:
• Enable/disable halting on a single read and/or write access by checking/unchecking
the corresponding checkboxes.
• Enable/disable halting on multiple read and/or write accesses by checking/
unchecking the corresponding checkboxes.
• Define the memory range controlled by the watchpoint.
Breakpoints
Breakpoints are control points associated with a PC value. That is, program execution is
stopped as soon as the PC reaches the value defined in a breakpoint. The debugger
supports four different types of breakpoints:
• Temporary breakpoints, which are activated next time the instruction is executed.
• Permanent breakpoints, which are activated each time the instruction is executed.
• Counting breakpoints, which are activated after the instruction has been executed a
certain number of times.
• Conditional breakpoints, which are activated when a given condition is TRUE.

Microcontrollers Debugger Manual
Saving Breakpoints
The Debugger provides a way to store all defined breakpoints of the currently loaded
application (.ABS file) into the matching breakpoints file. The matching file has the
same name as the loaded .ABS file but its extension is .BPT (for example, the
FIBO.ABS file has a breakpoint file called FIBO.BPT). This file is generated in the
same directory as the .ABS file. This is a text file, in which a sequence of commands is
stored. This file contains the following information.
•The Save & Restore on load flag (Save & Restore on load checkbox in the
Controlpoints Configuration Window (Breakpoints Tab)). The SAVEBP command
is used: SAVEBP on when checked, SAVEBP off when unchecked.
NOTE For more information about this, see the SAVEBP command.
• List of defined breakpoints: the BS command is used, as shown in Listing 4.1.
Listing 4.1 Breakpoint (.BPT) File Syntax
BS address [P|T[ state]][;cond=”condition”[ state]]
[;cmd=”command”[ state]][;cur=current[ inter=interval]]
[;cdSz=codeSize[ srSz=sourceSize]]
In the code above:
The address value is the address where the breakpoint is to be set. This address is
specified in ANSI C format. The address value can also be replaced by an expression as
shown in the example below.
P specifies the breakpoint as a permanent breakpoint.
T specifies the breakpoint as a temporary breakpoint. A temporary breakpoint is deleted
once it is reached.
The state is E, D or C where E is for enabled (state is set by default to E if nothing is
specified), D is for disabled and C for Continue.
The condition is an expression. It matches the Condition field in the Controlpoints
Configuration Window (Breakpoints Tab) for conditional breakpoint.
The command is any debugger command. It matches the Command field in the
Controlpoints Configuration Window (Breakpoints Tab), for associated commands.
The current value is an expression. It matches the Current field (Counter) in the
Controlpoints Configuration Window (Breakpoints Tab), for counting breakpoints.
The interval is an expression. It matches the Interval field (Counter) in the
Controlpoints Configuration Window (Breakpoints Tab), for counting breakpoints.
![](asset-a3.png)

Microcontrollers Debugger Manual
The codeSize value is an expression. It is usually a constant number to specify (for
security) the code size of a function where a breakpoint is set. If the size specified does not
match the size of the function currently loaded in the .ABS file, the breakpoint is set but it
is disabled.
The sourceSize value is an expression. It is usually a constant number to specify (for
security) the source (text) size of a function where a breakpoint is set. If the size specified
does not match the size of the function in the source file, the breakpoint is set but it is
disabled.
• If Save & Restore on load is checked and the user quits the debugger or loads
another .ABS file, all breakpoints are saved.
• If Save & Restore on load is clear (default), only this flag (SAVEBP off) is saved.
Breakpoint File (.BPT) Example
Case 1: If FIBO.ABS is loaded, and Save & Restore on load was checked in a previous
session of the same .ABS file, and breakpoints have been defined, the FIBO.BPT looks
as shown in Listing 4.2.
Listing 4.2 Breakpoint File with Save & Restore on load Checked
savebp on
BS &fibo.c:Fibonacci+19 P E; cond = "fibo > 10" E; cdSz = 47 srSz = 0
BS &fibo.c:Fibonacci+31 P E; cdSz = 47 srSz = 0
BS &fibo.c:main+12 P E; cdSz = 42 srSz = 0
BS &fibo.c:main+21 P E; cond = "fiboCount==5" E; cmd = "Assembly < spc
0x800" E; cdSz = 42 srSz = 0
Case 2: If FIBO.ABS is loaded, and Save & Restore on load was unchecked in a
previous session of the same.ABS file and breakpoints have been defined, the FIBO.BPT
looks as shown below:
savebp on
Only the flag has been saved and breakpoints have been removed.
NOTE If only one or few functions differ after a recompile, not all breakpoints are
lost. Breakpoints are disabled only if the size of a function changes. The size of
a function is evaluated in bytes (when it is compiled) and in characters (number
of characters contained in the function source text). When an .ABS file is
loaded and the matching .BPT file exists, for each BS command, the debugger
checks if the code size (in bytes) and the source size (in characters) are
different in the matching function (given by the symbol table). If there is a
difference, the debugger sets and disables the breakpoint. If there is no
difference, the debugger sets and enables the breakpoint.

Real Time Kernel
Awareness
The Debugger allows you to load and control applications on the target system, or
applications simulated on the host. It also allows you to inspect the state of the application,
which includes global variables, processor registers and the procedure call chain including
the local (automatic) variables.
This chapter describes how applications built of several tasks are handled by a generic
awareness support and an OSEK awareness.
Topics in this chapter include:
•Introduction
•Task Description Language
•Application Example
•Inspecting Kernel Data Structures
•OSEK Kernel Awareness
Introduction
Often operating systems (Real Time Kernels) are used to coordinate the different tasks in
more complex systems. This chapter describes how applications built of several tasks can
be handled with the Debugger. There are two main topics to be considered:
• Debugging of any task in the system (e.g., viewing the state of any task in the
system). When using the original basic versions of the Debugger, only the current
task can be inspected. Due to this extension, it is possible to switch the debugging
context from the current task to any other task in the system.
• Real time kernels use data structures to describe the state of the system (scheduling
information, queues, timers, etc.). Some of these data structures are described in this
chapter.
![](asset-ba.png)
Real Time Kernel Awareness
Task Description Language
186
Microcontrollers Debugger Manual
Inspecting Task State
Each multitasking operating system stores the context of each task at a specific location,
usually called the task descriptor. This context consists of the CPU context (CPU
registers) and the content of the associated stack. There is more information in the task
descriptor, depending on the specific implementation of the kernel.
The Debugger allows you to inspect the CPU registers and stack containing all procedure
activation frames (return addresses, parameters, local variables). Therefore, it has to get
this information for each task to be debugged. Since this information is specific to the
kernel used, there is a universal way to specify the location where and how to collect this
data.
This information is read from a file with the name OSPARAM.PRM, which describes the
algorithm of how to get all the needed data from the target memory (from the task
descriptors). To describe this algorithm, a simple procedural language is used. The only
parameter to the algorithm is an address specified by the user, which identifies the task to
be inspected. The result is the CPU context (CPU registers) and status of the task, which
allows the debugger to display the procedure activation stack in a symbolic way.
RTK Interface
When the application is halted, the debugger displays the state of the current task. To
identify the task to be inspected, the user has to follow these steps.
Make the task descriptor or a pointer to it visible in any of the debugger's data windows.
Press the P key while holding down the left mouse button on a variable of type "pointer to
task descriptor".
Now the current state of the selected task and procedure chain of that task is displayed in
the 'Procedure Chain' window. By clicking on the procedures in the call chain list, the
local data of that function is displayed in the Data1 window. All the usual debugging
functions are also available to inspect this task (including displaying the register contents).
Task Description Language
To debug a task, a file named OSPARAM.PRM has to be created and must be stored in one
of the directories specified in GENPATH: #include “File” Path.
The file OSPARAM.PRM describes the algorithm to collect the context information for a
specific task (the PC, SP, DL, SR and registers).
The following syntax must be used to specify the algorithm (in EBNF):
StatSequence = Statement] {';' Statement;}.
Statement = Assignment | ErrorMsg | If.
![](asset-bb.png)
Real Time Kernel Awareness
Task Description Language
187
Microcontrollers Debugger Manual
Assignment = Ident ':=' Expression.
ErrorMsg = 'MSG' ':=' String.
IfStatemen = 'IF' BoolExpr 'THEN' StatSequence {ELSIFPart} [ELSEPart]
'END'.
ELSIFPart = 'ELSIF' BoolExpr 'THEN' StatSequence.
ELSEPart = 'ELSE' StatSequence.
String = '"' {char} '"'.
BoolExpr = Expression RelOp Expression.
Expression = Term {Op Term}.
Term = Ident | Function | Number.
Ident = 'a'..'z' | 'R00'..'R31' | 'DL' | 'SP' | 'SR' | 'PC' | 'STATUS'
| 'B'.
Function = ('MB' | 'MW' | 'MD' | 'MA') '[' Expression ']'.
RelOp = '#' | '<' | '<=' | '=' | '>=' | '>'.
Op = '+' | '-'.
The terminal symbols have the following meaning:
• B – is the given reference to the task descriptor (initialized upon start).
• a–z – are variables for intermediate storage.
• MB – gets value of memory BYTE at given address.
• MW – gets value of memory WORD at given address.
• MD – gets value of DOUBLE WORD at given address.
• MA – gets value at given address interpreted as DOUBLE WORD.
• PC – is the program counter to be set.
• SP – is the stack pointer to be set.
• SR – is the status register value to be set.
• DL – is the dynamic link (data base) to be set (if not available, same as SP).
• STATUS – is the error number to be set (refer to manual).
• Rnn – processor registers to be set (mapping to CPU registers; see manual).
• MSG – is the error message (must be specified if N >= 1000).
On activation of the task debugging command, the file OSPARAM.PRM is opened and the
selected address is stored in variable 'B'. Then the commands in the file are interpreted.
The CPU context of the task is then expected in the variables PC, SP, SR, DL, Rnn and
EN. EN describes the status of the task. If 'EN' is bigger than 1000 the status is expected in
the string MSG.

Inspecting Kernel Data Structures
189
Microcontrollers Debugger Manual
Inspecting Kernel Data Structures
To allow the debugger to display the data structures of the operating system, the
corresponding symbol information has to be available. This is the case when using SOOM
System/REM. When another kernel is used its source code must to be available and must
be compiled. However, if only the object code is available, the needed symbol information
can be generated in the following way:
• The kernel data structures of interest must be described using ANSI-C language, as
shown in Listing 5.2.
Listing 5.2 Kernel Data Structure Description
typedef struct PD {
int status;
struct PD *next;
long regs[6];
} PD;
This is an example of the definition of a simple task descriptor.
• Variables can be collected in a structure and must be assigned to a segment (for
example, OS_DATA shown in Listing 5.3).
Listing 5.3 OS_DATA Structure
#pragma DATA_SEG OS_DATA
struct {
PD *readyList; /* list of tasks ready to be executed */
char filler[6]; /* unimportant variables */
int processes; /* total number of tasks */
PD processes[10]; /* the 10 possible tasks */
} OS_DATA;
Define this structure so that it fits the same layout as the operating system. It might be
necessary to introduce filler variables to get the correct alignment.
The linker must place this segment to the correct address by using the PRM file shown in
Listing 5.4:
Listing 5.4 Linker PRM File
NAMES ... rtk.o+ ... END
SECTIONS
...
RTK_SEC = NO_INIT 0x1040 TO 0x1F80;
...
![](asset-be.png)
Real Time Kernel Awareness
OSEK Kernel Awareness
190
Microcontrollers Debugger Manual
END
PLACEMENT
...
OS_DATA INTO RTK_SEC;
...
END
The source file (for example: rtk.c) has to be compiled and listed in the NAMES
section of the linker parameter file. To force linking, the name of the object file has to be
immediately followed by a '+'. In this example the variable is linked to the address
0x1040.
If an application is prepared in this way, all declared variables may be inspected in the
data windows of the Debugger. There is no restriction in the complexity of the structures
to describe the global data of the kernel.
NOTE Do not open the terminal window during testing. Errors detected during
reading of a PRM file are written to this window.
OSEK Kernel Awareness
OSEK Kernel provides a framework for building real-time applications.
OSEK Kernel awareness within the debugger allows you to debug your application from
the operating system perspective.
The CodeWarrior Debugger supports OSEK ORTI compliant real-time operating systems
and offers dedicated kernel awareness, using the information stored in your application's
ORTI file.
With CodeWarrior OSEK kernel awareness, you can monitor kernel task information,
semaphores, messages, queues, resources allocations, synchronization, communicating
between tasks, etc.
ORTI describes the applications in any OSEK implementation:
• A set of attributes for system objects.
• A method for interpreting the data obtained.
![](asset-bf.png)

Microcontrollers Debugger Manual
OSEK Run Time Interface
The OSEK Run Time Interface (ORTI) is an interface for development tools to the OSEK
Operating System. It is a part of the OSEK standard (refer to www.osek-vdx.org).
The ORTI enables the attached tool to evaluate and display information about the
operating system, its state, its performance, the different task states, the different operating
system objects etc.
ORTI File and Filename
The ORTI file name has the same name as the application file name, but with the
extension .ort. For instance, if the application file name is winLift_demo.abs, the
ORTI file name is winLift_demo.ort. Otherwise the debugger cannot use the correct
ORTI file.
The ORTI file contains dynamic information as a set of attributes that are represented by
formulas to access corresponding dynamic values. Formulas for dynamic data access are
comprised of constants, operations, and symbolic names within the target file. The given
formula can then be evaluated by the debug tool to obtain internal values of the required
OS objects.
Figure 5.1 ORTI Aware Debugging System
Two types of data are made available to the CodeWarrior IDE debug tool. One type
describes static configuration data that remains unchanged during program execution. The
second type of data is dynamic and this data is re-evaluated each time by the CodeWarrior
IDE. The static information is useful for display of general information and in
![](asset-c0.png)
Real Time Kernel Awareness
OSEK Kernel Awareness
192
Microcontrollers Debugger Manual
combination with the dynamic data. The dynamic data gives information about the current
status of the system.
The information given to the CodeWarrior IDE is represented in a text file (ORTI-File).
The file describes the different objects configured in the OS and their properties. The
information is represented in direct text, enumerated values, Symbolic names, or an
equation that may be used for evaluating the attribute.
The ORTI File is generated when building the project through the OSEK System
Generator. The generated file has the same name and the same location as the executable
file but its extension is .ort.
ORTI File Structure
The ORTI file structure builds on top of the structure of the OSEK OIL file. It consists of
the following parts:
• Version Section - This section describes the version of the ORTI standard used for
the current ORTI file.
• Implementation Definition Section - This section describes the method to use to
interpret the data obtained for the value. This section may also detail the suggested
display name for a given attribute.
• Application Definition Section - This section contains information on all objects that
are currently available for a given system. This section also describes the method that
shall be used to reference or calculate each required attribute. This information shall
either be supplied as a static value or else a formula that shall be used to calculate the
required value.

Automating Debugger Startup

Microcontrollers Debugger Manual
Automating Debugger Startup
Often the same tasks have to be performed after starting the Debugger. These tasks can be
automated by writing a command file that contains all commands to be executed after
startup of the Debugger, as shown in Listing 6.1.
Listing 6.1 Example of a Command File to Automate Tasks
load fibo.abs
bs &main t
g
This file first loads an application, then sets a temporary breakpoint at the start of the
function main and start the application. The application then stops on entering main (after
executing the startup and initialization code).
There are several ways to execute this command file:
• Specify the command file on the command line using the command line option -c.
Do this in the application that starts the Debugger (for example, Editor, Explorer, or
Make utility).
Example:
\Freescale\CodeWarrior for Microcontrollers
V6.1\PROG\HIWAVE.EXE -c init.cmd
When you start the Debugger with this command line, it executes the command specified
in the file init.cmd, after loading the layout (or project file).
• Calling the command file from the project file (Listing 6.2). The project file in which
you save the layout and connection component (File > Save) is a normal text file that
contains command line commands to restore the context of a project. Once you
create this file using the save command, you can extend it by a call to the command
file (CALL INIT.CMD). Loading this project using the File > Open command or
the corresponding entry in the Project file executes the commands in this file.
Listing 6.2 Calling a Command File from the Project File:
set Sim
CLOSE *
call \Freescale\DEMO\test.hwl
call init.cmd
• Calling the command file when the Connection Component is loaded. Most
connection components execute the command file STARTUP.CMD once the
connection component is loaded and initialized. By adding the call command file in

Modify a Variable Value
The Debugger allows you to change the value of a variable, as shown in Figure 6.3.
Figure 6.3 Modifying a Variable Value
Double-click on a variable. The current variable value is highlighted and can be edited.
1. Formats for the input value follow the rule from ANSI C constant values (prefixed by
0x for hexadecimal value, prefixed by 0 for octal values, otherwise considered as
decimal value). For example, if the data component is in decimal format and if a
variable input value is 0x20, the variable is initialized with 32. If a variable input value
is 020, the variable is initialized with 16.
2. To validate the input value you can either press the Enter or Tab key.
3. If an input value has been validated by the Tab key, the value of the next variable in
the component is automatically highlighted (this value can also be edited).
4. To restore the previous variable value, press the Esc key or select another variable.
A local variable can be modified when the application is stopped. Since these variables are
located on the stack, they do not exist as long as the function where they are defined is not
active.

Debugger DDE Capabilities
Introduction
The DDE is a form of interprocess communication that uses shared memory to exchange
data between applications. Applications can use DDE for one-time data transfers and for
ongoing exchanges in applications that send updates to one another as new data becomes
available.
NOTE The DDE capabilities of the Debugger are deprecated. Future versions of
the Debugger will have no DDE capabilities. You can use the Component
Object Model (COM) Interface.
DDE Implementation
The Debugger integrates a DDE server and DDE client implementation in the KERNEL.
The DDE application name of the IDF server is "HI-WAVE".
The Debugger DDE support allows you to execute almost any command from the
Command line, that is available within the debugger. There are also special DDE items for
more commonly performed tasks.
This section describes topics and DDE items available to CodeWright clients. In addition
to the required System topic, CurrentBuffer and the names of all CodeWright non-system
buffers (documents) are available as topics.
Driving Debugger through DDE
The DDE implementation in the Debugger allows you to drive it easily by using the DDE
command. To do this, you have to use a program that can send a DDE message (a DDE
client application) like DDECLient.exe from Microsoft.
The service name of the Debugger DDE Server is HI-WAVE and the Topic name for the
Debugger DDE Server is Command.
The following example is done with DDECLient.exe from Microsoft.
1. Run the Debugger and in the Service field in the DDEClient type: HI-WAVE
2. In the Topic field type Command
![](asset-da.png)
Debugger DDE Capabilities
218
Microcontrollers Debugger Manual
3. Push the Connect button of the DDEClient. The following message appears in
DDECLient: Connected to HI-WAVE|Command.
4. In the Exec field of DDECLient type a Debugger command, for example open
recorder and click the Exec button. The command is executed by way of DDE and
a new recorder component appears in the Debugger.
NOTE You can disconnect the DDE in the Debugger. The Debugger can be started
without DDE (this is saved in the project file). To view the current state, open a
command line component and type the following command: DDEPROTOCOL
STATUS. The state must be: DDEPROTOCOL ON to ensure the DDE works
properly.

Preprocessor - Header Directories
This text box determines the list of directories that are to be searched for files named
within the #include directive. A semicolon separates directories. Only listed directories
are searched for files named between < and >. Searching for files named between
quotation marks (""), starts in the directory of the source file containing #include
directive.
The list of header directories can be assigned in a file. In that case, this field contains the
file name (absolute or relative in relation to the project root) with prefix @. Directories are
separated with a semi-colon or new line.
Define the library path matching your CPU (assuming Freescale tools are installed on
C:\Program Files\Freescale):
C:\Program Files\Freescale\lib\<processor>c\include.
Preprocessor - Preinclude File
This text box determines the name of the file included automatically at the beginning of
every source module during analysis, as if #include "string" were present in the
first line. Use the preinclude file to specify predefined macros and variable and function
declarations for a particular compiler, which are not set by default in DA-C analysis. We
have selected the one corresponding to our example: M68k preinclude file (adapt it to your
needs).

Building The Database
Development Assistant for C provides the static code analysis of C source files, as well as
generating various data based on the results.
Analysis of the project source files and generation of the database are divided into two
phases: the analysis of individual program modules and generation of data about global
symbols usage. Results of the analysis are saved in database files on the disk, which
enables their later use in DA-C. You can choose between the unconditional analysis of all
project files and the analysis of changed source files only, using Start > Build database

Debugger Interface
230
Microcontrollers Debugger Manual
Debugger Interface
DA-C v3.5 currently integrates a DAPI interface (Debugging support Application
Programming Interface). Through this interface DA-C is enabled to exchange messages
with the Debugger. The advantages of this connection allow you to set or delete break
points from within DA-C (in an editor, flow chart, graph, browser) and to execute other
debugger operations. DA-C follows the debugger in its operation, since it is always in the
same file and on the same line as the debugger. Thus, usability of both the DA-C and
Debugger is increased. Some configurations are required in order to make efficient use of
this Debugger Interface:
• Installation of communication DLL
• Configuration of Debugger properties
• Configuration of the Debugger project file
DA-C IDE and Debugger Communication
DA-C and the Debugger are both Microsoft Windows applications and communication is
based on the DDE protocol, as shown in Figure 9.10. The whole system contains:
• DA-C
• Debugger
• cDAPI interface implementation DLL - which is used by DA-C (Cdgen32.dll)
• nDAPI communication DLL (provided by DA-C), which is used by Debugger
• Debugger specific DLL for bridging its interface to debugging environment and DA-
C's nDAPI (DAC.wnd)
![](asset-e7.png)
Synchronized Debugging Through DA-C IDE
Debugger Interface
231
Microcontrollers Debugger Manual
Figure 9.10 Communication between DA-C IDE and Debugger
Communication DLL Installation
As described previously, the Debugger needs the nDAPI communication DLL (provided
by DA-C IDE). This dll (called Ndapi.dll) is automatically installed during the Freescale
Tool Kit installation. However, if you install a new release of DA-C you have to follow
this procedure:
In the \Program directory of your DA-C installation, copy the Ndapi32.dll
(Ndapi32.dll version 1.1 or later) and paste it in your current
Freescale\CodeWarrior for Microcontrollers V6.1\PROG directory
(where Debugger is located). Then rename it to Ndapi.dll.
Debugger Properties Configuration
In the DA-C main menu, choose Options > Debugger, the dialog box shown in Figure
9.11 is opened.

Debugger Project File Configuration
Before configuring the project file, close DA-C. Open Debugger (for example, from a
shell) and select File > Open Project from the main menu bar. Select the Project.ini
file from the currently defined working directory (in our case C:\Program
Files\Freescale\WORK\<processor>c\project.ini). We will now add in
the layout of the project the Debugger DA-C component (dac.wnd). In the Debugger
select Component > Open from the main menu bar and choose Dac, as shown in Figure
9.13.

You must save this configuration by selecting File > Save Configuration from the main
menu of the Debugger. This component loads automatically the next time this project is
called. Close the Debugger.
Synchronized Debugging
We can now test the synchronization between the DA-C IDE and Debugger. Run
DA-C.exe and open the project previously created. Open Fibo.c if it's not already
open. Right-click mouse button on Fibo.c source window and select main in the context
menu. The cursor points to the void main(void) { statement. In the main menu
from DA-C, select Debug > Set Breakpoint (or click on the corresponding button on the
debug toolbar), the selected line is highlighted in red, indicating that a breakpoint has been
set. Then select Debug > Run, the Debugger is now started and after a while stops on the
specified breakpoint. Up to now, you can debug from the DA-C IDE with the toolbar, as
shown in Figure 9.15, or from the Debugger.

Microcontroller Debugging
First Steps
Since the initial steps for creating a project are similar, the following information provides
an example of the first few steps of the New Project wizard that apply to creating an
HC(S)08, HC08 or RS08 project. Debugging code using the CodeWarrior IDE requires
that a project be created or exists, which specifies a connection that can be used to debug
the code. This section guides you through the first steps toward code debugging with the
CodeWarrior IDE and the following connections:
•HCS08 Full Chip Simulation
•HCS08 Serial Monitor Connection
•ICS MON08 Interface Connection
•HCS08 P&E Multilink/Cyclone Pro Connection
•HC08 ICS P&E Multilink/Cyclone Pro Connections
•SofTec HCS08 Connection
•HCS08 Open Source BDM Connection
•RS08 Open Source BDM Connection
NOTE The initial project creation steps for RS08 Connections mentioned in Book IV -
RS08 Debug Connections are similar to the first steps mentioned in Debugging
First Steps Using the Wizard.
Technical Considerations
While they can be used to debug code, some of these connections have special technical
considerations, as discussed in the following paragraphs.
Full Chip Simulation Considerations
The Full Chip Simulation (FCS) connection runs a complete simulation of all processor
peripherals and I/O on the user's PC. No development board is required. Each derivative
![](asset-f0.png)
Microcontroller Debugging First Steps
Technical Considerations
240
Microcontrollers Debugger Manual
has a totally different simulation engine to accurately simulate the memory ranges, I/O,
and peripherals for any given derivative.
HC08 Serial Monitor Considerations
The 8/16 bit debugger (and then the CodeWarrior IDE) might be connected to HC08
hardware using the HC08 Serial Monitor connection. This connection supports
communication specifications described in the application note from Freescale.
When the debugger runs the serial monitor connection, it can communicate and debug
hardware running the serial monitor in full compliance with the Freescale Application
Note specifications. Refer to this Application Note for communication hardware
requirements.
ICS MON08 Interface Connection
In-Circuit Simulation (ICS) Mode is a P&E Microcomputer Systems mode of operation
that is a hybrid between In-Circuit Debugging, and Full Chip simulation. In-Circuit
Simulation, or ICS, mode simulates the CPU core instructions on the user's PC.
P&E Multilink/Cyclone Pro Considerations
To use the P&E BDN-Multilink, the drivers from P&E must be installed on the host
computer. Use a parallel cable for communication between the BDM-Multilink and the
host computer. The communication protocol between the BDM-Multilink and the host is
handled by the target driver, which is automatically loaded with the connection.
ICS P&E Multilink/Cyclone Pro
Considerations
In-Circuit Simulation Mode is a P&E Microcomputer Systems mode of operation that is a
hybrid between In-Circuit Debugging, and Full Chip simulation.
SofTec HC08 Considerations
The 8/16 bits debugger (and then the CodeWarrior IDE) might be connected to HC08
hardware using the SofTec HC08.
When the debugger runs the SofTec HC08 connection, it can communicate and debug
HC08-based hardware connected through the SofTec in-circuit debugger/programmer
units, that is:
SofTec Microsystems HC08 ISP Debuggers/Programmers (inDART Series) and Starter
Kits (AK/SK/PK/ZK and newer Series).

13. Depending on CPU derivative selected, additional screens may appear; select startup
code, memory model, and floating point format.
• Minimal startup code - This startup code initializes the stack pointer and calls the
main function. No initialization of global variables is done, giving the user the best
speed/code density and a fast startup time. But, the application code has to care about
variable initialization. This makes this option not ANSI compliant, since ANSI
requires variable initialization.
• ANSI startup code - This performs an ANSI-compliant startup code that initializes
global variables/objects and calls the application main routine.
• Small - The Small memory model is best used if both the code and the data fit into
the 64kB address space. By default all variables and functions are accessed with 16-
bit addresses. the compiler does support banked functions or paged variables in this
memory model, but all accesses have to be explicitly handled.
• None - Do not use floating point for the HC08.
• Float is IEEE32, double is IEEE32 - All float and double variables are 32-bit IEEE32
for the HC08.
• Float is IEEE32, double is IEEE64 - Float variables are 32-bit IEEE32. Double
variables are 64-bit IEEE64 for the HC08.

HC08 Full Chip Simulation
Full Chip Simulation (FCS) connection runs a complete simulation of all processor
peripherals and I/O on the user's Personal Computer. Because of this it does not require an
MCU development board to be connected to your PC. Each derivative has a totally
different simulation engine to accurately simulate the memory ranges, I/O, and peripherals
for a given derivative (for more information on selecting a specific derivative, see the
Select Device Option section below.
Configuration Procedure
Choose the Full Chip Simulation option from the Set Connection dialog box. See Figure
11.1.
Figure 11.1 Set Connection Dialog Box - Full Chip Simulation Option
When you have selected this option, the Connection list menu becomes the HCS08FCS

Full Chip Simulation Module Commands
The HCS08FCS Menu contains the Full Chip Simulation commands for the modules that
have specialty commands associated with them for a chosen device. For more information
about specific module commands, refer to the Full Chip Simulation section describing the
particular module.
Run Till Cycle Option
The Run Till Cycle command lets you begin execution of code, and stop execution when
the specified cycle count is reached. Note that the parameter given is not the number of
cycles that executed, but rather the total cycle count of the simulator (displayed in the
Register Window).
![](asset-100.png)
HC08 Full Chip Simulation
Configuration Procedure
256
Microcontrollers Debugger Manual
This command is extremely useful for verifying specific timings of a given event, running
until a given event is complete, or just before it completes to enable stepping through the
event or any application where cycle-timed execution is desired.
Initialize Input Ports On Startup
The Initialize Input Ports on Startup option initializes all simulated inputs to $00 when
the software is started, or when the Device Mode or Debug Target is switched. This
initialization doesn't apply to a reset command. When you change this option, the new
state takes effect the next time HiWave is started (or Device Mode/Debug Target is
switched).
View Register Files Option
The View Register Files option in the HCS08FCS Menu also gives you the option of
running the register file viewer/editor. If register files are available for the device that you
have chosen, the Choose a Register Block dialog box (see Figure 11.4) is opened. You
may also open it by entering the R command in the Command Window command line.
Figure 11.4 Choose A Register Block Dialog Box
If register files have been installed on the host computer, selecting a block brings up the
Register Block register listing in the Timer Interface Module dialog box (see Figure 11.5),
which shows a list of the associated registers, their addresses, and their descriptions. This
begins interactive setup of system registers such as I/O, timer, and COP watchdog.
Figure 11.5 Timer Interface Module Dialog Box - Register Listing
Selecting a file in this dialog box brings up the Register Window (see Figure 11.6), which
displays the values and significance for each bit in the register. The registers can be

ADC Module Option
In Full Chip Simulation Mode (FCS), this option lets you simulate all the functionality of
the Analog to Digital Conversion (ADC) module including data input on all ADC
channels, flag polling, interrupt operation as well as the bus and CGMXCLK reference
clock sources. FCS mode uses the buffered input structure to simulate the ADC inputs.
The user can queue up to 256 data values. To queue the ADC Input Data, use the ADDI
command in the command prompt. If the data parameter is given, the value is placed into
the next slot in the input buffer. Otherwise, if no parameter is provided, a window is
displayed with the input buffer values. Input values can be entered while the window is
open. An arrow points to the next value to be as input to the ADC. The conversion takes
place after a proper value is written to the ADC Status and Control register. Once the
conversion occurs, the arrow moves to the next value in the ADC Buffer.
Figure 11.8 ADC IN Buffer Display
At any point, the ADCLR command can be used to flush the input buffer for the ADC
simulation.
After the conversion is complete, the first queued value is passed from the data buffer into
the ADC data register. It can be observed in the memory window by displaying the
memory location corresponding to the ADC data register.
Figure 11.9 Memory Component Window
Conversion completion sets the appropriate flag. If you enable interrupts, the Program
Counter changes flow to the interrupt routine (as defined in the vector space of the MCU).

ADC User Commands
The following ADC commands are available on the HC08 processor in Full Chip
Simulation mode.
ADDI Command
The ADDI command allows the user to input the data into the ADC converter. If a data
parameter is given, the value is placed into the next slot in the input buffer. Otherwise, if
no parameter is given, a window appears with the input buffer values. Input values can be
entered while the window is open. An arrow points to the next value to be sent to the
ADC. The maximum number of input values is 256 bytes.
Syntax
>ADDI [<n>]
Where:
<n> The value to be entered into the next location in the input buffer.
Example
>ADDI $55
Set the next input value to the ADDI to $55
>ADDI
Pull up the data window with all the input values.
ADCLR Command
Use the ADCLR command to flush the input buffer for ADC simulation. This resets the
input data buffer and clears out all values. Notice that if the ADC is currently using a
value, this command does not prevent the ADC from using it. See ADDI Command for
information on how to access the input buffer of the ADC interface.

Clock Generation Module Option
In Full Chip Simulation Mode, this option lets you simulate all functionality of the Clock
Generation Module (CGM), including:
• Phase Locked Loop (PLL) generation
• Automatic lock detection
•Interrupt
• Acquisition
• Tracking
• Flag polling
Full Chip Simulation mode uses simulated External Oscillator Frequency change
command (XTAL) to allow the user to input the desired XTAL value. To check the
current value of the External Oscillator, Bus Frequency and CGMXCLK Frequency, open
the HCS08FCS menu, then select Clocks Module > Show MCU Clocks.
Figure 11.10 Show MCU Clocks Menu
Once you select the MCU Clocks Menu, the Cycles window containing all of the above-
mentioned Clock Frequencies appears.

Once the CGM is properly configured, the user can monitor the status of the PLL by
polling the corresponding flag. If PLL interrupt is enabled, FCS jumps to an appropriate
subroutine as long as the interrupt vector is properly defined. To observe the flag going up
as a result of the corresponding CPU event, situate your Memory Window on the memory
location of the CGM Status and Control register.
Figure 11.12 Memory Window
For more information on how to properly configure Clock Generation, refer to the
reference manual corresponding to the microprocessor that you are using.
CGM Commands
The following Clock Generation commands are available on the HC08 processor.
XTAL Command
Use the XTAL command to change the value of the simulated external oscillator. This in
turn affects the input to the PLL/DCO, and therefore the bus frequency. The P&E
simulator is a cycle-based simulator, so changing the XTAL value does not affect the
speed of simulation; it does, however, affect the ratio in which peripherals receive cycles.
![](asset-106.png)
HC08 Full Chip Simulation
Configuration Procedure

Microcontrollers Debugger Manual
Certain peripherals that run directly from the XTAL run at different speeds than those that
run from the bus clock.
Syntax
>XTAL <n>
Where:
n, by default, is a hexadecimal number, representing the simulated frequency of an
external oscillator. Adding the suffix “t” to the n parameter forces the input value
to be interpreted as base 10.
Example
>XTAL
Brings up an input window. The default base for this input value is 10. However,
this value can be forced to a hexadecimal format by adding the suffix “h”.
High-Resolution PWM Module
In Full Chip Simulation Mode, this option lets you simulate all functionality of the High
Resolution PWM (HRP) module, including:
• pulse width modulation
• flag polling
• interrupt enabled mode of operation
• variable period and dead time insertion
• shutdown input for fast disabling of outputs
To ensure that the HRP firmware is functioning as expected, the user can observe the
toggling of I/O pins that are multiplexed with the HRP module. To do that, the HRP
module has to be configured for the desired period with the enabled output on
corresponding TOP and BOT pins. The Memory Window displays the address of the
register corresponding to the appropriate I/O port.

Figure 11.13 Memory Component Window
If you enable the Shutdown pin on the HRP module, you can observe the SHTIF Flag via
the Memory window once the Shutdown event takes place. If you enable the HRP
interrupt, the FCS jumps to an appropriate subroutine as long as the HRP interrupt vector
is properly defined. To observe the SHTDWN Interrupt Flag going up as a result of the
corresponding CPU event, situate your Memory Window on the memory location of the
HRP Control register.
To observe the accuracy of the HRP module operation, the user can observe the number of
CPU cycles that it takes for the event to occur. The cycle counter is only incremented as
the user steps through the code. To determine the exact amount of cycles over which the
event occurs, one can either observe the cycle display in the Register Window or use the
built in simulation commands. To display the current number of cycles in the Command
window, use the CYCLES command. To change the number of cycles in the cycle counter,
use CYCLES <n>, where <n> is the new cycle value. If the number of cycles has been
pre-calculated, use CYCLE 00 to reset the number of cycles and GOTOCYCLE <n> to
run through the code until the place where the expected event occurs.

CYCLES Command
The CYCLES command changes the value of the cycles counter. The cycles counter
counts the number of processor cycles that have passed during execution. The Cycles
Window shows the cycle counter. The cycle count can be useful for timing procedures.
Syntax
>Cycles <n>
Where:
<n> Integer value for the cycles counter
Examples
>CYCLES 0
Reset cycles counter
>CYCLES 1000
Set cycle counter to 1000.
GOTOCYCLE Command
The GOTOCYCLE command executes the program in the simulator beginning at the
address in the program counter (PC). Execution continues until the cycle counter is equal
to or greater than the specified value, until a key or the Stop button on the toolbar is
pressed, until it reaches a break point, or until an error occurs.
Syntax
>GOTOCYCLE <n>
Where:
<n> Cycle-counter value at which the execution stops
Example
>GOTOCYCLE 100
Execute the program until the cycle counter equals 100.

SHTDWN Command
When you enable the Shutdown pin in the High Resolution PWM Control Register
(HRPCTRL), you can use this command to change the state of the SHTDWN pin. The
Shutdown pin then takes on this state after the simulator executes the next step. If
interrupts are enabled, issuing a SHTDWN 0 command triggers an interrupt that is cleared
until the SHTIF bit is cleared in the HRPCTRL and a SHUTDWN 1 command is issued.
Note that this interrupt is both edge and level sensitive.
If the SHTDWN pin is not enabled in the HRPCTRL, this command has no effect.
Syntax
>SHTDWN <n>
Where:
<n> = 1 or 0, representing the state of the SHTDWN pin on the next simulated
clock cycle.
Example
>SHTDWN 0
Change the state of the SHTDWN pin to 0.
Input/Output (I/O) Ports Module
In Full Chip Simulation Mode (FCS), this option lets you simulate all input and output
functionality of the Input/Output (I/O) Ports module. FCS mode uses a set of designated
commands to simulate the input and output activity on corresponding I/O port pins. To
define an input state of the specific port, write the INPUT <x> <n> command in the
Command line window. The <x> represents the corresponding I/O port, while the <n>
stands for the input value to write to this port. At the same time, you can use the INPUTS
command to bring up the Simulated Port Inputs for all general I/O ports. It displays the
current simulated values to all applicable input ports. See Input/Output Ports Commands
for more information about the various forms of this command.

External Interrupt Module
In Full Chip Simulation (FCS) Mode, this option lets you simulate the input, flag polling
and interrupt functionality of the External Interrupt (IRQ) module. The FCS Mode uses
the INPUTS command to let the user monitor and change the simulated value of the IRQ
input pin state. See the documentation for Keyboard Interrupt Commands for more
information about the various forms of this command. When the user enters the INPUTS
command into the command line prompt, the Simulated Port Inputs window appears. In
addition, the user can directly modify the state of the IRQ pin using the IRQ <n>
command (documented below).
The occurrence of the IRQ event sets the appropriate flag in the corresponding IRQ
register. The user can poll the IRQ flag if the Polling Mode is simulated. In the Interrupt
Mode, the simulator branches to an appropriate interrupt subroutine as long as the IRQ
interrupt vector is properly configured. For more information on IRQ configuration, refer
to the Freescale user manual for your microprocessor.
Following the IRQ event, you can observe the IRQ Flag going up in the IRQ Status and
Control register.

simulates a logic-low state on the IRQ pin.
Keyboard Interrupt Module
In FCS Mode, this module simulates all functionality of the Keyboard Interrupt (KBI)
module including the edge-only, edge and level interrupt, and flag polling modes of
operation. FCS mode uses simulated port inputs to trigger the KBI event from the proper I/
O port pin. To define an input state of the specific port, write the INPUT<x> <n>
command in the Command line window. The <x> represents the corresponding I/O port,
while <n> stands for the input value to write to this port. At the same time, you can use

the INPUTS command to bring up the Simulated Port Inputs for all general I/O ports. It
displays the current simulated values to all applicable input ports. See FCS Timer
Interface Module Commands for more information about the various forms of this
command.
Figure 11.20 Simulated Port Inputs Dialog Box
Use the Simulated Port Inputs dialog box to reconfigure the input value to any I/O port. To
trigger the event, manipulate the inputs to the port in the appropriate manner, depending
on whether the KBI is configured for edge-only or edge and level. Once the KBI event
takes place, the KEYF Flag bit, which is a part of the Keyboard Status and Control
register, can be observed in the Memory Window.

Multi-Master Inter-Integrated Circuit
Module
In Full Chip Simulation Mode, this module simulates all functionality of the Multi-Master
Inter-Integrated Circuit (MMIIC) module including:
• Flag polling
• Interrupt enabled mode
• Transmission and reception of external data
• Master and slave modes of operation
• START and STOP signal generation detection
• Acknowledge bit generation detection
The FCS mode uses the buffered input/output structure to simulate MMIIC inputs. The
user can queue up to 256 data bytes into the input buffer. The output buffer of the USB
module can also hold 256 output bytes. To queue the MMIIC Input Packets, use the
IICDI <...> command in the command prompt. If the MMIIC packet parameters are
properly defined, the packet is placed into the next slot in the input buffer. Otherwise, if no
parameters are provided, an MMIIC Input Buffer window is displayed. Different MMIIC
packet parameters can be entered while the window is open including START, STOP,
ACK, NACK and data bytes. An arrow points to the next byte to be used next as input to
the MMIIC. The data from the MMIIC input buffer is written to the MMIIC module
registers once the MMIIC module is turned on and properly configured for receiving data
from an external MMIIC device. Once the simulation of the data transmission is over, the
arrow moves to the next value in the MMIIC Input Buffer.
Figure 11.23 IIC Input Buffer Display
![](asset-111.png)
HC08 Full Chip Simulation
Configuration Procedure
273
Microcontrollers Debugger Manual
The MMIIC data input/output log buffer simulation allows the user to gain access to the
past 256 MMIIC data bytes that have been shifted in and out of the module. To bring up
the IIC IN/OUT LOG buffer dialog box, use the IICDO command.
Figure 11.24 IIC IN/OUT LOG Buffer Display
At any point, the IICCLR command can flush the input as well as input/output log MMIIC
buffers.
After the MMIIC simulated input is received, the first queued in data byte is passed from
the data buffer into the corresponding MMIIC module registers. It can be observed in the
Memory Window by displaying the appropriate register location there.
Figure 11.25 Memory Component Window
The user can also observe different MMIIC flags in the Memory Window. If the module is
run in Flag Polling mode, poll the flag corresponding to the expected MMIIC event. If the
MMIIC interrupts are enabled, the FCS jumps to an appropriate subroutine as long as the
MMIIC interrupt vectors are properly defined.
For more information on how to configure the MMIIC module for desired operation, refer
to the Freescale user manual corresponding to your microprocessor.

Multi-Master Inter-Integrated Circuit Module
Commands
The following commands are available for multi-master inter-integrated circuit
manipulation.
IICDI Command
The IICDI command allows the user to input data into a buffer of data which is shifted into
the MMIIC module when it receives data from an external device. If a data parameter is
given, the value is placed into the next slot in the input buffer. If no parameter is given, a
window appears displaying the input buffer values. You can enter input values while the
window is open. The maximum number of input values is 256.
This command is useful for either inputting response data from a slave target or for
inputting data packets from an external master. Note that when the microprocessor
attempts to read an acknowledge from an external device, and the next value in the buffer
is neither ACK nor NACK, the microprocessor automatically receives an ACK signal (i.e.
assumes ACK unless NACK is specified).
Syntax:
>IICDI [<n>][START][STOP][ACK][NACK]
Where:
<n> The value to be entered into the next location in the input buffer
START indicates the incoming START signal
STOP indicates the incoming STOP signal
ACK corresponds to ACK signal
NACK corresponds to NACK signal
For a detailed description of the IIC protocol and the proper way to configure the
IIC module, refer to the Freescale user manual for your microprocessor.
Example:
>IICDI
Pulls up the data window with all the input values
>IICDI 22 33
This is an example of data being returned from a slave device. Once the MCU
transmits a start signal and the target address, it receives an ACK from the slave
device. An ACK is implied unless a NACK is specified via the IICDI command.
![](asset-113.png)
HC08 Full Chip Simulation
Configuration Procedure
275
Microcontrollers Debugger Manual
The next two data bytes read are 22 and 23. If the microprocessor attempts to read
another byte, it gets an $FF value followed by a NACK signal (NACK because
nothing remains in the input buffer). The receiving device then generates a STOP
signal. A more exact input from a device designed to return two bytes is:
>IICDI ACK 22 ACK 23 NACK
MMIIC in master mode transmits to a slave. If the slave device acknowledges all
output bytes of the transmitting device, there is no need to specify an input packet.
If the master device is going to transmit an address and two bytes, the following
packet is equivalent to no packet:
>IICDI ACK ACK ACK
If, however, the slave receiver is designed to generate a NACK signal after the
second received data byte, the proper response packet is:
>IICDI ACK ACK NACK
The address result being the first ACK, the first data result being the second ACK,
and the second data byte being the NACK.
MMIIC in MASTER mode is not acknowledged by any Slave:
>IICDI NACK
If the NACK signal is entered before our master device transmits a START signal,
then the master device receives a NACK signal when it tries to read an
acknowledge after the address is output. The master device then generates a STOP
signal and releases the BUS.
MMIIC in SLAVE mode receives a Write from an external Master:
This example is for an external master which is writing to the microprocessor
configured to simulate the slave mode operation. The packet contains both START
and STOP signals which put the simulated device into the slave mode.
>IICDI START 55 AA 22 STOP
This input adds five values to the input queue, which is a packet from an external
master, including the following values:
• A start signal comes in.
• The address $55 comes in specifying a write (slave receive). The Address
Register of the current simulated device was previously set to $55.
• The data byte $AA comes in.
• The data byte $22 comes in.
•A STOP signal comes in.

Syntax
>IICDO
Example

a value, this command allows the MMIIC to finish the transfer.

FCSMSCAN08 Background and Assembly
Example
The MSCAN08 peripheral is a scalable control area network (CAN) 2.0 compliant device
that allows microcontrollers to exchange data between themselves at high speeds. This is
done through a high-speed serial link that is deterministic and reliable. CAN devices are
often utilized in automobiles, where multiple microcontrollers need to be connected into a
network. The CAN specification indicates that any unit on the bus can be a master at any
time, where they can send a message to another unit whenever they wish if the bus is free
to do so. All of these messages can be setup through the CAN I/O commands built into the
simulator. This section goes through an example of this, showing how the simulator can be
used to test out code for driving the CAN peripheral
Listing 11.1 is an example assembly program that exercises the CAN 2.0 peripheral on the
68HC908AZ60. The source assembly file can be download from P&E Microcomputer
website at www.pemicro.com. With minor modifications this assembly file can be added
and compiled as a part of your Freescale project. It initializes the CAN peripheral on the
microcontroller for operation and uses interrupts from the CAN peripheral to service
requests from other controllers. Once the code is compiled and loaded into the
microprocessor that you are using, simulator commands can be used to emulate the CAN
messages that come from the host. Let us first break down what is being done in the
example program.
FCSDemo CAN Program
This code simply sets up the CAN controller to be ready to receive CAN messages
intended for hexadecimal address 0x01234567. Note that this peripheral allows the user to
setup filters for address matching, where only certain bit fields of the address need to
match in order to receive the data. In our case we just setup the filters for 32-bit exact
match. An interrupt service routine is created for the CAN peripheral and is used to collect
messages that are received.
The code also tries to send out three fixed messages in memory out to the network. Each
of these messages has three different locations that they are sent to. The priorities for the
messages are also setup to be different, to show how prioritization works with the CAN
peripheral.

So how is the code laid out in order to handle this? The beginning of the code shows
symbol defines for addresses within memory for RAM, Flash, and interrupt vectors. The
CAN address is specified here as well. Also included are the register file definitions,
![](asset-11e.png)
HC08 Full Chip Simulation
Configuration Procedure
286
Microcontrollers Debugger Manual
which give the addresses of peripheral registers on the microcontroller. Following this
comes the variable declarations for pointers, counters, and buffers for the received data.
In the Flash ROM, the message descriptions are given, which indicate the destination
address, message priority, message length, and the actual data. Note that the number of
data bytes can be variable sizes from 0-8. The information needed in these descriptions
can be found in the CAN specification and the 68HC908AZ60A datasheet.
After the message descriptions come the actual code, where there are some procedures for
handling different tasks. The first is the initialization procedure, which sets up the registers
in the CAN peripheral for the intended operation. The CAN peripheral is also enabled at
the end of the routine. After this comes the start of the application in the MAIN_INIT
procedure, where we call the initialization routines, initialize the pointers and counters,
and wait for an interrupt to occur. There is one interrupt service routines for the CAN
peripheral in this code which is triggered when the peripheral receives CAN messages
specifically intended for it. Note that this application is totally interrupt driven, where the
code is driven by any events that take place through the CAN peripheral.
The end of the code shows the interrupt vectors for the microcontroller, where the CAN
interrupts and the RESET vector are included. All other vectors are pointed to a dummy
interrupt service routine that simply returns from the interrupt.
Once the above mentioned assembly code is compiled as a part of the Freescale project,
one can step through it in the Full Chip Simulation mode. The execution starts
automatically at the reset location within the code. We are now ready to start debugging
the code.
First, we need to step through the beginning of the code in the simulator in order to allow
the code to initialize the microcontroller and the CAN peripheral and get ready to start
receiving CAN packets from the network. So, the user needs to step through the beginning
of the code until they get to the main loop with the t command.
At this point we are ready for CAN packets to come into the device. There are three
specific commands in the simulator for testing the CAN peripheral: CANIN, CANOUT,
and CANCLR (see detailed MSCAN commands description below). The CANIN
command allows a user to specify messages coming into the CAN peripheral. The
CANOUT command allows a user to see the packets that were sent out from the CAN
peripheral. The CANCLR command allows the user to clear all input and output buffers of
CAN packets.
Now we can use the CANIN command to specify CAN packets that come from the
network to our device. When a user types this command in the simulator, the CAN IN
window appears as shown in Figure 11.26. There are no CAN packets specified yet in the
window, so we will enter some into it.
![](asset-11f.png)
HC08 Full Chip Simulation
Configuration Procedure
287
Microcontrollers Debugger Manual
Figure 11.26 CAN IN Display
Input packets can be added by double-clicking in the window where the packet is to go or
by selecting the row for the packet and clicking the OK button. At this point a new
window comes up as shown in Figure 11.27. It is in this window that the user can specify
the parameters of the message. The Packet Type list menu allows the user to select the
type of CAN packet, that is, a DATA, REMOTE, ERROR, or OVERLOAD packet. The
CAN address for the input can be entered in the CAN Address edit box. The address
format can be set to be standard (11 bits) or extended (29 bits). Note that if you select an
ERROR or OVERLOAD packet, then the DATA field and CAN Address fields are
unused and are grayed out. For DATA and REMOTE packets, the DATA field must be
filled with the appropriate data. Let’s demonstrate how to fill these fields for a data packet
coming in to the device from the network.
Figure 11.27 CAN Packet Dialog Box
As an example, let us assume that another node in the network wanted to send a packet
containing 8 bytes (0,1,2,3,4,5,6,7) to our device at address $01234567. In this case we
want to set the packet type to DATA, the CAN address to $01234567, the address format
to Extended, and the data field for the given 8 bytes. This is shown in Figure 11.28
through the CANIN command.

Figure 11.28 CAN Example Input Packet
Once the DATA packet information is entered, the CANIN window looks as shown in
Figure 11.29. The user can then set a breakpoint in the interrupt service routine that
handles CAN packets and execute the code by typing GO in the simulator. The user is
now at the CAN ISR. By entering the t command and single stepping through the code,
the user exits the ISR and return to the main loop. The user can then see the resulting data
in the memory window pointed to by the buffptr variable, which is the
0,1,2,3,4,5,6,7 placed in the data packet. Figure 11.30 shows the memory window.
Figure 11.29 CAN IN Display After Data Packet
Figure 11.30 Memory Window Showing Received Data
Now, for the output packets that were setup in the initialization routine, we can see that the
code sends them out from the simulator by using the CANOUT command. The user can
type the command GO in the simulator and let the simulation run for a while. Hit the Enter

key to break the execution. Now type the CANOUT command. Figure 11.31 shows the
result, where all three output packets are seen. Select the first packet by double clicking on
it. Figure 11.32 shows the first CAN packet sent out. Note that the first packet sent out was
the packet with the highest priority. You can now select the other packets in the CAN
OUT window to open them up and see which data packet they were in.

It is possible that a user does not want to enter all of these simulator commands manually.
In this case, use macro files for automated code testing. A macro file permits a user to set
up a sequence of simulator commands to run one after the other within the simulator. So,
the CANIN command can include parameters that specify the type of packet, CAN
address, and data. See the CANIN command in the help file for more details.

FCSMSCAN Commands
You can use the following FCSMSCAN commands with the HC08 processor.
CANCLR Command
You can use the CANCLR command to flush the input and output buffers for CAN
simulation. This resets the buffers and clears out all values. Notice that if the CAN is
currently shifting a value, this command does not prevent the CAN from finishing the
transfer. See CANIN command and CANOUT command for accessing the input and
output buffers of the CAN interface.

The CANIN command allows the user to input data into the CAN. If a data parameter is
given, the value is placed into the next slot in the input buffer. Otherwise, if no parameter
is given, a window is displayed with the input buffer values. Input values can be entered
while the window is open.

• Programmable PIT clock input
• Free running or modulo up count operation
• Flag polling
• Interrupt enabled mode of operation
Once the PIT Status and Control register properly configures the operation of the module,
the PIT Counter starts incrementing. If you enable modulo up count operation, you can

In FCS Mode, this module simulates all functionality of the Serial Peripheral Interface
(SPI) module including:
• flag polling
• interrupt enabled mode
• 8- or 9-bit length data codes
• odd and even parity modes
• transmission and reception of external data
FCS mode uses the buffered input/output structure to simulate SCI inputs. The user can
queue up to 256 data values into the input buffer. The output buffer of the SCI module can
also hold 256 output values. To queue the SCI Input Data, use the SCDI <n> command
in the command prompt. If <n> (the data parameter) is given, the value is placed into the
next slot in the input buffer. Otherwise, if no parameter is provided, a window is displayed
with the input buffer values. Input values can be entered while the window is open. An
arrow points to the next value to be used as input to the SCI. The data from the SCI input
buffer is written to the SCI data register once the SCI module has been turned on and is
properly configured for receiving data from an external serial device. Once the simulation
of the data transmission is over, the arrow moves to the next value in the SCI IN Buffer.

In FCS Mode, this module simulates all functionality of the Slave LIN Interface
Controller (SLIC) Module, including:
• Flag polling
• Interrupt enabled mode
• Transmission and reception of external data
• Check sum generation and verification
• Different message lengths data modes
FCS mode uses a buffered structure to simulate SLIC inputs and outputs. The user can
queue up to 256 data bytes into the input buffer. The output buffer of the SLIC module can
also hold 256 output bytes. To queue the SLIC Input bytes, use the SLCIN command in
the command prompt. The SLIC command brings up a window, which displays a list of
queued in input data. Different SLIC packets can be entered while the window is open. An
arrow points to the next byte to be used as input to the SLIC. Once the SLIC module is
turned on and properly configured for receiving data from an external SLIC device, the
data from the SLIC input buffer is written to the SLIC module identifier or data registers.
After the simulation of the data transmission is complete, the arrow moves to the next

The user can also observe different SLIC flags in the Memory window. If the module is
run in Flag Polling mode, poll the flag corresponding to the expected SLIC event. If the
SLIC interrupts are enabled, the FCS jumps to an appropriate subroutine, as long as the
SLIC interrupt vectors are properly defined. Note that the SLIC State Vector Register
reflects the specific SLIC interrupt that was triggered. CPU overhead for servicing
different LIN interrupts can be significantly decreased by monitoring the state of this
register from within the interrupt subroutine.

Use the Simulated Port Inputs dialog box to reconfigure the input value to any I/O port.
Depending on whether the input capture is set for rising/falling edge, to trigger the event,
first set the port inputs to high or low and then invert the inputs to an opposite value. Once
the Input Capture event takes place, the CHxF can be observed in the Channel Status and
Control register in the Memory window.

Microcontrollers Debugger Manual
If the Timer module is configured for an Output Compare event, once the event takes
place the same CHxF Flag can be observed via the Memory window. If the timer channel
interrupt is enabled, the FCS jumps to an appropriate subroutine as long as the Timer
channel interrupt vector is properly defined. To observe the Timer Overflow Flag (TOF)
increasing as a result of the corresponding CPU event, situate your Memory window on
the memory location of the Timer Status and Control register.
To observe the Pulse Width Modulation (PWM) operation, properly configure the Timer
to operate in the Modulo up count mode, and choose the toggle-on-overflow or clear/set
output on compare events to create a desired duty cycle wave. Once a PWM event takes
place, pin toggle/clear/set behavior corresponding to the Timer configuration can be
observed in the Memory window displaying the IO port associated with a given timer
channel.
To observe the accuracy of the Timer module operation, the user can observe the number
of CPU cycles that it takes for the event to occur. The cycle counter is only incremented as
the user steps through the code. To determine the exact amount of cycles over which the
event occurs, one can either observe the cycle display in the Register window or use the
built in simulation commands. To display the current number of cycles in the Command
window, use the CYCLES command. To change the number of cycles in the cycle counter,
use CYCLES <n>, where <n> is the new cycle value. If an event has a pre-calculated
number of cycles, use CYCLE 00 to reset the number of cycles and GOTOCYCLE <n> to
run through the code until it arrives at the expected event.

FCS Timer Interface Module Commands
The following FCS timer interface module commands are available for use with the HC08
processor.
CYCLES Command
The CYCLES command changes the value of the cycles counter. The cycles counter
counts the number of the processor cycles that have passed during execution. The Cycles
Window shows the cycle counter. The cycle count can be useful for timing procedures.
Syntax
>CYCLES <n>
Where:
<n> Integer value for the cycles counter
Examples
>CYCLES 0
Reset cycles counter
>CYCLES 1000
Set cycle counter to 1000.
GOTOCYCLE Command
The GOTOCYCLE command executes the program in the simulator beginning at the
address in the program counter (PC). Execution continues until the cycle counter is equal
to or greater than the specified value, until a key or the Stop button on the toolbar is
pressed, until it reaches a break point, or until an error occurs.
Syntax
GOTOCYCLE <n>
Where:
<n> Cycle-counter value at which the execution stops
Example
>GOTOCYCLE 100
Execute the program until the cycle counter equals 100.

INPUT<x> Command
The INPUT<x> command sets the simulated inputs to port <x>. The CPU reads this input
value when port <x> is set as an input port.
Syntax
INPUT<x> <n>
Where:
<x> is the letter representing corresponding port
<n> Eight-bit simulated value for port <x>
Example
>INPUTA AA
Simulate the input AA on port A.
INPUTS Command
In Full Chip Simulation and CPU-Only Simulation mode, the INPUTS command opens
the Simulated Port Inputs dialog box shown in Figure 11.54. Use this box to specify the
input states of port pins and IRQ.

FCS Universal Serial Bus (USB) Module
Some of the microcontrollers in the MC68HC08 family contain USB compliant peripheral
devices. These can be low-speed or high-speed USB slave devices. This means that all
USB transfers are initiated by a host (i.e. a personal computer) and that the microcontroller
needs to be setup to respond with the appropriate acknowledgement messages. According
to the USB specification, there are a series of messages that go back and forth between the
host and the device in order to setup and describe the channel for data transfer. All of these
messages can be set up through the USB I/O commands built into the full chip simulator.
This FCS mode simulates all functionality of the Universal Serial Bus (USB) module
including:
• Flag polling
• Interrupt enabled mode
• Transmission and reception of external data
• Endpoint 0/1/2 modes of operation
• USB reset functionality
• STALL, NAK and ACK handshakes
This section goes through an example of assembly code, showing how the simulator can
be used to test out code for driving the USB peripheral.
Listing 11.2 shows an assembly program that exercises the USB full speed peripheral on
the 68HC908JW32. The source assembly file can be downloaded from the P&E
Microcomputer website at www.pemicro.com. With minor modifications this assembly
file can be added and compiled as a part of your Freescale project. It sets the
microcontroller up as a simple USB human interface device (HID) and uses interrupts
from the USB peripheral to service requests from the host. This code can be assembled
and then loaded into the ICS08 simulator for execution, after which simulator commands
can be used to emulate the USB packets that come from the host. Let us first break down
what is being done in the example program.

This code utilizes three endpoints in the USB peripheral: endpoints 0, 1, and 2. As always,
all control transactions occur through endpoint 0. The other endpoints can be set up for
data transfer in the input or output direction, depending on whether data needs to be sent
or received to/from the host. Here, endpoint 1 is setup as an input pipe and endpoint 2 is
setup as an output pipe. The host becomes aware of whether an endpoint is an input or
output through the descriptor tables that are exchanged at the beginning of device
discovery.
It is necessary for the host and the slave to keep retention of the USB state of the device.
There are multiple states for the USB device. The module starts in the POWERED state.
When a USB reset is detected, the module is placed into the DEFAULT state. When the
device receives a SET_ADDRESS standard device request with a valid address, the
device is placed into the ADDRESSED state. Finally, when a SET_CONFIGURATION
standard device request is sent, the device is placed into the CONFIGURED state.
After the device is configured, endpoint 1 is enabled for interrupt transfers from the host.
Endpoint 1 is only capable of sending information out from it. Therefore, only IN packets
are accepted at the endpoint. The report descriptor sets up the endpoint to transfer only 1
byte of data. So when an IN packet comes from the host, the device sends out the data read
from the Port B input pins. Note that the internal pull-ups are enabled for PORTB in the
code (PULLCR), so the default input value sent through endpoint 1 is $FF.
After the device is configured, endpoint 2 is enabled for bulk transfers. Endpoint 2 is only
capable of reading information into it. Therefore, only OUT packets are accepted at the
endpoint. The report descriptor sets up the endpoint to read, at most, 8 bytes of data. So
when an OUT packet comes from the PC, the device reads the data from the packet into a
local buffer.
So, how is the code laid out in order to handle this? The beginning of the code shows
symbol defines for addresses within memory for RAM, Flash, interrupt vectors, and
buffers for USB endpoints. Also included are the register file definitions, which give the
addresses of peripheral registers on the microcontroller. Following this comes the variable
declarations for control packets, pointers, and received data.

HC08 Full Chip Simulation
Configuration Procedure
321
Microcontrollers Debugger Manual
In the FLASH, the descriptor tables are created, which describe the type of USB device,
the configuration, the interface, HID specific information, the endpoints, and reporting
information. All information needed in these descriptors, can be found in the Freescale
documentation describing USB module specifications for the microprocessor that you are
using.
After the descriptors comes the actual code, where numerous procedures are described,
meant to handle different tasks. The first is the initialization procedure, which sets up the
registers for the USB peripheral for the intended operation. The USB peripheral is also
enabled at the end of the routine. The next several procedures are specifically for USB
operation, such as: forcing a device stall, sending the device descriptors to the host,
handling SETUP packets, handling IN packets, and processing OUT packets. After this
comes the start of the application in the MAIN_INIT procedure, where we call the
initialization routines and wait for an interrupt to occur. There are two interrupt service
routines for the USB peripheral in this code: one for endpoint events that occur, and the
other for USB system events such as setups, stalls, and resets. Note that this application is
totally interrupt driven, where the code is driven by any events that take place in the USB
peripheral.
The end of the code shows the interrupt vectors for the microcontroller, where the USB
interrupts and the RESET vector are included. All other vectors are pointed to a dummy
interrupt service routine that simply just returns from the interrupt.
Once the mentioned above assembly code is compiled as a part of the Freescale project,
one can step through in the Full Chip Simulation mode. The execution starts automatically
at the reset location within the code. We are now ready to start debugging the code.
First, we need to step through the beginning of the code in the simulator in order to allow
the code to initialize the microcontroller and the USB peripheral and get ready to start
receiving USB packets from the host. So, the user needs to step through the beginning of
the code until they get to the main loop with the ’t’ command.
At this point we are ready for USB packets to come into the device. There are four specific
commands in the FCS for simulating external input/output as well as reset and clear
functionality of the USB peripheral: USBRESET, USBIN, USBOUT, and USBCLR (for
more detailed information, refer to the USB commands section). The USBRESET
command causes a USB reset, which is identical to a host trying to reset a slave USB
device once it connects to the bus. The USBIN command allows a user to specify packets
coming into the USB peripheral. The USBOUT command allows a user to see the packets
that were sent out from the USB peripheral. The USBCLR command allows the user to
clear all input and output buffers of USB packets. The first command to use for testing the
USB peripheral is the USBRESET command, which places the USB peripheral in the
RESET state. After the USBRESET command, step through the code with a t command to
enter the system interrupt service routine. Enter the t command a few more times to exit
the ISR and return to the main loop.

Now we can use the USBIN command to specify USB packets that come across the USB
bus from the host. When a user types this command in the simulator, the USB IN window
appears as shown in Figure 11.55. There are no USB packets specified yet in the window.
Figure 11.55 USB IN Buffer
Add input packets by double-clicking in the window where the packet is to go or by
selecting the row for the packet and clicking the OK button. At this point a new window
comes up as shown in Figure 11.56. It is in this window that the user can specify the
parameters of the packet. The Packet Type list menu allows the user to select the type of
USB packet, either a SETUP, IN, OUT, DATA0, DATA1, ACK, NAK, STALL, or SOF
packet. Note that if you select a SETUP, IN, or OUT packet, then the DATA field is not
utilized. If you select the DATA0 or DATA1 packet, then the USB Address and
Endpoint edit fields are not used. For SETUP, IN, and OUT packets, the USB Address
and Endpoint fields must be filled with the appropriate data.
Here is an explanation of how to fill these fields for a GET DEVICE DESCRIPTOR
request from the host, which typically comes after the USB reset.
Figure 11.56 USB Packet Setup Dialog Box
The GET DEVICE DESCRIPTOR request between a host and a slave USB device has
three different stages to it, as defined by the USB standard: the setup stage, the data stage,
and the status stage. Figure 11.57 shows the flow of packets between the USB host and
slave devices for a GET DEVICE DESCRIPTOR request as well as the stages. The setup
stage simply consists of a SETUP packet from the host, then a DATA0 packet with the
byte codes that indicate that this is a GET DESCRIPTOR, and the acknowledge (ACK)
packet from the slave.
![](asset-143.png)
HC08 Full Chip Simulation
Configuration Procedure
323
Microcontrollers Debugger Manual
To replicate this stage in the simulator, enter the SETUP packet as shown in Figure 11.56
and the DATA0 packet as shown in Figure 11.58, using the USBIN command. The USB
peripheral automatically sends out the ACK after the code services the other packets,
which are received in the simulator. Once the SETUP and DATA0 packets are entered, the
USBIN window looks as shown in Figure 11.59. The user can then step through the setup
stage by typing t in the simulator. At this point, use the USBOUT command to see that the
ACK packet was sent out by the device, as shown in Figure 11.60. This completes the
setup stage.
We can utilize the same commands for the data stage, using the USBIN command to
create IN and ACK packets. Once the code receives the IN packet, it sends out the
descriptor information with data packets through endpoint 0. The ACK packet then is
needed to end that data stage transfer. Several data stage transfers are needed to send out
all of the device descriptor information. Each data packet can hold only eight bytes, so we
need three transfers in this case. Figure 11.61 shows the USB IN window. Figure 11.62
shows the current appearance of the USB OUT window.

MON08 Interface
Connection
The MON08 connection setting permits a connection to Class 1-4 devices. Refer to the
descriptions below for a definition of each interface class.
MON08 connection mode allows the user to debug code, as the firmware is fully resident
in the FLASH of the microprocessor. The operation of all modules fully reflects the actual
operation of the on-board resources.
Connection Procedure
To make the MON08 Interface debugger connection:
1. Choose the MON08 Interface option from the Set Connection dialog box

Advanced Settings Tab
The Advanced Settings tab allows the user to set specific protocol settings. The following
is an explanation of each part of the Advanced Settings tab.
Figure 12.4 P&E Connection Manager Window - Advanced Settings Tab
Tpd and Tpu Timing Listboxes
Tpd and Tpu Timing Listboxes set the power-up and power-down delay (respectively) that
are observed when power-cycling a target for entry into Monitor Mode. These settings are
only valid for devices with automatically controlled power.
Whenever power is automatically or manually switched off, the software waits for an
amount of time equal to the Tpd delay time before proceeding to the connection protocol.
This is because a board or power supply may have capacitance which holds the power up
![](asset-150.png)
MON08 Interface Connection
Connection Procedure
336
Microcontrollers Debugger Manual
for a short time after the supply has been switched off, but the supply voltage must reach
less than 0.1v before it is turned back on if a Power-On reset is to occur.
Whenever power is automatically or manually switched on, the software waits for an
amount of time equal to the Tpu delay time before attempting to contact the 68HC08
processor. This is to allow time not only for power to be fully available, but to wait until
any reset driver has finally released the RESET line.
Target Has RESET Button
With a class III board, the software occasionally needs to get control of the target. On
systems which are Class III boards with the monitor mode circuitry built-in (including an
RS-232 driver), there is no means to reset the target to gain control. If the board has a reset
button, the software can use this to gain control of the target system. If this option is
checked, the software prompts the user to push the target reset button when a reset of the
target system is desired. If the option is unchecked, the software asks the user to power
cycle the target system to achieve a reset.
For a detailed description of the board or device classes, see Device Class Description.
MON08 Cable Connection Communications Type
This selection box is valid only for Class II hardware configurations using the MON08
cable. For a detailed description of the board or device classes, see Device Class
Description. It allows the user to specify the sequence that the software uses to power up
the ICS system. When the software tries to create a power-on reset condition, two events
must occur:
1. Power of the target MCU must go below 0.1v. This means that the processor cannot be
receiving power from its power pins, nor can it have a significant voltage being driven
on port pins or the IRQ line, as these drive the MCU power back through these pins. It
is crucial, therefore, to have the ICS and the Target both powered down at some point
in time.
2. The processor MON08 configuration pins, including IRQ, must be properly driven
when the target processor resets to drive it into monitor mode. If these pins are not set
up properly before the processor powers up, the processor may start up in user mode.

This option works for many ICS boards as well, but relies on the fact that while the ICS is
powered off, it holds the target in reset until it is powered up itself and has configured the
MON08 configuration pins. The sequence of events in this mode is:
1. Software automatically powers down the ICS.
2. Software asks the user to power cycle their board as follows:

Serial Port Stop Bits
Serial Port Stop Bits allow users of Class 1-4 devices that are experiencing unreliable
communication to increase the number of stop bits to 2.
Pulse IRQ on Stop
The IRQ on Stop allows the users to execute a mechanism to stop a running HC08
microprocessor. For more information, refer to the Stop a Running HC908 Target.pdf
application note that is available from P&E Microcomputer Systems website:

Target MCU Security Bytes
One of the steps that is necessary to properly bypass security is to provide the proper
security code for the information that is programmed into the part. This holds true even
when the part is blank. The security code consists of the 8 values which are currently
stored in Flash locations $FFF6 - $FFFD of the processor.

The MON08 16-Pin Header Signals tab of the P&E Connections Manager window can be

load the security bytes from the same .S19 file which was programmed. The bytes are
loaded from a .S19 file by clicking the Load from S19 button.
IGNORE Security Failure and Enter Monitor
Mode
This MON08 16-Pin Header Signals tab checkbox can be used to cause the software to
ignore a failure to properly pass the 68HC08 security check. If the checkbox is set, the
software attempts to establish monitor mode communications regardless of the security
status. As long as the Baud and Port are correct, and the device is properly powered, this
allows monitor mode entry. If you ignore the security check failure, you may still use
monitor mode, but the ROM/Flash is not accessible.
NOTE If a connection is not established for any reason other than security failure, the
connection dialog box always appears.

STATUS Area
The status area of the MON08 16-Pin Header Signals tab consists of one status string
following the Status: label, and seven items which list the state of the last attempt to
connect to a target and pass security. The description for these items is as follows:
•0 – ICS Hardware loopback detected:
Every ICS or board which supports MON08 has a serial loopback in hardware
which, by connecting the transmit and receive lines, automatically echoes characters
from the PC. A valid character transmitted from the PC is echoed once by the
loopback circuitry on the board and once by the monitor of the target processor itself.
This status indicates whether the first echoed character from the hardware loopback
was received when one of the security bytes was transmitted. If the status is ‘N’,
which indicates that the character was not received, it is most likely due to one of the
following reasons:
– Wrong Com Port specified.
– The baud rate specified was incorrect (probably too low).
– The ICS/Target is not connected.
– No Power to the ICS.
If this status bit is ‘N’, you must correct this before analyzing the rest of the status
bits.
•1 – Device echoed some security bytes:
The monitor resident in a 68HC08 device automatically echoes every incoming
character when it is in monitor mode. A valid character transmitted from the PC is
echoed once by the loopback circuitry on the board and once by the monitor of the
target processor itself. This status indicates whether or not the second echoed
character from the monitor response was received when one of the security bytes was
transmitted. If the status is ‘N’, which indicates that the character was not received,
or not received properly, it is most likely due to one of the following reasons:
– The baud rate specified was incorrect.
– The part did not start the monitor mode security check on reset. Signals to force
monitor mode may be incorrect.
– No Power to the ICS.
If this status bit is ‘N’, you must correct this before analyzing the rest of the status
bits.
•2 – Device echoed all security bytes:
To pass security, the software must send 8 security bytes to the processor. The
processor echoes each of these eight bytes twice. If all 8 bytes did not get the proper
two-byte echo, this flag reads ‘N’. Reasons for this include:
![](asset-155.png)
MON08 Interface Connection
Connection Procedure
341
Microcontrollers Debugger Manual
– The part did not start the monitor mode security check on reset. Signals to force
monitor mode may be incorrect.
– The baud rate specified was incorrect.
– The processor was not reset properly. Check the Target Hardware Type and, if
you are connecting to a class II board, check the MON08 cable communication
connections type in the Advanced Settings dialog box.
•3 – Device signaled monitor mode with a break:
Once the processor has properly received the 8 bytes from the PC software to
complete its security check, it transmits a break character to the PC signaling entry
into monitor mode. This break character is sent regardless of whether the security
check was successfully passed. If a break is not received from the processor, this flag
reads ‘N’. Reasons for this include:
– The baud rate specified was incorrect.
– The processor was not reset properly. Check the Target Hardware Type. If you
are connecting to a class II board, check the MON08 cable communication
connections type in the Advanced Settings dialog box.
•4 – Device entered monitor mode:
Once the software has received, or failed to receive, a break from the processor, it
attempts to communicate with the monitor running on the M68HC08 processor. It
tries to read the monitor version number by issuing a monitor mode read. If the
processor fails to respond properly to this command, this flag reads ‘N’.
•5 – Reset was Power-On Reset:
If the device properly entered monitor mode (4), the software reads the reset status
register (RSR). This read does not affect the security sequence, and occurs purely for
diagnostic reasons. The RSR indicates the conditions under which the processor
underwent the last reset. For the software to pass the security check properly, it
MUST first cause the processor to undergo a Power-On Reset. The software reads
the RSR to determine if the last reset was indeed caused by power-on. The result of
the RSR read is indicated in parentheses after the flag value. If the highest bit is not
set then the reset was not a power-on reset, and the flag reads ‘N’. Reasons for this
include:
– The processor did not power all the way down because power was being supplied
to the processor through either the port pins, IRQ line, RESET line, or power
pins.
– The voltage driven on the power pin of the processor did not go below 0.1 volts.
– The processor was not reset properly. Check the Target Hardware Type. If you
are connecting to a class II board, check the MON08 cable communication
connections type in the Advanced Settings dialog box.
![](asset-156.png)
MON08 Interface Connection
Connection Procedure
342
Microcontrollers Debugger Manual
•6 – ROM is accessible (un-secured):
If the device properly entered monitor mode (4), the software reads locations $FFF6-
$FFFF to determine if the processor passes the security check. Memory locations
which are invalid or protected read back from the device as $AD. If all bytes from
$FFF6-$FFFF read a value of $AD, it is assumed the device is secure, and the flag
value is an ‘N’. If all flags 0-5 register a value of ‘Y’ and flag 6 registers a value of
‘N,’ then the reset process has occurred correctly except that the security code used
to pass security was incorrect. Specify the correct security code and try again, or
IGNORE the security failure and erase the device. Once you erase a secured device,
you must exit the software and restart it in order to pass security.

Device Class Description
The following device information summarizes the different classes of boards available to
the user. Detailed information about specific devices is available from Freescale.
Class 1 Device
ICS Board with processor installed. This is the standard and most common configuration
of the ICS08 boards. In this configuration, the processor is resident in one of the sockets
on the ICS board itself. The processor can be debugged and programmed in this
configuration, and an emulation cable containing all the processor I/O signals can be
connected to the user's MCU development board. In this configuration, the ICS board
hardware can automatically power up and down the processor in order to pass security in
the simplest fashion. The user must be sure not to provide power from the MCU
development board, up through the emulation cable, to the processor pins themselves,
when this dialog box appears. This is so that the software, when attempting to establish
communications, can fully power the processor down. The software running on the PC
controls power to the user’s MCU development board via the serial port DTR line.
Class 2 Device
ICS Board without processor, connected to the user’s microprocessor system via MON08
Cable. In this configuration, there is no processor resident in any of the sockets of the ICS
board itself. The processor is mounted down in the user’s MCU system. The connection
from the ICS board to the user’s MCU system is accomplished via the 16-pin MON08
connector. In this configuration, since the ICS does not control power to the processor, the
user is prompted to turn the processor's power supply on and off. Turning off the power
supply is necessary to pass the initial security mode check and access the Flash on the
processor. A simple reset is not enough; to pass the security check, you must first force the
processor to encounter a POR (power-on reset) which requires that the processor's voltage
dip below 0.1v. Once security is passed, resetting the device or re-entering the software is
easier.
Class 3 Device
Custom Board (no ICS) with MON08 serial port circuitry built in. In this configuration,
the ICS board is not used at all. The user must provide a serial port connection from the
PC, and provide all hardware configurations necessary to force the processor into MON08
mode upon reset. This includes resets both internal and external to the processor. In this
configuration, because the software does not directly control power to the processor, the
user is prompted to turn the processor's power supply on and off. The user is be prompted
to turn power on and off to reset the microprocessor, as the PC doesn't have control of the
microprocessor reset. Turning off the power supply is necessary to pass the initial security

mode check and access the Flash on the processor. A simple reset is not enough; to pass
the security check, you must first force the processor to encounter a POR (power-on reset)
which requires that the processor's voltage dip below 0.1v. Once security is passed,
resetting the device or re-entering the software is easier. Class 3 selection also applies to
use of the ICS board with the two-pin blank part programming connector.
Class 4 Device
Custom Board (no ICS) with MON08 serial port circuitry and additional auto-reset circuit
built in. In this configuration, the ICS board is not used at all. The user must provide a
serial port connection from the PC and all hardware configuration necessary to force the
processor into MON08 mode upon reset. In addition, the user must include an extra circuit
which allows the reset line of the processor to be driven low from the DTR line of the
serial port connector (Pin 4 on a DB9). The following diagram shows the additional
connection needed to reset from a DB9 serial connector.
Figure 12.15 Reset Connection
In this configuration, because the software does not directly control power to the
processor, the user is prompted to turn the processor's power supply on and off. Turning
off the power supply is necessary to pass the initial security mode check and access the
Flash on the processor. A simple reset is not enough; to pass the security check, you must
first force the processor to encounter a POR (power-on reset) which requires the
processor's voltage to dip below 0.1v. Once security is passed, resetting the device is
facilitated by the above circuitry.

ICS Mode
In-Circuit Simulation (ICS) Mode is a P&E Microcomputer Systems mode of operation
that is a hybrid between In-Circuit Debugging, and Full Chip simulation. P&E has
combined the benefits of each of these modes, while minimizing their respective
deficiencies.
ICS mode simulates the CPU core instructions on the user's PC. However, Inputs/Outputs
are read directly from the user's development device, and certain modules are run on the
actual device. Any instructions that affect an I/O location, for example, lda PORTA or
sta PORTA, also use data from the real device. This allows for all the benefits of full
chip simulation (Cycle by Cycle accuracy, unlimited breakpoints, and speed, to name just
a few), while allowing the obvious benefit of garnering relevant signals from actual
hardware.
In-Circuit simulation requires a user to have a connected MCU Device, be it a
development board, prototype hardware, or simply a device placed in a simple circuit on a
breadboard. Once connection is established, the P&E Interface loads a .MON file to the
microcontroller itself. This .MON file is the ICS-Kernel: it constantly runs on the device,
and interacts with the P&E software to provide information about changing I/O and any
peripherals that are running on the device itself.
The following modules are run on the actual device when in ICS mode, and as such their
Simulation commands become unnecessary, and therefore do not function:

specific protocol settings. The following is an explanation of each part of the advanced
settings tab.
Figure 13.4 P&E Connection Manager Window - Advanced Settings Tab
Tpd and Tpu Timing Textboxes
Tpu and Tpd set the power-up and power-down delay (respectively) that is observed when
power-cycling a target for entry into Monitor Mode. These settings are only valid for
devices with automatically controlled power.
Whenever power is automatically switched off, or is manually requested to be switched
off, the software waits for an amount of time equal to the Tpd delay time before
proceeding to the connection protocol. This is because a board or power supply may have
capacitance which holds the power up for a short time after the supply has been switched
off, but the supply voltage must reach less than 0.1v before it is turned back on if a Power-
On reset is to occur.
Whenever power is automatically switched on, or is manually requested to be switched on,
the software waits for an amount of time equal to the Tpu delay time before attempting to
contact the 68HC08 processor. This is to allow time not only for power to be fully
available, but to wait until any reset driver has finally released the RESET line.

Target Has RESET Button
In Class III boards, the software occasionally needs to get control of the target. For a
detailed definition of board classes, see Device Class Description. On systems which are
Class III boards with the monitor mode circuitry built-in (including RS-232 driver), there
is no means to reset the target to gain control. If the board has a reset button, the software
can use this to gain control of the target system. If this option is checked, the software
prompts the user to push the target reset button when a reset of the target system is desired.
If the option is unchecked, the software prompts the user to power cycle the target system
to achieve a reset.
MON08 Cable Connection Communications Type
This selection box is valid only for Class II hardware configurations using the MON08
cable. For a detailed definition of board classes, see Device Class Description. It allows
the user to specify the sequence that the software uses to power up the ICS system. When
the software tries to create a power-on reset condition, two events must occur:
1. Power of the target MCU must go below 0.1v. This means that the processor cannot be
receiving power from its power pins, nor can it have a significant voltage being driven
on port pins or the IRQ line, as these drive the MCU power back through these pins. It
is crucial, therefore, to have the ICS and the Target both powered down at some point
in time.
2. The processor MON08 configuration pins, including IRQ, must be properly driven
when the target processor resets to drive it into monitor mode. If these pins are not set
up properly before the processor powers up, the processor may start up in user mode.
Power Up and Power Down Radio Buttons
Power Down ICS button prompts the user to power down the board, Power Up ICS
button prompts the user to power up their board.
This is the default option and works for most, if not all, ICS08/Target Board solutions. It
requires the user go through two dialog box stages, and requires more time than simply
cycling the power.
1. Software automatically powers down the ICS.
2. Software prompts the user to power down the board as follows:

Cycle Power Radio Button
Power Down ICS button asks the user to power cycle their board. Power UP ICS button
does the opposite.
This option works for many ICS boards as well, but relies on the fact that while the ICS is
powered off, it holds the target in reset until it is powered up itself and has configured the
MON08 configuration pins. The sequence of events in this mode is:
1. Software automatically powers down the ICS.
2. Software asks the user to power cycle their board as follows:

microprocessor. For more information, refer to the Stop a Running HC908 Target.pdf
application note that is available from P&E Microcomputer Systems website:
www.pemicro.com.
Target MCU Security Bytes
In ICS mode, the user's code is simulated on the PC, and not run from the Non-Volatile
memory of the device. Therefore, there is no need to pass security in this mode of
operation.
IGNORE Security Failure and Enter Monitor
Mode
Use this checkbox to cause the software to ignore a failure to properly pass the M68HC08
security check. If the checkbox is set, the software attempts to establish monitor mode
communications regardless of the security status. As long as the Baud and Port are correct,
and the device has been properly powered, this allows monitor mode entry. By ignoring
the security check failure you may still use monitor mode, but the ROM/Flash is not
accessible.
NOTE If a connection is not established for any reason other than security failure, the
connection dialog box always appears.
STATUS Area
The status area of the P&E Connections Manager window consists of one status string
following the Status: label, and seven items which list the state of the last attempt to
connect to a target and pass security. The description for these items is as follows:
• 0 – ICS Hardware loopback detected:
Every ICS or board which supports MON08 has a serial loopback in hardware
which, by connecting the transmit and receive lines, automatically echoes characters
from the PC. A valid character transmitted from the PC is echoed once by the
loopback circuitry on the board and once by the monitor of the target processor itself.
![](asset-164.png)
ICS MON08 Interface Connection
Connection Procedure
356
Microcontrollers Debugger Manual
This status indicates whether or not the first echoed character from the hardware
loopback was received when one of the security bytes was transmitted. If the status is
‘N’, which indicates that the character was not received, it is most likely due to one
of the following reasons:
– Wrong Com Port specified.
– The baud rate specified was incorrect (probably too low).
– The ICS/Target is not connected.
– No Power to the ICS.
If this status bit returns an ‘N’, you must correct this before analyzing the reset of the
status bits.
•1 – Device echoed some security bytes:
The monitor resident in a M68HC08 device automatically echoes every incoming
character when it is in monitor mode. A valid character transmitted from the PC is
echoed once by the loopback circuitry on the board and once by the monitor of the
target processor itself. This status indicates whether or not the second echoed
character from the monitor response was received when one of the security bytes was
transmitted. If the status is ‘N’, which indicates that the character was not received,
or not received properly, it is most likely due to one of the following reasons:
– The baud rate specified was incorrect.
– The part did not start the monitor mode security check on reset. Signals to force
monitor mode may be incorrect.
– No Power to the ICS.
If this status bit returns an ‘N’, you must correct this before analyzing the reset of the
status bits.
•2 – Device echoed all security bytes:
To pass security, the software must send eight security bytes to the processor. The
processor echoes each of these eight bytes twice. If all eight bytes did not get the
proper two-byte echo, this flag returns an ‘N’. Reasons for this include:
– The part did not start the monitor mode security check on reset. Signals to force
monitor mode may be incorrect.
– The baud rate specified was incorrect.
– The processor was not reset properly. Check the Target Hardware Type and if
you are connecting to a class II board, check the MON08 cable communication
connections type in the Advanced Settings dialog box.
•3 – Device signaled monitor mode with a break:
Once the processor has properly received the eight bytes from the PC software to
complete its security check, it transmits a break character to the PC signaling entry
into monitor mode. This break character is sent regardless of whether the security
![](asset-165.png)
ICS MON08 Interface Connection
Connection Procedure
357
Microcontrollers Debugger Manual
check was successfully passed. If a break character is not received from the
processor, this flag returns an ‘N’. Reasons for this include:
– The baud rate specified was incorrect.
– The processor was not reset properly. Check the Target Hardware Type. If you
are connecting to a class II board, check the MON08 cable communication
connections type in the Advanced Settings dialog box.
•4 – Device entered monitor mode:
Once the software receives, or fails to receive, a break character from the processor,
it attempts to communicate with the monitor running on the M68HC08 processor. It
tries to read the monitor version number by issuing a monitor mode read. If the
processor fails to respond properly to this command, this flag returns an ‘N’.
•5 – Reset was Power-On Reset:
If the device properly entered monitor mode (4), the software reads the reset status
register (RSR). This read does not affect the security sequence, and occurs purely for
diagnostic reasons. The RSR indicates the conditions under which the processor
underwent the last reset. For the software to pass the security check properly, it
MUST first cause the processor to undergo a Power-On Reset. The software reads
the RSR to determine if the last reset was indeed caused by power-on. The result of
the RSR read is indicated in parentheses after the flag value. If the highest bit is not
set then the reset was not a power-on reset, and the flag indicates an ‘N’. Reasons for
this include:
– The processor did not power all the way down because power was being supplied
to the processor through either the port pins, IRQ line, RESET line, or power
pins.
– The voltage driven on the power pin of the processor did not go below 0.1 volts.
– The processor was not reset properly. Check the Target Hardware Type. If you
are connecting to a class II board, check the MON08 cable communication
connections type in the Advanced Settings dialog box.
•6 – ROM is accessible (un-secured):
If the device properly entered monitor mode (4), the software reads locations $FFF6-
$FFFF to determine if the processor passes the security check. Memory locations
which are invalid or protected read back from the device as $AD. If all bytes from
$FFF6-$FFFF read a value of $AD, it is assumed the device is secure, and the flag
value is an ‘N’. If all flags 0-5 register a value of ‘Y’ and flag 6 register a value of
‘N,’ then the reset process has gone correctly except that the security code used to
pass security was incorrect. Specify the correct security code and try again, or
IGNORE the security failure and erase the device. Once you erase a secured device,
you must exit the software and restart it in order to pass security.

Device Class Description
The following device information summarizes the different classes of boards available to
the user. Detailed information about specific devices is available from Freescale.
Class 1 Device
ICS Board with processor installed. This is the standard and most common configuration
of the ICS08 boards. In this configuration, the processor is resident in one of the sockets
on the ICS board itself. The processor can be debugged and programmed in this
configuration, and an emulation cable containing all the processor I/O signals can be
connected to the user's MCU development board. In this configuration, the ICS board
hardware can automatically power up and down the processor in order to pass security in
the simplest fashion. The user has to be sure not to provide power from the MCU
development board, up through the emulation cable, to the processor pins themselves,
when this dialog box appears. This is so that the software, when attempting to establish
communications, can fully power the processor down. The software running on the PC
controls power to the user’s MCU development board via the serial port DTR line.
![](asset-16a.png)
ICS MON08 Interface Connection
Device Class Description
362
Microcontrollers Debugger Manual
Class 2 Device
ICS Board without processor, connected to the user’s microprocessor system via MON08
Cable. In this configuration, there is no processor resident in any of the sockets of the ICS
board itself. The processor is mounted down in the user’s MCU system. The connection
from the ICS board to the user’s MCU system is accomplished via the 16-pin MON08
connector. In this configuration, since the ICS does not control power to the processor, the
user is prompted to turn the processor's power supply on and off. Turning off the power
supply is necessary to pass the initial security mode check and access the Flash on the
processor. A simple reset is not enough; to pass the security check, you must first force the
processor to encounter a POR (power-on reset) which requires that the processor's voltage
dip below 0.1v. Once security is passed, resetting the device or re-entering the software is
easier.
Class 3 Device
Custom Board (no ICS) with MON08 serial port circuitry built in. In this configuration,
the ICS board is not used at all. The user must provide a serial port connection from the
PC, and provide all hardware configuration necessary to force the processor into MON08
mode upon reset. This includes resets both internal and external to the processor. In this
configuration, because the software does not directly control power to the processor, the
user is prompted to turn the processor's power supply on and off. The user is also
prompted to turn power on and off to reset the microprocessor, as the PC has no control of
the microprocessor reset. Turning off the power supply is necessary to pass the initial
security mode check and access the Flash on the processor. A simple reset is not enough;
to pass the security check, you must first force the processor to encounter a POR (power-
on reset) which requires that the processor's voltage dip below 0.1v. Once security is
passed, resetting the device or re-entering the software is easier. Class 3 selection also
applies to use of the ICS board with the two-pin blank part programming connector.
Class 4 Device
Custom Board (no ICS) with MON08 serial port circuitry and additional auto-reset circuit
built in. In this configuration, the ICS board is not used at all. The user must provide a
serial port connection from the PC and all hardware configuration necessary to force the
processor into MON08 mode upon reset. In addition, the user must include an extra circuit
which allows the reset line of the processor to be driven low from the DTR line of the
serial port connector (Pin 4 on a DB9). The following diagram shows the additional
connection needed to reset from a DB9 serial connector.

Tpd And Tpu Timing Textboxes
Tpd and Tpu set the power-down and power-up delay that is observed when power-
cycling a target for entry into Monitor Mode. These settings are only valid for devices
with automatically controlled power.
Whenever power is automatically switched off, or is manually requested to be switched
off, the software waits for an amount of time equal to the Tpd delay time before
proceeding to the connection protocol. This is because a board or power supply may have
capacitance which holds the power up for a short time after the supply has been switched

On reset is to occur.
Whenever power is automatically switched on, or is manually requested to be switched on,
the software waits for an amount of time equal to the Tpu delay time before attempting to
contact the 68HC08 processor. This is to allow time not only for power to be fully
available, but to wait until any reset driver has finally released the RESET line.

Target MCU Security Bytes
One of the steps that is necessary to properly bypass security is to provide the proper
security code for the information that is programmed into the part. This holds true even
when the part is blank. The security code consists of the 8 values, which are currently
stored in Flash locations $FFF6 - $FFFD of the processor.

NOTE If a connection is not established for any reason other than security failure, the

STATUS Area
The status area of the P&E Connections Manager window consists of one status string
following the Status: label, and seven items which list the state of the last attempt to
connect to a target and pass security. The description for these items is as follows:
• 0 – ICS Hardware loopback detected:
Every ICS or board which supports MON08 has a serial loopback in hardware
which, by connecting the transmit and receive lines, automatically echoes characters
from the PC. A valid character transmitted from the PC is echoed once by the
loopback circuitry on the board and once by the monitor of the target processor itself.
This status indicates whether the first echoed character from the hardware loopback
was received when one of the security bytes was transmitted. If the status is ‘N’,
which indicates that the character was not received, it is most likely due to one of the
following reasons:
– Wrong Com Port specified.
– The baud rate specified was incorrect (probably too low).
– The ICS/Target is not connected.
– No Power to the ICS.
If this status bit returns an ‘N’, you must correct this before analyzing the rest of the
status bits.
• 1 – Device echoed some security bytes:
The monitor resident in a M68HC08 device automatically echoes every incoming
character when it is in monitor mode. A valid character transmitted from the PC is
echoed once by the loopback circuitry on the board and once by the monitor of the
target processor itself. This status indicates whether the second echoed character
from the monitor response was received when one of the security bytes was
transmitted. If the status is ‘N’, which indicates that the character was not received,
or not received properly, it is most likely due to one of the following reasons:
– The baud rate specified was incorrect.
– The part did not start the monitor mode security check on reset. Signals to force
monitor mode may be incorrect.

processor echoes each of these eight bytes twice. If all eight bytes do not get the
proper two-byte echo, this flag returns an ‘N’. Reasons for this include:
– The part did not start the monitor mode security check on reset. Signals to force
monitor mode may be incorrect.
– The baud rate specified was incorrect.
– The processor was not reset properly. Check the Target Hardware Type and, if
you are connecting to a class II board, check the MON08 cable communication
connections type in the Advanced Settings dialog box.
• 3 – Device signaled monitor mode with a break:
Once the processor has properly received the eight bytes from the PC software to
complete its security check, it transmits a break character to the PC signaling entry
into monitor mode. This break is sent regardless of whether the security check was
successfully passed. If a break was not received from the processor, this flag returns
an ‘N’. Reasons for this include:
– The baud rate specified was incorrect.
– The processor was not reset properly. Check the Target Hardware Type. If you
are connecting to a class II board, check the MON08 cable communication
connections type in the Advanced Settings dialog box.
• 4 – Device entered monitor mode:
Once the software has received, or failed to receive, a break from the processor, it
attempts to communicate with the monitor running on the M68HC08 processor. It
tries to read the monitor version number by issuing a monitor mode read. If the
processor fails to respond properly to this command, this flag returns an ‘N’.
• 5 – Reset was Power-On Reset:
If the device properly entered monitor mode (4), the software reads the reset status
register (RSR). This read does not affect the security sequence, and occurs purely for
diagnostic reasons. The RSR indicates the conditions under which the processor
underwent the last reset. For the software to pass the security check properly, it
MUST first cause the processor to undergo a Power-On Reset. The software reads
the RSR to determine if the last reset was indeed caused by power-on. The result of
the RSR read is indicated in parentheses after the flag value. If the highest bit is not
set then the reset was not a power on reset, and the flag indicates an ‘N’. Reasons for
this include:

– The processor did not power all the way down because power was being supplied
to the processor through either the port pins, IRQ line, RESET line, or power
pins.
– The voltage driven on the power pin of the processor did not go below 0.1 volts.
– The processor was not reset properly. Check the Target Hardware Type. If you
are connecting to a class II board, check the MON08 cable communication
connections type in the Advanced Settings dialog box.
•6 – ROM is accessible (un-secured):
If the device properly entered monitor mode (4), the software reads locations $FFF6-
$FFFF to determine if the processor passes the security check. Memory locations
which are invalid or protected read back from the device as $AD. If all bytes from
$FFF6-$FFFF read a value of $AD, it is assumed the device is secure, and the flag
value is an ‘N’. If all flags 0-5 register a value of ‘Y’ and flag 6 registers a value of
‘N,’ then the reset process has occurred correctly except that the security code used
to pass security was incorrect. Specify the correct security code and try again, or
IGNORE the security failure and erase the device. Once you erase a secured device,
you must exit the software and restart it in order to pass security.

Debugging Limitations
The following limitations are inherent in MON08 debugging. Observe these restrictions
carefully.
1. Do not step a command that branches to itself.
2. Do not step a software interrupt (SWI) command.
3. The hardware breakpoint registers are reserved for use by the debugger. Attempting to
use these registers for other purposes may not work.
4. Be careful about showing peripheral status and data registers in the memory or
variables window. A refresh of the window reads these registers and may cause the
clearing of flags.
5. The debug monitor built into CPU08 processors uses up to 13 bytes of the stack. Do
not write to these addresses from (SP-13) to SP. To load a program into RAM, move
the stack to the end of RAM.
6. If interrupts are turned on during stepping, the debugger does not step into the
interrupt. Instead, it executes the whole interrupt and stops on the command following
the interrupt.
7. Do not set hardware breakpoints within the monitor ROM area itself. Hardware
breakpoints set in this area do not function properly.
Debugging Tips
The following tips may prove useful:
1. Single stepping is allowed in both RAM or ROM.
2. The first breakpoint set is always a hardware breakpoint, and any additional
breakpoints set are software breakpoints. To make sure that a hardware breakpoint is
being set, make sure only one breakpoint is being used.
3. Hardware breakpoints can stop execution in ROM or RAM. Software breakpoints can
stop execution only in RAM.
4. Experiment with the register interpreter. Use the View Register Files option in the
MultilinkCyclonePro menu.
5. Executing an SWI instruction while running is functionally equivalent to hitting a
breakpoint, except that execution stops at the instruction following the SWI.
6. A hardware breakpoint may be used to trap a data read/write to anywhere in the
memory map. The debugger stops at the instruction after the one that accesses the data
location.
7. When the target board is reset by the debugger, power to the microcontroller may be
turned off for a short duration. Although much of RAM may look the same, some
values may have changed.

Microcontrollers Debugger Manual
Device Class Description
The following device information summarizes the different classes of boards available to
the user. Detailed information about specific devices is available from Freescale.
Class 5 Device
P&E’s MON08 Cyclone Device connects to a PC via the serial port. The Cyclone-to-
MCU connection occurs via a standard 16-pin MON08 ribbon cable. The MON08
Cyclone Device allows the user to auto-detect the baud rate as well as auto-cycle the
power through the MCU system.
Class 7 Device
P&E MON08 Multilink and USB MON08 Multilink cables connect to the user’s MCU
system via a standard 16-pin MON08 ribbon cable. MON08 Multilink and USB MON08
Multilink allow one to auto-detect the baud rate as well as auto-cycle the power through
the microprocessor system.
Class 8 Device
P&E’s Cyclone Pro communicates with the PC through a Serial, Ethernet or USB port.
The Cyclone Pro can be used to debug and program the firmware inside of Freescale
HC08 microprocessors via a standard 16-pin MON08 ribbon cable. The Cyclone Pro can
provide its own power and clock signals to the microprocessor, as long as proper signals
are connected to the corresponding pins of the 16-pin MON08 header. In addition the
Cyclone Pro can be used for programming and debugging the HC08/HC12/HCS12
Freescale microprocessors via a standard 6-pin ribbon cable. To take advantage of this
functionality, connect proper signals to the standard 6-pin Background Debug Module
header.

HC08 ICS P&E Multilink/
Cyclone Pro Connections
In-Circuit Simulation (ICS) Mode is a P&E Microcomputer Systems mode of operation
that is a hybrid between In-Circuit Debugging and Full Chip simulation. P&E has
combined the benefits of each of these modes, while minimizing their respective
deficiencies.
ICS mode simulates the CPU core instructions on the user's PC. However, Inputs/Outputs
are read directly from the user's development device, and certain modules are run on the
actual device. Any instructions that affect an I/O location, for example, lda PORTA or
sta PORTA, also use data from the real device. This allows for all the benefits of full
chip simulation (Cycle by Cycle accuracy, unlimited breakpoints, and speed, to name just
a few), while allowing the obvious benefit of garnering relevant signals from actual
hardware.
In-Circuit simulation requires a user to have a connected MCU Device, be it a
development board, prototype hardware, or simply a device placed in a simple circuit on a
breadboard. Once connection is established, the P&E Interface loads a .MON file to the
microcontroller itself. This .MON file is the ICS-Kernel; it constantly runs on the device,
and interacts with the P&E software to provide information about changing I/O and any
peripherals that are running on the device itself.
The following modules are run on the actual device when in ICS mode, and as such their
Simulation commands become unnecessary, and therefore do not function:
I/O ports, SCI, SPI, IRQ, ADC, LCD, KBI.
All other modules function as fully simulated modules. For information about relevant
simulation commands, see the HC08 Full Chip Simulation section.

Tpu and Tpd Timing Textboxes
Tpu and Tpd set the power-up and power-down delay (respectively) that is observed when
power-cycling a target for entry into Monitor Mode. These settings are only valid for
devices with automatically controlled power.
Whenever power is automatically or manually switched off, the software waits for an
amount of time equal to the Tpd delay time before proceeding to the connection protocol.
This is because a board or power supply may have capacitance which holds the power up
for a short time after the supply has been switched off, but the supply voltage must reach
less than 0.1v before it is turned back on if a Power-On reset is to occur.
Whenever power is automatically or manually switched on, the software waits for an
amount of time equal to the Tpu delay time before attempting to contact the M68HC08
processor. This is to allow time not only for power to be fully available, but to allow all
reset drivers to release the RESET line.
Target has RESET Button
In using Class III boards, the software occasionally needs to get control of the target. For a
more detailed description of device classes, see Device Class Description. On systems
which are Class III boards with the monitor mode circuitry built-in (including RS-232
driver), there is no means to reset the target to gain control. If the board has a reset button,
the software can use this to gain control of the target system. If this option is checked, the
software prompts the user to push the target reset button when a reset of the target system
is desired. If the option is unchecked, the software prompts the user to power cycle the
target system to achieve a reset.
MON08 Cable Connection Communications Type
This selection box is valid only for Class II hardware configurations using the MON08
cable. It allows the user to specify the sequence that the software uses to power up the ICS
system. For a more detailed description of device classes, see Device Class Description.
When the software tries to create a power-on reset condition, two events must occur:
1. Power of the target MCU must go below 0.1v. This means that the processor cannot be
receiving power from its power pins, nor can it have a significant voltage being driven
on port pins or the IRQ line, as these drive the MCU power back through these pins. It
is crucial, therefore, to have the ICS and the Target both powered down at some point
in time.
2. The processor MON08 configuration pins, including IRQ, must be properly driven
when the target processor resets to drive it into monitor mode. If these pins are not set
up properly before the processor powers up, the processor may start up in user mode.

Power Up/Down Radio Buttons
Power Down ICS prompts the user to power down the board. Power Up ICS prompts the
user to power up the board.
This is the default option and works for most, if not all, ICS08/Target Board solutions.
1. Software automatically powers down the ICS.
2. Software asks the user to power down the board as follows:

3. Software automatically powers up the ICS, which configures the processor’s MON08
configuration pins.

Cycle Power Up/Down Radio Buttons
Cycle Power ICS asks the user to power cycle the board.
This option works for many ICS boards as well, but relies on the fact that while the ICS is
powered off, it holds the target in reset until it is powered up itself and has configured the
MON08 configuration pins. The sequence of events in this mode is:
1. Software automatically powers down the ICS.
2. Software asks the user to power cycle their board as follows:
Figure 15.9 Power Cycle Dialog Box
3. Software automatically powers up the ICS, which configures the processors MON08
configuration pins.
Target MCU Security Bytes
In ICS mode, the user's code is simulated on the PC, and not run from the Non-Volatile
memory of the device. Therefore, there is no need to pass security in this mode of
operation.
STATUS Area
The status area of the P&E Connection Manager window consists of one status string
following the Status: label, and seven items which list the state of the last attempt to
connect to a target and pass security. The description for these items is as follows:
• 0 – ICS Hardware loopback detected:
Every ICS or board which supports MON08 has a serial loopback in hardware
which, by connecting the transmit and receive lines, automatically echoes characters
from the PC. A valid character transmitted from the PC is echoed once by the
loopback circuitry on the board and once by the monitor of the target processor itself.
This status indicates whether or not the first echoed character from the hardware
loopback was received when one of the security bytes was transmitted. If the status is
![](asset-184.png)
HC08 ICS P&E Multilink/Cyclone Pro Connections
Connection Procedure
388
Microcontrollers Debugger Manual
‘N’, which indicates that the character was not received, it is most likely due to one
of the following reasons:
– Wrong Com Port specified.
– The baud rate specified was incorrect (probably too low).
– The ICS/Target is not connected.
– No Power to the ICS.
If this status bit returns an ‘N’, you must correct this before analyzing the rest of the
status bits.
• 1 – Device echoed some security bytes:
The monitor resident in an M68HC08 device automatically echoes every incoming
character when it is in monitor mode. A valid character transmitted from the PC is
echoed once by the loopback circuitry on the board and once by the monitor of the
target processor itself. This status indicates whether or not the second echoed
character from the monitor response was received when one of the security bytes was
transmitted. If the status is ‘N’, which indicates that the character was not received,
or not received properly, it is most likely due to one of the following reasons:
– The baud rate specified was incorrect.
– The part did not start the monitor mode security check on reset. Signals to force
monitor mode may be incorrect.
– No Power to the ICS.
If this status bit returns an ‘N’, you must correct this before analyzing the rest of the
status bits.
•2 – Device echoed all security bytes:
In order to pass security, the software must send eight security bytes to the processor.
The processor echoes each of these eight bytes twice. If all eight bytes did not get the
proper two-byte echo, this flag returns an ‘N’. Reasons for this include:
– The part did not start the monitor mode security check on reset. Signals to force
monitor mode may be incorrect.
– The baud rate specified was incorrect.
– The processor was not reset properly. Check the Target Hardware Type and if
you are connecting to a class II board, check the MON08 cable communication
connections type in the Advanced Settings dialog box.
•3 – Device signaled monitor mode with a break:
Once the processor has properly received the eight bytes from the PC software to
complete its security check, it transmits a break character to the PC signaling entry
into monitor mode. This break character is sent regardless of whether the security

– The baud rate specified was incorrect.
– The processor was not reset properly. Check the Target Hardware Type. If you
are connecting to a class II board, check the MON08 cable communication
connections type in the Advanced Settings dialog box.
•4 – Device entered monitor mode:
Once the software has received, or failed to receive, a break from the processor, it
attempts to communicate with the monitor running on the M68HC08 processor. It
tries to read the monitor version number by issuing a monitor mode read. If the
processor fails to respond properly to this command, this flag returns an ‘N’.
•5 – Reset was Power-On Reset:
If the device properly entered monitor mode (4), the software reads the reset status
register (RSR). This read does not affect the security sequence, and occurs purely for
diagnostic reasons. The RSR indicates the conditions under which the processor
underwent the last reset. For the software to pass the security check properly, it
MUST first cause the processor to undergo a Power-On Reset. The software reads
the RSR to determine if the last reset was indeed caused by power-on. The result of
the RSR read is indicated in parentheses after the flag value. If the highest bit is not

– The voltage driven on the power pin of the processor did not go below 0.1 volts.
– The processor was not reset properly. Check the Target Hardware Type. If you
are connecting to a class II board, check the MON08 cable communication
connections type in the Advanced Settings dialog box.
•6 – ROM is accessible (un-secured):
If the device properly entered monitor mode (4), the software reads locations $FFF6-
$FFFF to determine if the processor passes the security check. Memory locations
which are invalid or protected read back from the device as $AD. If all bytes from
$FFF6-$FFFF read a value of $AD, it is assumed the device is secure, and the flag
value is an ‘N’. If all flags 0-5 register a value of ‘Y’ and flag 6 register a value of
‘N,’ then the reset process has gone correctly except that the security code used to
pass security was incorrect. Specify the correct security code and try again, or
IGNORE the security failure and erase the device. Once you erase a secured device,
you must exit the software and restart it in order to pass security.

SofTec HC08 Connection
This section guides you through the first steps toward debugging with the CodeWarrior
IDE and the SofTec HC08 connection. It does not replace all the additional documentation
provided in this manual, but gives you a good starting point.
SofTec HC08 Technical Considerations
The 8/16 bits debugger (and then the CodeWarrior IDE) might be connected to HC08
hardware using the SofTec HC08.
When the debugger runs the SofTec HC08 connection, it can communicate and debug
HC08-based hardware connected through the SofTec in-circuit debugger/programmer
units, such as the SofTec Microsystems HC08 ISP Debuggers/Programmers (inDART
Series) and Starter Kits (AK/SK/PK/ZK and newer Series).
Refer to the inDART®-HC08 In-Circuit Debugger/Programmer for Motorola HC08
Family FLASH Devices User’s Manual from SofTec for communication hardware
requirements and SofTec product installation.
CodeWarrior IDE and SofTec HC08
Connection
There are two separate paths that may be followed to take the first steps toward debugging
with the CodeWarrior IDE and the SofTec inDART-HC08 connection. The differences
between the two paths hinge on the starting point for the steps:
• Using the Stationary Wizard at the start of the project
• From within an existing project

Setting Up the FSICEBASE System
The Freescale In-Circuit Emulator Base (FSICEBASE) development system includes
cables and software. You need to connect the cables and install the software in order to use
the FSICEBASE. This section contains the following topics to help you set up the system:
•Setting Up the Hardware
•Establishing Communication
Setting Up the Hardware
This section explains how to connect a host computer to the Freescale In-Circuit Emulator
Base (FSICEBASE). There are three ways to connect a host computer to the FSICEBASE:
• Directly from the USB port of a host computer to the FSICEBASE USB port
• Directly from the ethernet port of a host computer to the FSICEBASE ethernet port
• From the host computer, through a Local Area Network (LAN), to the FSICEBASE
ethernet port
Connect the FSICEBASE to a host computer in one of the three ways described in the
following paragraphs.
1. If you are using an ethernet connection to connect your host computer to the
FSICEBASE through a Local Area Network (LAN):
a. Connect host computer to LAN
b. Connect FSICEBASE to LAN
c. Make sure power supply is not connected to board
d. Connect one end of ethernet cable to ethernet port of FSICEBASE (make sure to
use the straight-through ethernet cable when connecting to LAN)
e. Connect other end of ethernet cable to Local Area Network (LAN)
NOTE To complete the connection through a LAN, obtain the IP address, subnet
mask, and default gateway information from your network administrator. This
information is used in a later step.
2. If you are using an ethernet connection to connect your host computer directly to the
FSICEBASE (not through a LAN):
a. Make sure power supply is not connected to board
b. Connect one end of ethernet cable to ethernet port of FSICEBASE (make sure to
use the cross-over ethernet cable when connecting directly to a Network Interlace
Card (NIC))
![](asset-196.png)

Specifying the Clock Speed
The FSICEBASE platform board can supply an oscillator clock source for the MCU’s
OSC1 input. Note that many emulator modules (EMs) require a specific jumper
configuration so that this clock source can be used. Refer to the specific EM user's manual
for EM clock source information.
The FSICEBASE has seven clock frequencies available: six internally generated clock
frequencies (32 MHz, 16 MHz, 8 MHz, 4 MHz, 2 MHz, and 1 MHz) and an external clock
source. You can also define a custom internal clock speed.
If you use an external clock source, you need to use a logic clip to connect the clock to the
FSICEBASE. You must use logic clip A. Use the white wire to connect to the external
clock.
To specify the clock speed:
1. Start the debugger — the True-time Simulator & Real-time Debugger window
appears.
For more information see Starting the Debugger.
2. From debugger main menu, select FSCICEBASE-HC08

clock is connected externally, on a connected emulator module (EM), or FSICE
Generated.
5. Specify clock speed if internally generated
a. If you selected FSICE Generated, select the clock speed to be emulated
b. If you selected Custom, type clock speed in Custom text box
NOTE If you specify a custom clock speed, be aware that the FSICEBASE can
provide clock speeds from 4100Hz to 40MHz in steps of 5kHz. The
FSICEBASE uses a clock synthesis chip to generate the clock speed. This
method is not as accurate as a crystal: only within about 0.75% absolute
frequency with about 5% jitter. If you choose a clock value (either from one of
the radio buttons or by typing it in) that is an integer divisor of 32MHz or
9.8304MHz, you get an accurate crystal-sourced clock.
6. Click OK
The debugger instructs the FSICEBASE to use new clock information. The Command
window (Figure 17.9) of the debugger shows confirmation message.

Bus State Analyzer (BSA)
421
Microcontrollers Debugger Manual
Bus State Analyzer (BSA)
The bus state analyzer (BSA) shows the logical state of the target MCU bus. The BSA
takes a snapshot of the MCU bus. It also captures the signals from the logic clips of Pods
A, B, and C of the FSICEBASE (24 lines in total). This capturing of data enables you to
determine what is occurring in a system without actually disturbing the system.
At the end of each MCU clock cycle, the BSA takes a snapshot of the logical states of the
target MCU bus. The analyzer stores the snapshots in the trace buffer, according to its
mode. (This action is known as storing cycles.)
NOTE This analyzer is a bus state analyzer. It does not show signal hold or setup
times.
To start using the BSA, you need to define patterns of logical states as events (or terms).
You also need to specify the analyzer mode: continuous, counted, or any of five sequential
modes. This determines which cycles the analyzer stores.
Data collection (cycle storage) begins when you arm the analyzer and start program
execution. Data collection continues until execution stops, through a specified number of
events, or through a defined sequence of events.
Using BSA
To use the bus state analyzer (BSA) to produce useful data that you can view and analyze,
you must:
1. Define events (terms).
2. Arm the BSA.
Defining Events
You define an event by specifying a combination of criteria. You can define the criteria to
be particular values in certain addresses, read or write access on an instruction or on data,
extended address access, or signals sent through one of the five logic clips that you can
connect to Pod A of the FSICEBASE.
The Bus State Analyzer uses the criteria that you specify to create an event, and labels the
event A, B, C, or D. When the BSA determines that the criteria of a certain event has been
met, depending on the triggering mode, it records the data that is in the bus of the MCU at
that particular clock cycle. It also records the data that is in the lines of Pods A, B, and C.
You can control the way that the BSA records this information by specifying a recording
mode.
![](asset-1a6.png)
HC08 FSICEBASE Emulator
Bus State Analyzer (BSA)
422
Microcontrollers Debugger Manual
To define an event:
1. Start the debugger
2. Load the program to debug
a. If you launched the debugger from a project in the CodeWarrior IDE, the debugger
automatically loads the program (.abs or .elf file)
b. If the debugger has not loaded the program that you want to debug:
• From the debugger main menu, select File > Load Application
• Specify the location of the executable program file (.abs or .s19 file)
• Click Open — debugger loads the application you specified
3. From debugger main menu, select FSCICEBASE-HC08
The FSICEBASE-HC08 menu is between the Run menu and the Component menu. If
you do not see the FSICEBASE-HC08 menu, you need to specify the connection. For
more information on specifying a connection see Specifying A Connection.
4. Select Bus Analyzer Configuration — Bus Analyzer Configuration dialog box opens
(Figure 17.10)
Figure 17.10 Bus Analyzer Configuration Dialog Box
![](asset-1a7.png)
HC08 FSICEBASE Emulator
Bus State Analyzer (BSA)
423
Microcontrollers Debugger Manual
5. Select Term or Range
A range consists of two 32-bit values. Range does not refer to a range of addresses. If
you define an event as a range, the BSA triggers every time the input falls between the
range starting term (the first 32-bit value) and the range ending term (the second 32-bit
value).
6. In Address area, specify the address(es) that the BSA monitors
7. In Data area, specify the data that the BSA monitors
8. In Access area, specify the type of access that you want the BSA to monitor
9. In Type area, specify whether the you want the BSA to record data, instructions or any
kind of value at the specified address
10. Specify Pod A signals (logic clips attach to pins of Pod A) that you want the BSA to
monitor for this event
NOTE You can use five of the pod A logic clips to define an event. The other signals
of Pod A, and the signals of Pods B and C cannot be used to define an event.
The Bus Analyzer Configuration dialog box shows the five clips that you can
use to trigger an event. The choice of these five signals is hard-set in the
FSICEBASE; you cannot choose other signals to be used as event criteria.
However, the BSA does capture data from all 24 lines of Pods A, B, and C.
11. If you want the term to also act as a breakpoint, check the Breakpoint checkbox.
12. Specify the Recording Mode
• For information about the recording mode, see Recording Modes.
• If you check the Stop when recording completes checkbox, the debugger stops
program execution when bus state analyzer recording is done.
13. Specify the Time Tag Clock Frequency
14. Click Save to apply the event information to the current debug session and close the
dialog box. The BSA uses the terms when you arm the BSA.
15. Click Save to save the event information to a file.
16. Click Arm to ready the BSA to collect data.
The BSA does not start collecting data until execution begins. The debugger indicates
that the BSA is armed by showing the word Armed in the status bar.

Microcontrollers Debugger Manual
Recording Modes
When you define an event, you can specify the recording mode that the Bus State
Analyzer uses to collect data. This section explains how the different modes work.
Continuous: All Cycles
After execution begins, the trace buffer begins storing data from the first cycle. This
continues until execution arrives at a breakpoint, or until you halt execution.
Continuous: Events Only
After execution begins, the trace buffer begins storing data when data matches an event
definition. This continues until execution arrives at a breakpoint, or until you halt
execution.
Counted: All Cycles
After execution begins, the trace buffer begins storing data after the specified number of
cycles from first cycle. A breakpoint can stop storage before the analyzer stores the
specified number of cycles, as can halting execution.
Counted: Events Only
After execution begins, the trace buffer begins storing data that matches an event
definition for the specified number of cycles. A breakpoint can stop storage before the
analyzer stores the specified number of cycles; as can halting execution.
A+B+C+D
After execution begins, the trace buffer begins storing data from the first cycle run. This
continues through the occurrence of event A, B, C, or D (whichever is enabled); data
storage ends after the specified number of post-trigger cycles.
A+B -> C+D
After execution begins, the trace buffer begins storing data from the first cycle. This
continues through the occurrence of two events: A or B, followed by C or D. Data storage
ends after the specified number of post-trigger cycles.
If you select this mode, you must enable event A, event B, or both. You must enable event
C, event D, or both. Otherwise, the bus state analyzer cannot be triggered.
A -> B -> C !D
After execution begins, the trace buffer begins storing data from all cycles. This continues
through the occurrence of three events, A, B, and C, in order, if event D does not occur. (If
![](asset-1a9.png)
HC08 FSICEBASE Emulator
Bus State Analyzer (BSA)
425
Microcontrollers Debugger Manual
D occurs, the sequencer starts again looking for event A.) Data storage ends after the
specified number of post-trigger cycles.
If you select this mode, you must enable events A, B, and C. Otherwise, the bus state
analyzer cannot be triggered. If you disable event D, you convert this mode to a simple,
three-event sequence.
A -> B -> C -> D
After execution begins, the trace buffer begins storing data from all cycles. This continues
through the occurrence of four events, A, B, C, and D, in order. Data storage ends after the
specified number of post trigger cycles.
If you select this mode, you must enable all four events A, B, C, then D. Otherwise, the
bus state analyzer cannot be triggered.
Nth Event: A+B+C+D
After execution begins, the trace buffer begins storing data from N occurrences of cycles
that match the definitions of events A, B, C, or D (whichever are enabled). Then the bus
state analyzer captures the next 4096 cycles.
By selecting the terminal post trigger count, the user can control the number of cycles that
is stored. This can be used to speed uploading of the BSA data if only a small portion of
data is needed.
NOTE The terminal count or post trigger cycles are valid only for counted or
sequential modes. For a counted mode, this field specifies the number of cycles
to be stored. For a sequential mode, this field specifies the number of cycles to
be stored after the trigger sequence occurs.
Time Tag Clock Frequency
An optional part of analyzer setup is specifying the frequency and source of the time tag
clock. This clock provides a time reference value in each frame of the trace buffer. To
select the clock frequency, see Defining Events.
You can select from the following frequencies:
• 32 Mhz Selects the 32 MHz oscillator.
• 16 Mhz Selects the 16 MHz oscillator.
• 8 Mhz Selects the 8 MHz oscillator.
• 4 Mhz Selects the 4 MHz oscillator.
• 2 Mhz Selects the 2 MHz oscillator.
• 1 Mhz Selects the 1 MHz oscillator.
![](asset-1aa.png)
HC08 FSICEBASE Emulator
Bus State Analyzer (BSA)
426
Microcontrollers Debugger Manual
• External Selects the external clock
• Custom selects the programmable clock.
• Bus Clock selects the emulator clock, the bus clock of the emulating MCU.
If you select External, make sure to connect the TT_OSC clip (white) of the pod B cable to
the external clock source.
NOTE If you specify a custom clock speed, be aware that the FSICEBASE can
provide clock speeds from 4100Hz to 40MHz in steps of 5kHz. The
FSICEBASE uses a clock synthesis chip to generate the clock speed. This
method is not as accurate as a crystal: only within about 0.75% absolute
frequency with about 5% jitter. If you choose a clock value (either from one of
the radio buttons or by typing it in) that is an integer divisor of 32MHz, you get
an accurate crystal-sourced clock.
Collecting Bus Data
To instruct the Bus State Analyzer (BSA) to start collecting data:
1. From debugger main menu, select FSCICEBASE-HC08
2. Select Arm Trace — the BSA begins to collect data when the debugger starts
execution of the loaded application. The BSA uses the events that you defined in the
Bus State Analyzer Configuration dialog box.
Viewing Data
You can view the data collected by the BSA in several formats. You can view: raw data,
disassembled instructions, mixed raw data and disassembled instructions, and source
code.
To view data:
1. From debugger main menu, select FSCICEBASE-HC08
2. Select Trace — the Trace window opens (Figure 17.11)

HCS08 Full Chip Simulation
Full Chip Simulation (FCS) does not involve real input and output. Because of this, it does
not require a target device to be connected to your PC. The HCS08FCS connection
simulates the execution of code on the user’s MCU system, including the function of any
peripherals associated with the device that you select. For more detailed information, refer
to the Full Chip Simulation description for the module that you are using.
Configuration Procedure
To select Full Chip Simulation as the debugger connection:
1. Choose the Full Chip Simulation option from the set connection dialog box. See
Figure 18.1.
2. Click the OK button.

Device Option
The Device selection of the HCS08FCS menu allows the user to select the particular
Freescale processor that they wish to use. When choosing the Device option from the
HCS08FCS menu, extended menus open which allow you to select the family (e.g. GB
Family), and device type (e.g. 9S08GB60) of the MCU that you are using.
Figure 18.3 HCS08FCS Device Extended Menus
Full Chip Simulation Module Commands
The HC08FCS Menu contains the Full Chip Simulation commands for the modules that
have specialty commands associated with them for a chosen device. For more information
about specific module commands refer to the Full Chip Simulation section describing the
module.
Run Till Cycle Command
The Run Till Cycle command begins code execution, and stops execution when the
specified cycle count is reached. Note that the parameter given is not the number of cycles
to execute, but the total cycle count of the simulator (displayed in the Register Window).
Use this command to verify specific timings of a given event; run until a given event is
complete, or before it completes, to step through the event itself; or in any application
where cycle-timed execution is desired.
Initialize Input Ports On Startup
The Initialize Input Ports on Startup option initializes all simulated inputs to $00 when
you start the software, or when you switch the Device Mode or Debug Target. This

initialization does not apply to a reset command. When you change this option, the new
state takes effect the next time you start HiWave (or switch Device Mode/Debug Target).
View Register Files Command
The View Register Files selection in the HCS08FCS menu also gives the user the option of
running the register file viewer/editor. If register files are available for the device that you
have chosen, the Choose a Register Block window (see Figure 18.4) opens. You may
also open it by entering the R command in the Command Window command line.
Figure 18.4 Choose A Register Block Dialog Box
If register files have been installed on the host computer, selecting a block brings up the
Register Block register listing (see Figure 18.5), which shows a list of the files, their
addresses, and their descriptions. This begins interactive setup of system registers such as
I/O, timer, and COP watchdog.
Figure 18.5 Timer Interface Module Register Listing
Selecting a file brings up the Register Window (see Figure 18.6), which displays the
values and significance for each bit in the register. The registers can be viewed and their
values modified, and the values can be stored back into debugger memory.

ADC Module
In Full Chip Simulation (FCS), this module simulates all functionality of the Analog to
Digital Conversion (ADC) module including data input on all ADC channels, flag polling,
interrupt operation as well as the bus and CGMXCLK reference clock sources. FCS mode
uses the buffered input structure to simulate the ADC inputs. The user can queue up to 256
data values. To queue the ADC Input Data, use the ADDI command in the command
prompt. If the data parameter is given, the value is placed into the next slot in the input
buffer. Otherwise, if no parameter is provided, a window is displayed with the input buffer
values. Input values can be entered while the window is open. An arrow points to the next
value to be used as input to the ADC. The conversion takes place after a proper value is
written to the ADC Status and Control register. Once the conversion occurs, the arrow
moves to the next value in the ADC Buffer.
Figure 18.8 ADC IN Buffer Display
At any point, use the ADCLR command to flush the input buffer for the ADC simulation.
After the conversion is complete, the first queued value is passed from the data buffer into
the ADC data register. It can be observed in the memory window by displaying the
memory location corresponding to the ADC data register.
Figure 18.9 Memory Component Window

437
Microcontrollers Debugger Manual
When the conversion is complete, the FCS sets the appropriate flag. If interrupts are
enabled, the Program Counter changes flow to the interrupt routine (as defined in the
vector space of the MCU). For more information on ADC configuration, refer to the
Freescale user manual for your microprocessor.
ADC Module Commands
The following commands are available for the M68HCS08 ADC Module.
ADDI Command
The ADDI command allows the user to input the data into the ADC converter. If a data
parameter is given, the value is placed into the next slot in the input buffer. Otherwise, if
no parameter is given, a window is displayed with the input buffer values. Input values can
be entered while the window is open. An arrow points to the next value to be used by the
ADC. The maximum number of input values is 256 bytes.
Syntax
>ADDI [<n>]
Where:
<n> The value to be entered into the next location in the input buffer.
Example
>ADDI $55
Set the next input value to the ADDI to $55
>ADDI
Pull up the data window with all the input values.
ADCLR
Use the ADCLR command to flush the input buffer for ADC simulation. This resets the
input data buffer and clears out all values. Notice that if the ADC is currently using a
value, this command does not prevent the ADC from using it. See ADDI command for
information on how to access the input buffer of the ADC interface.
Syntax

Clock Generation Module
In FCS, this module simulates all functionality of the Clock Generation Module (ICG),
including:
• Phase Locked Loop (PLL) generation
• Automatic lock detection
•Interrupt
• Acquisition
• Tracking
• Flag polling
FCS mode uses simulated External Oscillator Frequency change command (XTAL) to
allow the user to input the desired XTAL value. To check the current value of the External
Oscillator, Bus Frequency and CGMXCLK Frequency, open the HCS08FCS menu, then
select Clocks Module > Show MCU Clocks.

Once you select the MCU Clocks Menu, the Cycles Window displays all of the above-
mentioned Clock Frequencies.

Figure 18.11 Frequency Display
Once the ICG is properly configured, the user can monitor the status of the PLL by polling
the corresponding flag. If PLL interrupt is enabled, FCS jumps to an appropriate
subroutine, as long as the interrupt vector is properly defined. To observe the flag going up
as a result of the corresponding CPU event, situate your Memory Window on the memory
location of the ICG Status and Control register.
Figure 18.12 Memory Window
For more information on how to properly configure Clock Generation, refer to the
Freescale reference manual for your microprocessor.
Clock Generation Module Commands
The following commands are available for the M68HCS08 Clock Generation Module.
XTAL Command
Use the XTAL command to change the value of the simulated external oscillator. This in
turn affects the input to the PLL/DCO, and therefore the bus frequency. The P&E
simulator is a cycle-based simulator, so changing the XTAL value does not affect the
![](asset-1b8.png)
HCS08 Full Chip Simulation

Microcontrollers Debugger Manual
speed of simulation; it does, however, affect the ratio in which peripherals receive cycles.
Certain peripherals which run directly from the XTAL run at different speeds than those
that run from the bus clock.
Syntax
>XTAL <n>
Where:
•<n>, by default, is a hexadecimal number, representing the simulated frequency
of an external oscillator. Adding the suffix t to the n parameter forces the input
value to be interpreted as base 10.
Example
>XTAL
Brings up an input window. The default base for this input value is 10. However,
this value can be forced to a hexadecimal format through use of the suffix h.
Inter-Integrated Circuit Module
In FCS, this module simulates all functionality of the Inter-Integrated Circuit (IIC) module
including:
• Flag polling
• Interrupt enabled mode
• Transmission and reception of external data
• Master and slave modes of operation
• START and STOP signal generation detection
• Acknowledge bit generation detection
FCS mode uses the buffered input/output structure to simulate IIC inputs. The user can
queue up to 256 data bytes into the input buffer. The output buffer of the USB module can
also hold 256 output bytes. To queue the IIC Input Packets, use the IICDI <...>
command in the command prompt. For a more detailed description of the command, refer
to the IIC Commands section. If the IIC packet parameters are properly defined, the packet
is placed into the next slot in the input buffer. Otherwise, if no parameters are provided, an
IIC Input Buffer window is displayed.
The user can enter different IIC packet parameters while the window is open, including
START, STOP, ACK, NACK and data bytes. An arrow points to the next byte to be used
as input to the IIC. The data from the IIC input buffer is written to the IIC module registers
once the IIC module is turned on and properly configured for receiving data from an
external IIC device. Once simulation of the data transmission is over, the arrow moves to
the next value in the IIC Input Buffer.

Figure 18.13 IIC Input Buffer Display
The IIC data input/output log buffer simulation allows the user to gain access to the past
256 IIC data bytes that have been shifted in and out of the module. To bring up the IIC IN/
OUT LOG buffer dialog box, use the IICDO command.
Figure 18.14 IIC IN/OUT LOG Buffer Display
At any point, use the IICCLR command to flush the input as well as input/output log IIC
buffers.
After the IIC simulated input is received, the first queued-in data byte is passed from the
data buffer into the corresponding IIC module registers. It can be observed in the Memory
Window by displaying the appropriate register location there.

The user can also observe different IIC flags in the Memory Window. If you run the
module in Flag Polling mode, poll the flag corresponding to the expected IIC event. If the

IIC interrupts are enabled, the FCS jumps to an appropriate subroutine as long as the IIC
interrupt vectors are properly defined.
For more information on how to configure IIC module for desired operation, refer to the
Freescale user manual for your microprocessor.
Inter-Integrated Circuit Module Commands
The following commands are available for the M68HCS08 Inter-Integrated Circuit
Module.
IICDI Command
The IICDI command allows the user to input data into a buffer of data to shift into the IIC
module when it receives data from an external device. If a data parameter is given, the
value is placed into the next slot in the input buffer. Otherwise, if no parameter is given, a
window is displayed with the input buffer values. Input values can be entered while the
window is open. The maximum number of input values is 256.
This command is useful for either inputting response data from a slave target or for
inputting data packets from an external master. Note that when the microprocessor
attempts to read an acknowledge from an external device, and the next value in the buffer
is neither ACK nor NACK, the microprocessor automatically receives an ACK signal (i.e.
assumes ACK unless NACK is specified).
Syntax
>IICDI [<n>][START][STOP][ACK][NACK]
Where:
•<n> indicates the value to be entered into the next location in the input buffer
•START indicates the incoming START signal
•STOP indicates the incoming STOP signal
•ACK corresponds to ACK signal
•NACK corresponds to NACK signal
For a detailed description of the IIC protocol and a proper way to configure the IIC
module, refer to the Freescale user manual for your microprocessor.

Pulls up the data window with all the input values
>IICDI 22 33
This is an example of data being returned from a slave device. Once the MCU
transmits a start signal and the target address, it receives and ACK from the slave
device. An ACK is implied unless a NACK is specified via the IICDI command.
The next two data bytes read are 22 and 23. If the microprocessor attempts to read
another byte, it gets an $FF value followed by a NACK signal (NACK because
nothing remains in the input buffer). The receiving device then generates a STOP
signal. A more exact input from a device designed to return two bytes is:
>IICDI ACK 22 ACK 23 NACK
IIC in master mode transmits to a slave:
• If the slave device acknowledges all output bytes of the transmitting device,
there is no need to specify an input packet. If the master device is going to
transmit an address and two bytes, the following packet is equivalent to no
packet:
>IICDI ACK ACK ACK
• If, however, the slave receiver is designed to generate a NACK signal after the
second received data byte, the proper response packet is:
>IICDI ACK ACK NACK
• The address result being the first ACK, the first data result being the second
ACK, and the second data byte being the NACK.
IIC in MASTER mode is not acknowledged by any Slave:
>IICDI NACK
• If the NACK signal is entered before our master device transmits a START
signal, then the master device gets a NACK when it tries to read an
acknowledge after the address is output. The master device then generates a
STOP signal and releases the BUS.
IIC in SLAVE mode receives a Write from an external Master:
This example is for an external master which is writing to the microprocessor
configured to simulate the slave mode operation. The packet contains both START
and STOP signals which puts the simulated device into the slave mode.
>IICDI START 55 AA 22 STOP
This input adds five values to the input queue which is a packet from an external
master, including the following procedure values:
1. A start signal comes in
2. The address $55 comes, in specifying a write (slave receive). The Address
Register in the current simulated device has been previously set to $55

Module, including:
• programmable MTIM clock input
• free running or modulo up count operation
• flag polling
• interrupt enabled mode of operation

Serial Communications Interface Module
In FCS, this module simulates all functionality of the Serial Peripheral Interface (SPI)
module including:
• Flag polling
• Interrupt enabled mode
• 8- or 9-bit length data codes
• Odd and even parity modes
• Transmission and reception of external data
FCS mode uses the buffered input/output structure to simulate SCI inputs. The user can
queue up to 256 data values into the input buffer. The output buffer of the SCI module can
also hold 256 output values. To queue the SCI Input Data, use the SCDI <n> command
in the command prompt. If <n> (the data parameter) is given, the value is placed into the
next slot in the input buffer.
Otherwise, if no parameter is provided, a window is displayed with the input buffer
values. You can enter input values while the window is open. An arrow points to the next
value to be used as input to the SCI. The data from the SCI input buffer is written to the
SCI data register once the SCI module has been turned on and is properly configured for
receiving data from an external serial device. Once the simulation of the data transmission
is over, the arrow moves to the next value in the SCI IN Buffer.

Serial Peripheral Interface Module
In FCS, this module simulates all functionality of the Serial Peripheral Interface (SPI)
module including:
• flag polling
• interrupt enabled mode
• master and slave modes
• slave input clock
• transmission and reception of external data
FCS mode uses the buffered input/output structure to simulate SPI inputs. The user can
queue up to 256 data values into the input buffer. The output buffer of the SPI module can
also hold 256 output values. To queue the SPI Input Data, use the SPDI <n> command at
the command prompt. If <n> (the data parameter) is given, the value is placed into the
next slot in the input buffer.
Otherwise a window is displayed with the input buffer values. You can enter input values
while the window is open. An arrow points to the next input value to the SPI. The data
from the SPI input buffer is written to the SPI data register once the SPI module is turned
on and is properly configured for receiving data from an external serial device. Once the
simulation of the data transmission is over, the arrow moves to the next value in the SPI
IN Buffer.

interrupts are enabled, the FCS jumps to an appropriate subroutine as long as the SPI
channel interrupt vectors are properly defined.
To simulate the frequency of the SPI slave input clock, use the SPFREQ <n> command.
If the SPI is configured for slave mode, this command allows the user to enter the number
of cycles <n> in the period of the input clock. If the SPFREQ command is not used, then
clocking is set by the SPI control register.

In FCS, this module simulates all functionality of the Timer Interface module, including:
• Input capture/output compare
• Pulse width modulation
• Internal or external clock input
• Free running or modulo up count operation
• Flag polling
• Interrupt enabled mode of operation.
FCS mode uses the simulated port inputs to trigger the input capture on a given timer
channel. To define an input state of the specific port, use the INPUT<x> <n> command
in the Command line window. The <x> represents the corresponding I/O port, while <n>
stands for the input value to write to this port. At the same time, you can use the INPUTS
command to display the Simulated Port Inputs for all general IO ports. It displays the
current simulated values to all applicable input ports. See the documentation for Timer
Module Commands for more information about the various forms of this command.

Use the Simulated Port Inputs dialog box to reconfigure the input value to any I/O port.
Depending on whether the input capture is set for rising/falling edge, to trigger the event,
first set the port inputs high or low and then invert them to an opposite value. Once the
Input Capture event takes place, you can observe the CHxF in the Channel Status and
Control register in the Memory window.
Figure 18.37 Memory Component Window
If the Timer module is configured for an Output Compare event, then once the event takes
place you can observe the same CHxF Flag via the Memory window. If the timer channel
interrupt is enabled, the FCS jumps to an appropriate subroutine as long as the Timer
channel interrupt vector is properly defined. To observe the Timer Overflow Flag (TOF)
flag being set as a result of the corresponding CPU event, situate your Memory window on
the memory location of the Timer Status and Control register.
To observe the Pulse Width Modulation (PWM) operation, properly configure the Timer
to operate in the Modulo up count mode, choose the toggle-on-overflow or clear/set output
on compare events to create the desired duty cycle wave. Once a PWM event takes place,
you can observe pin toggle/clear/set behavior corresponding to the Timer configuration in
the Memory window displaying the IO port associated with a given timer channel.
To observe the accuracy of the Timer module operation, the user can observe the number
of CPU cycles that it takes for the event to occur. The cycle counter is only incremented as

Non-Volatile Memory Preservation
The user is given the option of preserving up to three independent ranges of non-volatile
memory (on devices with EEPROM, the entire EEPROM array may optionally be
preserved as well). Ranges that are designated as “preserved” are read before an erase, and
re-programmed immediately afterwards, thereby preserving the data in these ranges. Any
attempts to program data into a preserved range is ignored.
When entering an address into the preserved range field (hexadecimal input is expected),
the values are masked according to the row size of the device. This ensures that the
reprogramming of preserved data does not cause any program disturb conditions.

HCS08 Open Source BDM
Connection
This chapter guides you through the first steps toward debugging with the CodeWarrior
IDE and the HCS08 Open Source BDM connection. It does not replace all the additional
documentation provided in this manual, but gives you a good starting point.
HCS08 Open Source BDM Technical
Considerations
The 8/16 bits debugger (and then the CodeWarrior IDE) can be connected to HCS08
hardware using the HCS08 OSBDM (Open Source BDM) cable.
When the debugger runs the HCS08 Open Source BDM connection, it can communicate
and debug HCS08 core-based hardware connected through the Open Source BDM
Interface as described at the Freescale Semiconductor web site: http://www.freescale.com
(keyword: OSBDM08).
CodeWarrior IDE and HCS08 Open Source

HCS08 On-Chip DBG
Module
The HCS08 derivatives featuring an on-chip DBG module require a debugger graphical
user interface to setup this module and take full advantage of this enhanced debugging
feature. This chapter describes the debugger DBG module user interface.
Within several HCS08 debugger connections (e.g. P&E Debug), the HCS08 Serial
Monitor and inDART-HCS08, a complete graphical user interface is provided. A trigger
setup dialog box and context sensitive context menus (right-click) in the Source,
Assembly, Data and Memory component windows are used to set the on-chip DBG
module and triggers.
This DBG module support is automatically enabled or disabled, according to derivative
selected by user or automatically through the device Part Id.
Reference Document
The HCS08 on-chip DBG module described in this chapter is also described in the
HCS08RMv1/D, Rev. 1, 6/2003 Freescale document.
DBG Features
The debugger covers all features available within the on-chip DBG module:
• Regular hardware breakpoints and watchpoints
• Predefined preset Instruction Triggers, Memory Access Triggers or Capture
Triggers, a wide set of complex hardware breakpoints (triggers on program code
instructions) and watchpoints (triggers on device memory access) and data bus
recording
• Expert Triggers, as powerful as predefined preset triggers
• Code program flow rebuild from DBG data capture within the Trace window
component (open the Trace component to display the code program flow rebuild).

Triggers are stored in the debugger as special markpoints. Like breakpoints, markpoints
can be viewed by choosing Show Markpoints in the menu.
Triggers are stored as Trigger A and Trigger B markpoints. These markpoint names are
therefore reserved by the debugger. The markpoint type INSTRUCTION is automatically
selected when the trigger is set from the Source or Assembly window.

Expert Triggers
The Expert Mode has a different set of triggers and trigger designs. Indeed, to completely
separate the Expert mode from the Automatic mode, the debugger provides a second set of
triggers for the Expert mode. Expert Triggers are independent from the regular triggers
described previously.
Context sensitive context menu entries are slightly different, basically replacing the Set
Trigger Address A entry by a Set DBGCA entry and the Set Trigger Address B entry by a
Set DBGCB entry. The renaming is due to a more physical DBG registers approach in
Expert mode and in the Expert Mode Tab.
Figure 23.9 Source Window Context Menu - Expert Trigger Options
As shown in the next picture, Expert triggers are displayed in Source and Assembly
windows with a small additional “e” character and different colors in the Memory
component.
NOTE When the Expert mode is set, preset Instruction Triggers, Memory Access
Triggers or Capture Triggers designs are grayed out. When the automatic mode
is set or a predefined preset trigger is set, the Expert mode trigger designs are
grayed out.

Figure 23.10 Expert Triggers in Source, Assembly, Memory and Data Windows
As shown above, expert triggers are stored in the Markpoints tab of the Controlpoints
Configuration window as DBGCA and DBGCB markpoints. These markpoint names are
therefore reserved by the debugger.
The markpoint type INSTRUCTION is automatically selected when the trigger was set
from the Source or the Assembly window.
As for regular triggers, the markpoint types READACCESS, WRITEACCESS or
READWRITEACCESS are automatically selected when the trigger was set from the
Data or the Memory window.
Just as with regular triggers, editing expert triggers through the Markpoints tab in the
Controlpoints Configuration window is not user friendly. However, the Save and
Restore on load option (also available with breakpoints and watchpoints) can be very
useful to automatically save the application with the current DBG module setup and
trigger positions just as they were used in the application.

DBG Module Mode Setup
First of all, the on-chip DBG module provides some exclusive debugging features. Open
the top list menu to display all modes and complex breakpoints/watchpoints, that is, kind
of triggers available.
Figure 23.16 Trigger Settings Tab Listbox
Automatic Mode (Default)
The DBG Module is used to set up three hardware breakpoints or one watchpoint or to set
up triggers selected by the user from the list or from a context sensitive context menu. This
mode is simply the default selection when no triggers have been set yet.
The trigger condition and trigger addresses can be set from the debugger Source,
Assembly, Memory and Data component using Set Trigger A or Set Trigger B context-
sensitive menu entry, or within this dialog box.
The DBG module is setup to record the executed change of flows. As no triggers are set,
the debugger is stopped on the user request or typical breakpoints/watchpoint. To
summarize, in this mode, the DBG module is used to set regular hardware breakpoints and
watchpoints.

Expert Mode
The User needs to know the on-chip DBG module really well to use this mode. It can be
seen as a “Do It Yourself” way to set the DBG module. The HCS08 core manual is needed
to understand the meaning of the registers and flags.
The triggers comparator addresses can be set from the debugger Source, Assembly,
Memory and Data windows using Set DBGCA or Set DBGCB. The DBG module is set by
the debugger. DBG module enabling and arming depend on the selected flags set within
the DBG register control registers (through the Expert triggers tab property page). The
settings are written to the hardware right before the application is run. The DBG module is
reset when the application stops.
Figure 23.17 Trigger Settings Tab - Expert Mode Information
To set Expert triggers, the Trigger Module Settings window Expert triggers tab must be
used. Select the Expert mode in the list menu to enable the Expert Mode Tab.

Expert Mode Tab
The expert mode tab gives you an access to most of the on-chip DBG module registers.
Trigger types can be directly set from the DBGT - Debugger Trigger Register list menu.
Code program flow rebuild and data recording are also synchronized with the Expert
mode and results are displayed in the Trace Component Window.
Figure 23.18 Trigger Module Settings Window - Expert Triggers Tab
Profiling and Coverage Mode
Choosing this mode, the DBG module is set up to source code execution profiling and
source code execution coverage. Open the Profiler and/or Coverage components to display
results.
Neither triggers nor DBG based controlpoints can be set in this mode, and the debugger
must be stopped on user request (software breakpoints can still be used).
Profiling and Coverage features are based on a periodical debugger program counter real
time fetch from the debugger to the on-chip DBG module. Also this fetch is statistical and
cannot cover all program counters. The longer the program runs the more precise are the
statistics.
See also Limitations section for this mode.
Refer to the debugger engine manual for Coverage and Profiler component features.

The user needs to know the on-chip DBG module to use this mode. It can be seen as a “Do
It Yourself” way to set hardware breakpoints, watchpoints, and triggers. Consult the
Reference Document section and documents to get all information about the HCS08 on-
chip DBG module before attempting to use this mode.
There is no dedicated graphical user interface to access the DBG module register. The
triggers comparator addresses and DBG control registers are handled by the user through
the debugger Memory component or using command line commands. The DBG module is
NOT set by the debugger. DBG module enabling and arming depend on the selected flags
set within the DBG register control registers. The DBG module is NOT reset when the
application stops. By default, the FIFO content is protected from unexpected reads, the
DBG module is automatically disarmed and the FIFO is analyzed when the debugger
stops. This can be optionally disabled by the user.

Trigger Editing
Typically trigger addresses and/or type can be set using context sensitive context menus. It
is also possible to modify trigger addresses and type within the Trigger Module Settings
Window. Pressing Modify Trigger buttons opens a trigger editor dialog box.
Figure 23.30 Browse for Trigger A Dialog Box
In the trigger editor dialog box:
•The Address edit box contains the initial and final trigger address value. This value
can be directly set by typing in the edit box.
•Use the Type list menu to select/change the type of trigger. Use Instruction type for
Instruction Triggers and Read, Write and R/W Access for Memory Access Triggers
and Capture Triggers.
• Pressing Modify Trigger in this sub-dialog box modifies and records the trigger in
the trigger database (Trigger Stored as Markpoints).
NOTE Pressing the OK button does NOT update the trigger database. The Modify
Trigger button in the Trigger Module Settings window must be explicitly
pressed before closing the dialog box to update the trigger database.
• Pressing Delete Trigger in the dialog box removes the trigger in the trigger database
(Trigger Stored as Markpoints). This trigger address is then considered undefined.

Information
A large grayed edit box dynamically provides information about the current triggers and
selected options.
As context sensitive menus only display triggers matching the amount and the kind of
triggers which are currently set, the Trigger Module Settings Window dynamically checks
the validity of current triggers set vs. the trigger mode.
As shown below, if one or more triggers do not match the trigger mode selection, a
warning icon and message appears on the bottom of the dialog box.
Here, the Memory Write Access type of trigger selected by the mouse cursor does not

Microcontrollers Debugger Manual
•Automatically analyze the FIFO content: When the Trace Component Window is
open, after the debugger is halted by the user or a breakpoint, watchpoint or a trigger,
DBG module results are automatically analyzed then displayed in the Trace window.
If the Trace window is closed, the DBG user interface does not perform any result
analysis except trigger flags reported in the status bar. Unchecking this check box
does the same, with the Trace window open.
•Disarm the module automatically when the debugger stops: By default, halting the
debugger target processor with a user break (not a trigger) does not disarm the on-
chip DGB module. If you leave this option selected (the default) the debugger
disarms it to retrieve data from the DBG Fifo. If not selected, the DBG Fifo/buffer
information cannot be retrieved until the module is disarmed.
•Protect DBG FIFO content from unexpected reads: The DBG Fifo data are
retrieved from DBGFH-DBGFL registers (address 0x1814-0x1815 in register block
at reset location). Several reads are performed to retrieve the entire shifting buffer.
However, when the debugger is halted, while refreshing Data and Assembly
windows, it might read also the debugger target processor memory at the same
location, reading the first DBG Fifo data, shifting the buffer, and therefore corrupt
the DBG user interface DBG Fifo data retrieving. This option hides to the debugger
and also user (see blue “-- --” designs in the Memory window at address 0x1814-
0x1815) the DBG Fifo buffer location.
•When starting, automatically step if a trigger is set at PC address (otherwise:
warn): To run again the application, the debugger usually needs to exit the trigger
current match condition and avoid being stuck/halted/locked by the trigger. A single
step is usually required to “escape” from Instruction Triggers. When this option is
disabled, the debugger prompts the following dialog box to validate this choice.

Trace Component Window
The Trace component is a debugger generic component used to display in a Trace window
a debugger internal database. The context sensitive context menu is set up by the
connection (or the GDI DLL) using the component.
Any debugger connections including the DBG user interface are synchronized with the
Trace component.

It is not necessary to open the Trace window/component to make use of the DBG user
interface triggers. However, several triggers are used to collect code program flow
information or access data information. The Trace window can be opened from Specific
Connection Menu Options, from Context Menu Entries in Source, Data, Assembly and
Memory Windows, and from the DBG Support Status Bar Item. The window can by saved
in the debugger layout when pressing the debugger Save icon.
NOTE When the Trace component/window is closed, the debugger might be faster, as
code program flow rebuild is discarded, this last disassembling back the
assembly data from the connection CPU’s memory.
Instructions Display
This display mode is automatically set when Instruction Triggers and Memory Access
Triggers are used. It is also the default display in Automatic Mode (Default).
Displayed columns:
•Frame: A number representing an information item stored in the Trace component
database.
•Address: instruction program counter.
•Instruction: code program flow instruction disassembly.
•FIFO Analyze remark: debugger information: DBG FIFO data means that this data
was recorded by the on-chip DBG module. Traced means an item/instruction
obtained by debugger/user single step or assembly step. Program flow rebuild gap
means that the debugger was unable to completely track the code program flow
between two frames.

Limitations
The following limitations apply in demo/unregistered debugger mode:
• In demo/unregistered debugger mode, code program reconstruction has a limited
number of frames displayed in the Trace window.
• Real time code Profiling and code Coverage are disabled.
• No preset/predefined Instruction Triggers, Memory Access Triggers or Capture
Triggers are provided. Only Expert Triggers can be set.
HCS08 DBG V3 New Features
The following new features are available on version 3 of the HCS08 DBG Module.
MMU and Extended Address Space
By design, the DBG V3 module is compliant with newer devices with the on-chip
Memory Management Unit module, like the MC9S08QE128 devices. The extended
address space memory accesses are supported, and also program flow recording and
rebuild of applications running over PPAGE paging windows (banked memory model).
LOOP1 mode
The on-chip DBG V3 module (available for example on MC9S08QE128 devices)
provides some new features, like an additional comparator that is typically used as a third
hardware breakpoint, that is not involved in the trigger logic except in a new recording
mode call LOOP1. In LOOP1 mode, the DBG module verifies if the last captured change
of flow is already recorded in the DBG fifo database, and if it is the case, the fifo database
is not changed and the capture discarded. This avoids recording short loop changes of flow
that can quickly fill completely the database without providing relevant debug
information. For example, this improves efficiency when executing a DBNZ instruction
by recording instruction branching only once.
Select the LOOP1 module in the Trigger Module Settings dialog by selecting FIFO
LOOP1 mode in a list menu. The genuine mode is called FIFO Normal mode.

Ability to record until Reset and from
Reset
The DBG module now has the ability to record data up until a reset occurs, and can begin
recording immediately after reset.
Recording until reset
The on-chip DBG V3 module can keep in a database the last data recorded right before a
reset occurred, therefore the debugger is now able to trace what happened right before a
reset occurred, at the condition that the module was initially armed to record continuously.
At next debugger stop, the debugger displays in the Trace window the last recorded
instructions and, in red color, the last instructions that could have been executed and
generated a reset.
Also the debugger displays in the status bar the source of the reset decoded from the
System Reset Status (SRS) on-chip register.
CAUTION After interpreting the Trace window recorded information, reset the
debugger and hardware (press the debugger Reset button) to clear the SRS
register. This ensures a correct debugger analysis from the next reset
capture.

RS08 Full Chip Simulation
Full Chip Simulation (FCS) does not involve real input and output. Because of this, it does
not require a target device to be connected to your PC. The RS08FCS connection
simulates code execution on the user’s MCU system, including the function of any
peripherals associated with the device that you select. For more detailed information, refer
to the Full Chip Simulation description for the module that you are using.
Configuration Procedure
To select Full Chip Simulation as the debugger connection:
1. Choose the Full Chip Simulation option from the set connection dialog box. See
Figure 24.1.
2. Click the OK button.

Full Chip Simulation Module Commands
The RS08FCS Menu contains the Full Chip Simulation commands for the modules that
have specialty commands associated with them for a chosen device. For more information
about specific module commands refer to the Full Chip Simulation section describing the
module.
Port Pins Module
Figure 24.4 shows the simulated port inputs dialog box.
Figure 24.4 Simulated Port Inputs Dialog Box
The port pins module menu contains the option to show the input pin levels dialog box
(this corresponds to the INPUTS command). The dialog box graphically displays the
current value of the inputs buffers for all available I/O ports on the device (note that this
may not reflect the value shown in the memory window, depending on the current state of
a given port’s data direction register).
The input buffer can be directly modified from this dialog box.
Modify MTIM TCLK
Figure 24.5 shows the TCLK frequency dialog box.
Figure 24.5 TCLK Frequency Dialog Box
This dialog box allows the user to set the frequency of the TCLK signal for the MTIM
peripheral. In order for this value to have any effect, the TCLK must be selected as the
clock source for the MTIM.

Show Processor Pins
The Processor Pins dialog box is a convenient tool for monitoring the current state of the
processor pins, as well as the peripheral with which a pin may be associated. The
processor is represented, in graphical form, in the middle of the dialog box. Each pin is
labeled with its current function. For example, Pin 2 is the BKGD pin upon reset.
However, with the appropriate write to the SOPT register, the user can observe that Pin 2
changes to PTA3 in the Processor Pins dialog box.
In the dialog box, each processor pin (with the exception of the power pins, Vdd and
GND) has a corresponding arrow. If the arrow points towards the processor, this indicates
that the pin is configured as an input. Conversely, if the arrow points away from the
processor, this indicates that the pin is configured as an output.
Figure 24.6 Processor Pins Window
Below the graphical processor representation are several buttons, each corresponding to a
processor peripheral. Pressing the button of a given peripheral brings up the appropriate
register files (see below), allowing for easy and informative manipulation of all status,
control, and data bits associated with a peripheral.
At the bottom of the dialog box are two additional buttons. The Show Clocks button
brings up the simulated clock frequencies. The Set Inputs button brings up the Inputs
dialog box, which allows the user to set the simulated input buffers to any valid value.

ColdFire V1 Full Chip
Simulation Connection
The Full Chip Simulation (FCS) connection runs a complete simulation of all processor
peripherals and I/O on the user's Personal Computer. No development board is required.
Each derivative has a unique simulation engine to accurately simulate the memory ranges,
I/O, and peripherals for a given derivative (for more information on selecting a specific
derivative, see the FCS and Silicon On-Chip Peripheral Simulation sections).
This section presents the first steps to debugging using the CodeWarrior debugger and the
ColdFire V1 Full Chip Simulation connection.

Figure 28.5 Full Chip Simulation Connection Command Files Window
Setcpu Command File
The Setcpu command file is specific to FCS and the Debugger executes the command file
after a CPU has been set or modified. This occurs when you use the setcpu command or
when you load an application in the FCS when the corresponding CPU is not set.
You can specify the Setcpu command file full name and status (enable/disable) either with
the CMDFILE SETCPU Command Line command or by using the Setcpu property tab
of the connection Command Files dialog.
The default Setcpu command file is SETCPU.CMD. By default the SETCPU.CMD file
located in the current project directory is enabled as the current Setcpu command file.
Memory Configuration
The memory configuration interface is an FCS advanced configuration feature. The FCS
divides the emulated memory into blocks. A memory manager handles the list of memory
blocks. The memory configuration facility offers you some degree of automation, but does
not restrict the flexibility of manual adjustment. The memory configuration facility lets
you specify types and properties of memory blocks, such as RAM and ROM.
The memory configuration facility uses a binary file format to read and set the FCS
configuration. The extension for binary files is .mem; the default memory file is
default.mem. (The subsection TestTerm Component includes Listing 28.2, the EBNF-
syntax definition of the file format.)

Memory Configuration Modes
Use the Memory Configuration dialog box to select the memory configuration mode:
auto configuration on access, auto configuration on load, or manual configuration
(user defined). Depending on your settings, the FCS component initializes the FCS
memory as Table 28.2 explains.
Memory Configuration Settings
Depending on the configuration mode, the Memory Configuration dialog box lets you
redefine memory settings within certain limits. You must always set I/O devices manually.
Standard Configuration: Auto on Access: The Memory Configuration dialog box contains
a single RAM entry with unspecified (*) starting and ending addresses. You cannot
modify these addresses. You can adjust wait states, and other such settings, only for the

Auto Configuration on Load: Initially, the dialog box lists a single RAM and a single
ROM block, with unspecified (*) starting and ending addresses. You can adjust wait states
and other settings separately for RAM and ROM blocks.
For the ELF/DWARF Object file format, the Memory Configuration dialog box lists
separate RAM and ROM blocks for each data and code segment in the absolute file, once
an application has been loaded. The segment addresses and lengths determine the starting
and ending addresses of each block; you cannot modify these addresses. Initial attributes
of each code and data block come from the corresponding initial RAM and ROM blocks;
you can modify these attributes independently.

Clock Frequency Setup
The Full Chip Simulation provides a true time information. It is possible to provide an
oscillator clock frequency to the debugger. The debugger CPU awareness and IO modules
provide the "clock factor" to apply to this input frequency to derive the CPU cycle
frequency.
Figure 28.8 Clock Frequency Setup Dialog Box
Derivative-specific IO simulations which require bus speed change information (multiply
or divide) from the PLL modules update the clock factor while the application simulation
is running.
This does not affect the accumulated elapsed time, and applies a new cycle time to the
next simulated instructions in real time.
Open the Clock Frequency Setup dialog (Simulator > Clock Frequency) to set, enter, or
edit either the oscillator frequency or the CPU frequency. However, the saved project

frequency is always the oscillator frequency. Two radio buttons allow you to choose
between cycles or true-time display in debugger status bar.
Clearing Reset cycles/time makes the debugger accumulate cycles/time other than CPU
reset. The true-time unit is the microsecond. The TRUETIME debugger command line
command gives the time as a number in microseconds. The OSCFREQUENCY variable
displays or sets the oscillator frequency.
Bus Trace
The FCS can record all executed instructions and memory accesses in the Trace
component, up to one million frames. Enable recording in the Trace menu or context-
sensitive menu after opening the Trace component.
NOTE Refer to the ColdFire On-Chip DBG Module manual for the Trace Component
Window common functionality and common menu entries.
Figure 28.9 Trace Window Context Menu
By default, FCS records instructions only (faster). Check Record memory accesses and
choose Textual mode in the Trace menu or context-sensitive menu to record memory
accesses as well.
![](asset-24c.png)

You can retrieve the following types of information from the Trace window:
• Instructions and instruction addresses,
• Data address, data value and read/write access type,
• True time, cycles and total simulation cycles for each instruction,
• Function name and module name for each instruction,
• Variable name and module name for each global variable data access.

Full Chip Simulation Warnings
By default, the FCS generates warning messages when the application accesses on-chip
registers that are not implemented for the selected derivative. These warnings appear in
the Command window.
For example, the following messages can be indefinitely repeated in the Command
window:
...
...
...

STOPPING
HALTED
Warning message IDs usually belong to a group of registers from the same simulated
block (the messages above are from the Flash CONTROL registers block). Therefore, any
access to an unimplemented Flash CONTROL register generates the same kind of
message.
The debugger provides a set of commands to hide specific ID messages, to stop the FCS
automatically, or to display a warning message box. You can executes these commands
from a POSTLOAD command file. These commands are volatile and not saved in current
project.

Full Chip Simulation not only simulates the core instruction set but also the on-chip I/O
devices. For each implemented derivative or derivative family there is an FCS
implementation note in the Help\pdf folder of the CodeWarrior installation named
FCS_Notes_<derivative name>.pdf. These documents contain details on the
implementation of each peripheral module within the derivative.
Generating a new project with the New Project Wizard and the connection Full Chip
Simulation sets everything up to run the project with FCS support.
Use Simulator > Set Derivative to change the derivative to simulate. In addition to the
derivatives there are the special entries ColdFire V1 CORE and ColdFire V1 SAMPLE.
The CORE entries allow you to simulate the chip without FCS support (plain instructions
only) and the SAMPLE entries allow you to simulate a chip with a minimal set of
commonly-available on-chip peripherals.

The ADC_DAC window shown in Figure 28.20 consists of an Analog to Digital (ADC)
and a Digital to Analog (DAC) converter.
Figure 28.20 ADC/DAC Window
Description
The ADC/DAC component consists of four units as shown in Figure 28.21:
• A signal generator
• An analog to digital converter (ADC)
• A digital to analog converter (DAC)
• A visualization unit

Microcontrollers Debugger Manual
Figure 28.21 Internal Converter Module Organization and Coupler Connections
The fourth unit shows the value of the initial analog signal and value of the DAC output
analog signal.
This component communicates with the mainframe through three parallel ports of eight
bits:
• A port with 1 significant bit to indicate the conversion state.
• An input port to recover the ADC values
• An output port to send values to the DAC in order to visualize them
Signal Generator
The signal generator only generates a sinus signal. The generator output connects to the
ADC visualization screen.
Visualization Screen
The visualization screen is a 200-point horizontal resolution screen. The sinus signal
period deploys in red by default, shown in the upper part of the screen in Figure 28.20, and
the signal generated by the DAC appears in blue in the lower part.
ADC
The ADC is an 8-bit resolution converter generating unsigned values. Figure 28.21 shows
that its entry is directly connected to the signal generator. The conversion order is given by
a timer that is not connected to the data bus, therefore it cannot be set by software.
At the end of a conversion, the ADC sets the state bit. This bit automatically resets after
read.

IT_Keyboard Component
The 20-key IT_Keyboard shown in Figure 28.26 generates an interruption when a key is
pressed.
Figure 28.26 IT_Keyboard Window
These 20 keys are positioned at the intersection of the five lines, X0 to X4, and the four
columns, Y0 to Y3. The resistor R connected to the positive supply gives a logical level 1
when there is no connection (key not pressed). The activation of a line (or column) gives a
logical level 0, and a key pressed on this line (or column) places the column (or the line)
corresponding on the low level. For example, if you activate line X2, column Y3
decreases from logical level 1 to logical level 0 when the « B » key is pressed.
An interruption is raised when an active key (line or column activated) is pressed.

Scanning is one method to read such keyboards. Typically, we can proceed as follows (the
line being in output and the column in input):
• Put a 0 at line X4 (X3, X2, X1, X0 being at 1).
• Read the column successively, from Y3 to Y0.
• Put a 0 at line X3 (X4, X2, X1, X0 being at 1).
• Read the column again from Y3 to Y0.
• Continue till the last column of the last line, and restart at the beginning
All keyboard keys are scanned until we find one that is activated. During the scanning
process, it is easy to update a counter representing the number of the key pressed. Raising
an interruption when a key is pressed allows you to scan only when a key is activated
rather than constantly.

LCD Component
The LCD Display component message box shown in Figure 28.30 is the LCD utility,
which can display one or two lines of 16 characters and show or hide the position cursor.
Figure 28.30 LCD Display Message Box
The display module consists of two 8-bit-wide parallel couplers: a data port and a control
port, as shown in Figure 28.31. These ports communicate with the mainframe.
Figure 28.31 The LCD Display Module Ports
The bits d7-d0 represent an ASCII code to display characters or an instruction code. The
RS bit defines the status of bits d7-d0.
LCD Operation
The LCD Display device can display one or two lines of 16 characters and show or hide
the position cursor.
To manage the display, this device contains a controller: the DDRAM (Display Data
RAM). The DDRAM stores the ASCII codes of characters written during a write
operation. Only two lines of 16 characters each can be displayed but up to 64 characters
can be stored.
This RAM can be seen as organized in two lines: the first one starts at address 00h and
ends at 1Fh, and the second one starts at 40h and ends at 5Fh. Figure 28.32 illustrates this
arrangement.
![](asset-261.png)
ColdFire V1 Full Chip Simulation Connection
FCS Visualization Utilities
609
Microcontrollers Debugger Manual
Figure 28.32 The DDRAM Controller
The Address Counter (AC) is an internal register of the display controller which points at
the current address. In the default configuration AC is initialized at 00h and increases
when an ASCII character is stored at the address to which AC points. When AC is equal to
1Fh, the next increased value is not 20h, but 40h.
For example, if we send a 48-character string after initialization, the AC stores the bytes at
addresses 00h to 1Fh and 40h to 4Fh.
NOTE Only characters having their ASCII codes in the visible interval of the 16
characters (positions 1 to 16) of RAM appear.
Sending Information to the Display
Two steps are necessary to display a character:
1. Set the E and RS bits at 1 and the R/W bit at 0 (control word 00000100b)
2. Write the character ASCII code on the data port. Set bit E to 0 (this validates bits d7-

For an instruction, only step 2 is different: the Byte to write on the data port is the
instruction code you want the display controller to execute.

Cursor or Display Shift
• Doesn't change the DDRAM content.
• Leaves AC in case of a screen shift.
• Moves and/or shifts the cursor to the right or left. The cursor goes to the second line
if it exceeds the 32nd position of the first line. It also goes to the first line when it
exceeds the 32nd position of the second line.
• During a screen shift the two lines only move horizontally, the first line never passes
to the second one.
Figure 28.34 describes how to choose the moving direction.
Figure 28.34 Left Right Choice
Set DDRAM Address
• Puts the address indicated by a6a5a4a3a2a1a0 into AC.
• When the number of lines is 2, the address goes from 00h to 1Fh for the first line, and
from 40h to 5Fh for the second line.
•The a6 bit indicates the line: a6=0 indicates the first line and a6=1 indicates the
second line.
Function Set
• If DL = 1, the data exchange is 8 bits wide.
• If N = 0, the display takes place on one line. If N = 1, the display takes place on two
lines.

Programmable IO_Ports Component
The Programmable IO_Ports window shown in Figure 28.47 consists of five IO_Ports
with eight configurable bits in input or output. In the default configuration all couplers are
in input. The graphical interface suggests the state of each one.
Figure 28.47 Programmable IO_Ports Window
The debugger uses circuits called «input / output couplers » to complete the data exchange
between the processor and peripherals. The peripherals are connected to the data bus in
parallel. The appropriate output circuit catches information on the data bus and saves it (in
a latch) until the next data reception.
The processor perceives the input/output couplers as memory cases with a wired fixed
address. The capability exists to do input/output actions at a known address. In C, access is
accomplished using forced pointers to these addresses.
A read operation when the coupler is in input mode activates this input during all the read
steps. A write operation when the coupler is in output mode activates the output latch
during all write steps.
The programmable IO_Ports allows you to define the coupler in input and output. You
can modify this configuration during program execution. The first step in the test program
is to configure the appropriate couplers.

7-Segments Display Component
The 7-Segments Display window shown in Figure 28.51 consists of eight 7-segment
display systems.

Operation of the 7-segments display component is based on the display scanning
principle. Only one display can be activated at a time, for the purpose of limiting
consumption of the set.
Common segment connection is the strength of the component. The other connections
serve as code input, so the same code applies to all seven, as shown in Figure 28.52.
Scanning consists of selecting a display and activating its segments with adequate code to
the input terminals and then attending to the next display.

TestTerm Component
The TestTerm window shown in Figure 28.59 is a user-friendly terminal input/output. It
provides a simple SCI (Serial Communication Interface) interface, which is independent
of Full Chip Simulation.
Figure 28.59 TestTerm Window
The TestTerm component emulates a serial communication interface based at the address
200 (hexadecimal), thus providing five simulated memory mapped registers described in
Table 28.12.
![](asset-273.png)
ColdFire V1 Full Chip Simulation Connection
FCS Visualization Utilities
627
Microcontrollers Debugger Manual
Table 28.13 describes the bits used in the Serial Communication Status Register.
Reading and writing in the BAUD, SCCR1, SCCR2 or SCSR registers has no effect in the
TestTerm component, but are required to make the component compatible with specific
SCI interfaces.
Simulated I/Os of the TestTerm component do not need initialization. In the terminal
interface file termio.c, BAUD and SCSR registers are initialized to be compatible with
real SCI interfaces.
The SCDR register is valid for reading or writing data. Reading a value from the SCDR
register clears the RDRF flag in the SCSR register. Entering a character on the keyboard
while TestTerm is active sets the RDRF flag in the SCSR register and puts the ASCII code
of the typed key into the SCDR register.
Conceptually, writing a new value in the SCDR register by the target application clears the
TDRE flag in SCSR. Transmission completion sets the TDRE flag again. As TestTerm is
only an I/O emulation, no delay is simulated and writing into SCDR sets the TDRE flag in
the SCSR register.
Output Redirection
Output can be redirected to a TestTerm window, a file, or to both at the same time. File
output is monitored by the target system and cannot be specified interactively.

Use Escape sequences to handle redirection of the output data stream. Table 28.14
illustrates the different possible redirections and associated escape sequences where
filename is a sequence of characters terminated by a control character (e.g., CR) and is
a valid filename.
ESC is the ESC character (ASCII code 27 decimal).
Use these commands anywhere in the output stream.
How to Redirect
By default, an output redirection is set to the TestTerm component window.
The debugger uses the Term_Direct function declared in terminal.h to redirect an
output. Listing 28.2 gives the source code in terminal.c.
Listing 28.2 Term_Direct Source Code
void Term_Direct(int what, char *fileName)
{
if (what < 1 && what > FROM_FILE) return;

if (what != TO_WINDOW && what != FROM_KEYS) {
PutString(fileName); Write(CR);
}
}
In this case, what is one of the following items:

Terminal Component
Use the Terminal window shown in Figure 28.62 to simulate input and output. It can
receive characters from several input devices and send them to other devices.
Figure 28.62 Terminal Window
You can use a virtual SCI (Serial Communication Interface) port provided by the
framework for communication with the target, but it is also possible to use the keyboard,
the display, some files or even the serial port of your computer as I/O devices.
To control and configure a terminal component use the Terminal menu of the terminal
shown in Figure 28.63.

To open the context menu, right click in the terminal window.
![](asset-278.png)
ColdFire V1 Full Chip Simulation Connection
FCS Visualization Utilities

Microcontrollers Debugger Manual
Configure Terminal Connections
The terminal window is very flexible and can redirect characters received from any
available input device to any available output device. You can specify these connections
by choosing Configure Connections in the context menu of the terminal component. This
opens the dialog box shown in Figure 28.64.
Figure 28.64 Configure Terminal Connections Dialog Box
You can choose one of the default configurations in the Default Configuration combo
box. The Connections section lists all active connections in a list box. There you can
customize which input devices to redirect to which output devices by adding and
removing connections.
To add a connection, specify the source and target devices using the From and To combo
boxes and then press the Add button. The new connection appears in the active connection
list below.
To remove connections, select them in the list of active connections and press the Remove
button.
In the Serial Port section you can specify which serial port to use and its properties. This
is only possible if at least one connection from or to the serial port exists.
![](asset-279.png)
ColdFire V1 Full Chip Simulation Connection
FCS Visualization Utilities
633
Microcontrollers Debugger Manual
If you have chosen a connection from or to the virtual SCI port, you can also specify, in
the Virtual SCI section, which ports to use as virtual SCI ports. This enables you to make
a connection to any port in the FCS framework.
Input and Output File
You can use a file as an input stream for the terminal component or redirect the output to a
file.
To use a file as an input stream, make sure that at least one connection exists from the
input file to any output device. Then you can open an input file by choosing Input File
from the context menu. As soon as you press the OK button in the File Open dialog, input
from the file starts. The file closes as soon as the end of file is reached or when you choose
Close Input File from the context menu.
When the input file reaches its end a CTRL-Z character (ASCII code 26 decimal) is sent to
all output devices receiving characters from the input file to notify them that the file
transfer is complete.
Redirecting input devices to an output file is a similar process. Choose your connections
from input devices to the output file. Then open or create your output file by choosing
Output File from the context menu. If the file does not exist the debugger creates it.
Otherwise you can choose to overwrite or append the existing file. To stop writing to the
output file choose Close Output File from the context menu.
File Control Commands
You can open and close input and output files through special Escape sequences in the
data stream from the serial port or virtual SCI. Table 28.15 illustrates the different possible
commands and associated Escape sequences where filename is a sequence of
characters terminated by a control character (e.g. CR) and is a valid filename.
Table 28.15 Terminal File Control Commands
Escape Sequence Function
ESC “h” “1” Close output file.
ESC “h” “2” filename Open output file.
ESC “h” “3” filename Open output file and suppress output to terminal display.
ESC “h” “4” Close input file
ESC “h” “5” filename Open input file.
![](asset-27a.png)
ColdFire V1 Full Chip Simulation Connection
FCS Visualization Utilities
634
Microcontrollers Debugger Manual
ESC is the ESC Character (ASCII code 27 decimal).
You can give these commands in the data stream sent from the serial port or virtual SCI
port, but not from the input file or the keyboard. They have an effect only if there are any
connections reading from the input file or writing to the output file.
Use the TERM_Direct function declared in terminal.h to send such commands from
a target via SCI to the terminal. Listing 28.5 gives the source code in terminal.c.
Listing 28.5 TERM_Direct Source Code
void TERM_Direct(TERM_DirectKind what, const char* fileName) {
/* sets direction of the terminal */
if (what < TERM_TO_WINDOW || what > TERM_APPEND_FILE) return;
TERM_Write(ESC); TERM_Write('h');
TERM_Write((char)(what + '0'));
if (what != TERM_TO_WINDOW && what != TERM_FROM_KEYS) {
TERM_WriteString(fileName); TERM_Write(CR);
}
}
In the example, the parameter what is one of the following constants:
•TERM_TO_WINDOW: send output to terminal window
•TERM_TO_BOTH: send output to file and window
•TERM_TO_FILE: send output to file fileName
•TERM_FROM_KEYS: read from keyboard (close input file)
•TERM_FROM_FILE: read input from file fileName
•TERM_APPEND_BOTH: append output to file and window
•TERM_APPEND_FILE: append output to file fileName
See also terminal.h for further details.
ESC “h” “6” filename Append to existing output file.
ESC “h” “7” filename Append to existing output file and suppress output to terminal
display.

Using the Virtual SCI
In its default Virtual SCI configuration the terminal component accesses the target
through the Object Pool interface.
To make the terminal component work in this default configuration, the target must
provide an object with the name Sci0. If no Sci0 object is available, no input or output
happens. It is possible to check, through the Inspector component, whether the
environment currently provides an Sci0 object.
NOTE Only some specific FCS components currently have an Sci0 object. For all
other FCS components the default virtual SCI port does not work, unless you
load a user-defined Sci0 object with the specified register name.
Write access to the target application is done with the Object Pool function OP_SetValue
at the address Sci0.SerialInput.
A subscription to an Object Pool register with the name Sci0.SerialOutput handles input
from the target application. When this register changes (sends a notification), a new value
is received.
For implementations of this register with help of the IOBase class, use the
IOB_NotifyAnyChanges flag. Otherwise only the first of two identical characters are
received.
It is also possible to configure the terminal to use another object in the Object Pool instead
of Sci0 with which to communicate. Refer to Configure Terminal Connections for
information about where you can do this.
Cache Size
The item Cache Size in the context menu allows you to set the number of lines in the

Wagon Setup
When you select Setup from the Wagon Menu, the Ports Address Selection dialog box
appears. This is the Wagon component Setup window.
Figure 28.68 Ports Address Selection Dialog Box
In the Motor Port section, you can insert an address (in hexadecimal) to select the Wagon
direction. In the Sensor Port field you can insert an address (in hexadecimal) to select the
Wagon position. Predefined ports are fixed when the component operates with the
Programmable IO_Ports Component.
Control Bits Configuration
The 2 bytes sent to the wagon component must be composed as shown in Figure 28.69.
Figure 28.69 Wagon Control Bits Description
To move the wagon to the right, set bit r. To move the wagon to the left, set bit l. The
sensor port sets the bl bit when the wagon is at the left border, sets bit br when the wagon
is at the right border, sets bit st when you click the START button with the left mouse
button, and sets stp when you click the STOP button.

True Time I/O Stimulation
The FCS I/O Stimulation component is a facility to trigger I/O events. With the
Stimulation component loaded, you can simulate interrupts and register modifications
invoked by the hardware. This tutorial introduces and explains examples of stimulation
files. This section contains the following subsections:
•Stimulation Program Examples
•Stimulation Input File Syntax
Stimulation Program Examples
The following examples illustrate common stimulation programs.
Running an Example Program Without
Stimulation
1. Run the debugger with the FCS connection.

5. Choose Simulator > Load io_demo.abs.
6. Choose Run > Start/Continue or click the green arrow icon.
7. If the program halts in startup, click the Start/Continue command again.
8. Choose Run > Halt to stop execution after a few seconds.
The Template component is a view linked to a specific memory location in TargetObject.
In the source code of the test program, you can find a variable associated with it:
#define PORT_DATA (*((volatile unsigned char *)0x0210))/* Value
with range 0..255 */
The Template component polls this value and displays it in a speedometer-like outlook.
The procedure IO_Show in io_demo.c, shown in Listing 28.6, increments or
decrements this value, depending on the raise direction. The raise direction depends on a
global variable dir that is turned back when the top or bottom value is reached.

Microcontrollers Debugger Manual
The Stimulation component executing io_var.txt accesses TargetObject at address
0x210 associated with PORT_DATA in the source. You can observe this by watching the
Template component. The arrow is not raising steadily, but jumps around. The
Stimulation component now handles the value of PORT_DATA.
Using an editor, open the file named io_var.txt in the FCS demo directory. This file
looks like Listing 28.7.
Listing 28.7 io_var.txt
/* Define an identifier a, which is located at address 0x210*/
/* This identifier is 1 Byte wide.*/
def a = TargetObject.#210.B;
/* After 200 000 cycles have expired, repeat 50 time */
/* the code sequence specified between the keywords */
/* PERIODICAl and END. */
PERIODICAL 200000, 50:
50000 a = 128; /* After 50 000 cycles, write 128 at address 0x210. */
150000 a = 4; /* After 150 000 cycles, write 4 at address 0x210. */
END
10000000 a = 0; /* After 10 000 000 cycles, write 0 at address 0x210. */
First, the simulated object is defined. This object is located at address 0x210 and is 1 byte
wide. Once 200,000 cycles have been executed, the memory location 0x210 is accessed
periodically 50 times. First the memory location is set to 128, then 100,000 cycles later, it
is set to 4.
Example Program with Stimulated Interrupt
1. Choose Simulator > Reset.
2. Activate Stimulation Window by clicking on it.
3. Choose Stimulation > Open File io_int.txt.
4. Select the Source component window.
5. Choose Source > Open Module io_demo.c.
6. Scroll into the procedure Interrupt_Routine.
7. Set a breakpoint in the Interrupt_Routine as shown below.
Figure 28.74 shows the Source component window.

Microcontrollers Debugger Manual
Figure 28.74 Source Component Window
8. Activate the Stimulation Window by clicking on it.
9. Choose Stimulation > Execute.
10. Choose Run > Start/Continue.
After about 300,000 cycles the FCS stops on the breakpoint in the interrupt routine and
highlights the corresponding source line. The interrupt is called. Start the FCS. It stops
approximately each 100,000 cycles on the same breakpoint. Restart and repeat these
actions until 1,200,000 cycles. Start again. The FCS runs until 10,000,000 cycles and stops
on the breakpoint. Start the FCS. It continues to run. The stimulation is finished.
The interrupts have been invoked by the Stimulation component source io_int.txt.
Listing 28.8 gives the Stimulation file listing.
Listing 28.8 io_int.txt
def a = TargetObject.#210.B;
PERIODICAL 200000, 10:
100000 RAISE 7, 3, "test_interrupt";
END
10000000 RAISE 7, 3, "test_interrupt";
In the first line, the stimulated object is defined. The interrupt is raised periodically ten
times. The RAISE command takes the number of the interrupt in the interrupt vector map
as the first argument. This number 7 in our example is arbitrarily chosen. To export this
example to a different target processor, look at the interrupt vector map in the technical
data manual of the matching MCU. Using an editor, open the io_demo.prm file in the
same demo directory. You can see at the end of this file how to set the interrupt vector
(adapt it to your needs).
![](asset-283.png)
ColdFire V1 Full Chip Simulation Connection
True Time I/O Stimulation
643
Microcontrollers Debugger Manual
VECTOR 7 Interrupt_Function /* set vector on Interrupt 7 */
If the prm file does not specify the interrupt vector address, the FCS stops when
interruption is generated. The exception mnemonic (matching the interrupt vector number)
appears in the FCS status bar.
The second argument specifies the interrupt priority and the third argument is a free
chosen name of the interrupt.
The file io_int.txt is used to generate 11 interrupts. Ten periodical interrupts are
generated every 100,000 CPU cycles from 200,000 + 100,000 = 300,000 to 1,200,000
CPU cycles. A final interrupt is generated when the number of CPU cycles reaches
10,000,000.
Example of a Larger Stimulation File
Listing 28.9 contains this example and is commented below. This example file may not
work as expected if the variables defined here do not refer to a port in TargetObject. In our
example, we only defined the objects TargetObject.#210 and #212 over the
Io_led component. Definitions of b, c and pbits are here for illustration only. Remove
these definition lines and the lines that refer to them, if the example presented here is not
executable.
Listing 28.9 Example File io_ex.txt.
def a = TargetObject.#210.B;
def x = TargetObject.#212;
def b = TargetObject.#216.W;
def c = TargetObject.#220.L;
def pbits = Leds.Port_Register.B[7:3];
#10000 pbits = 3;
20000 a = 0;

![](asset-284.png)
ColdFire V1 Full Chip Simulation Connection
True Time I/O Stimulation

Microcontrollers Debugger Manual
Detailed Explanation
def a = TargetObject.#210.B;
This line of code defines a as byte mapped at address 0x210 in TargetObject.
def x = TargetObject.#212;
This line of code defines x as byte mapped at address 0x212 in TargetObject. Size can be
omitted. .B for byte is default.
def b = TargetObject.#216.W;
This line of code defines b as word (.W) mapped at address 0x216 in TargetObject.
def c = TargetObject.#220.L;
This line of code defines c as long (.L) mapped at address 0x220 in TargetObject.
def pbits = Leds.Port_Register.B[7:3];
This line of code defines pbits as bits 5, 6 and 7 in the byte (.B) register named
Port_Register in LEDs. (You can specify names of target objects when using FCS. In our
example, it is the name of the port register defined by the IO-LED component).
#10000 pbits = 3;
This line of code sets the three bits of LEDs. Port_Register accessed with pbits to binary
011. Other bits are unaffected. The new value of Port_Register is 0x75 if the initial value
was 0x55. Values outside the valid BitRange of pbits are truncated (in this example
only values from 0 to 7 are allowed for pbits). The # means that the time of execution of
the instruction is 10000 cycles after the start of the simulation.
20000 a = 0;
This line of code sets a to 0. Without # or + in front of the time marker, the time refers to
the absolute time after starting execution of the Stimulation file.
NOTE In a periodical loop, the time marker without operator is interpreted as +.
+20000 b = pbits + 1;
![](asset-285.png)
ColdFire V1 Full Chip Simulation Connection
True Time I/O Stimulation
645
Microcontrollers Debugger Manual
This line of code reads pbits (three bits in Leds. Port_Register), increments this
value and writes it to b. The + in front of the time marker refers to the time relative to the
last encountered time value in the Stimulation file.
PERIODICAL 100000, 10:
This line of code executes the following block 10 times:
10000 a = 128;
30000 RAISE 7, 3, "test_interrupt";
This starts execution 100,000 cycles after the start of the simulation.
10000 a = 128;
This line of code assigns 128 to a, 10000 cycles after each start of the periodic event.
30000 RAISE 7, 3, "test_interrupt";
This line of code raises an interrupt with priority 3 with vector number 7, 40000 cycles
after each start of the periodic event. The time specification in the PERIODICAL loop is
always relative, so 30000 means +30000. The raised interrupt has the name
test_interrupt. This name is not important for the interrupt functionality.
END
This line of code is the end of the periodic block. The block loops again after finishing, so
the loop restarts after 10000 + 30000 = 40000 cycles.
1000000 RAISE 7, 3, "test_interrupt";
This line of code raises the interrupt for the last time. This instruction marks the
terminating point of the Stimulation, if there are no pending periodical events left.
Stimulation Input File Syntax
The following listing shows the EBNF input file syntax.
Listing 28.10 EBNF
StimulationFile = { IdDeclaration | TimedEvent | PeriodicEvent }.
IdDeclaration = “def” ObjectId “=” ObjectField “;”.
ObjectField = ObjectSpec [ “[” BitRange “]” ].
BitRange = StartBit “:” NoOfBits.
![](asset-286.png)
ColdFire V1 Full Chip Simulation Connection
True Time I/O Stimulation
646
Microcontrollers Debugger Manual
TimedEvent = [ “+” | “#” ] Time AssignmentList.
AssignmentList = { Assignment | Exception}.
PeriodicEvent = “PERIODICAL” Start “,” NbTimes “:” { PerTimedEvent }
“END” .
PerTimedEvent = [“+”] Time AssignmentList .
Exception = “RAISE” Vector “,” Priority [“,” ArbPrio] [“,” Name] “;” .
Assignment = ( ObjectId | ObjectField ) “=” Expression “;”.
Name = ““” {character} “”” .
In this listing, the following parameters apply:
•Expression = a standard ANSI-C expression. The expression accepts object
identifiers previously defined (ObjectSpec and ObjectField).
•Time = a number which represents a number of cycle.
•ObjectSpec = the name of an object as defined in Requirement specification for
Object Pool.
•Vector = the exception vector number.
•Priority = the exception priority number.
•ArbPrio = the arbitration priority of the exception.
•Start = the number of cycle when the periodical event must be called for the first
time after the initial time.
•NbTimes = the number of times the periodical event must be called (0 = infinity).
Remarks
• Omitting bitRange affects all bits of the object register. Specifying bitRange applies
the mask defined by this bitRange to the value calculated with the Expression. This
value only affects the bits of the object register defined in the bitRange.
• Bits are numbered from right to left (in a byte, bit 7 is the left-most bit). In bitRange,
noOfBits is always less than or equal to StartBit +1.
• The requirement specification defines ObjectSpec for Object Pool as shown below:
ObjectSpec ::= ObjectName [“.” FieldName].
ObjectName ::= Ident [“:” Index].
FieldName ::= IdentNum ( [“..” IdentNum] | [“.” Size] ).
IdentNum ::= Ident | “#“ HexNumber.
Size ::= “B” | “W” | “L”.

Microcontrollers Debugger Manual
• The identifiers declared in IdDeclaration are stored in a table of identifiers and can
be also used in Expression.
• If “#” is specified, the time is absolute: it is the number of cycles since the Full Chip
Simulation was started.
• If “+” is specified, the time is relative to the previous time specification.
• If nothing is specified, time is the number of cycles since execution of the
Stimulation file.
• If size is omitted, the default size is byte (B).
• The periodical event is sent for the first time at initial time + start + time specified in
periodical timed event.
•In the PerTimedEvent declaration, the “+” is optional. If specified or not, the
following time is interpreted exactly the same way.
• The periodical events are not displayed in the stimulation screen.
Electrical Signal Generators and Signals
Application to Device Pins
Signal IO Component
This Signal IO is the first implementation of a Signal Generator reading, in real
debugger time, a file describing (electrical) levels. Levels are applied and available at a
virtual IO pin called SignalPin as float value.
Levels are programmed one after the other during the debugger internal Event queue of
the FCS.
If levels duration value is less than cycle time or smaller than cycles, undersampling is
performed in the signal file.
You can run up to 16 Signal Generators at the same time.

ColdFire V1 Full Chip Simulation Connection
Electrical Signal Generators and Signals Application to Device Pins
650
Microcontrollers Debugger Manual
INF means infinite loop. If a block is INF, scanning stays in this block till the IO is
closed or CLOSESIGNALFILE command is executed. If a number is specified,
loops that number of times.
• TIMEUNIT
–CYCLES means that the second data field are cycles.
–SECONDS means that the second data field are seconds.
–-NONE means that the second data field does not exist and the data time unit is
forced to 1 second. Then data time unit can then be adjust by the TIMEFACTOR
parameter.
• TIMEFACTOR
At event programming, multiplies the number of cycles or time duration by this
factor.
• GAIN
At Pin level setup, multiply the level by this gain.
• DCOFFSET
At Pin level setup, level offset applied after gain is applied.
•OPTION
–NORMAL: do nothing.
–ONLYPOSITIVE: at Pin level setup, after gain and offset, cleared to 0 if signal
level < 0.
–ONLYNEGATIVE: at Pin level setup, after gain and offset, cleared to 0 if signal
level > 0.
–ABSOLUTE: at Pin level setup, after gain and offset, set |signal level|.
Signal IO Usage
The Signal IO can handle 16 signals at the same time. Each signal block is independent in
parameters and options from other blocks. You can open the Signal component within
Open I/O Component Dialog Box or with the openio signal command. Release it
within the same dialog or with the close signal command.
Signal Commands
The following signal commands are available in FCS:
![](asset-28b.png)
ColdFire V1 Full Chip Simulation Connection

Microcontrollers Debugger Manual
SETSIGNALFILE Command
SETSIGNALFILE specifies the signal file to use.
The SETSIGNALFILE X command creates a virtual SignalGeneratorX module
having a SignalPin.
The file name can include the path of the file. If no path is given, the Signal
component will first search in the current project folder, then in the prog\FCSsignals
folder of the debugger installation path.
Syntax
SETSIGNALFILE <value (0-15)> <"file name">
Example
To create three generators:
setsignalfile 0 "sinus_11bit_0_5v_1Hz.txt"
setsignalfile 1 "saw_11bit_0_5v_1Hz.txt"
setsignalfile 2 "square_1_5v_1Hz.txt"
Then, perform virtual pin connections with the Pinconn IO CONNECT command:
connect "SignalGenerator0.SignalPin","Atd0.PAD0"
connect "SignalGenerator1.SignalPin","Atd0.PAD1"
connect "SignalGenerator2.SignalPin","Atd0.PAD2"
TIP Commands to create a signal generators can be placed in a command file like a
Postload command file.
CLOSESIGNALFILE Command
CLOSESIGNALFILE closes the current signal file and generator.
Syntax
CLOSESIGNALFILE <value (0-15)>

ColdFire On-Chip DBG
Module
The ColdFire® derivatives featuring an on-chip debugger (DBG) module require a
debugger graphical user interface to setup this module and take full advantage of this
enhanced debugging feature. This manual describes the DBG module user interface.
Within several ColdFire debugger connections, a complete graphical user interface is
provided, through a trigger setup dialog box combined with context-sensitive context
menus (mouse right-click) in Source, Assembly, Data and Memory component windows
to set the on-chip DBG module and triggers.
This DBG module support is automatically enabled or disabled, according to user selected
derivative (if the device is user configurable) or automatically through device Part ID.
TIP Refer to HCS08 On-Chip DBG Module for general information. This section
gives details of specific setup for the ColdFire debug module.
DBG Features
The debugger covers all features available within the on-chip DBG module:
• Regular hardware breakpoints and watchpoints,
• Predefined preset Instruction Triggers or Memory Access Triggers, a wide set of
complex hardware breakpoints (triggers on program code instructions) and
watchpoints (triggers on device memory access) and data bus recording,
• Expert Triggers, as powerful as predefined preset triggers, “Do It Yourself” way,
• Code program flow rebuild from Real Time Trace PST/DATA output signals within
the Trace window component (open the Trace component to display the code
program flow rebuild),
Typically, the debugger provides four instruction hardware breakpoints, and one
watchpoint. When setting triggers (A or/and B or/and C), the debugger still allows to set
two instruction hardware breakpoints.
Triggers A and B relate to the program counter, whereas Trigger C relates to memory
operations.

context menu, Trigger A and B can be selected to set breakpoints.
Specific DBG support menu options are added to the Connection menu as soon as the
debugger target processor is acknowledged by the DBG module.
The DBG module Sequencer setup can be set directly via the context sensitive context
menu, “Sequencer Setup” menu entry.
The recording mode can also be set when selecting the “Trace Setup” menu entry.
The “Trigger Module Usage” entry provides a straight-forward way to switch between the
Automatic, User Triggers, Expert, and Profiling/Coverage mode.

This window can be opened from context sensitive context menus in the Source, Data,
Memory and Assembly component windows, from the Connection menu and also when
clicking on a Status Bar displayed mode (Automatic, by default).
The on-chip DBG module can be fully controlled from within this window.
The dialog is designed with three tabs. Trigger Settings is the main tab, where all modes of
the debugger can be selected in the top drop down box.
Figure 31.2 Trigger Module Settings Window - Trigger Settings Tab
Trigger Module Usage/DBG Module Setup
In the Trigger Settings main tab, three modes can be selected to take advantage of the on-
chip DBG module:
•An Automatic mode, which does not provide trigger functionalities, therefore, does
not provide complex breakpoints or complex watchpoints, but typically, four
hardware breakpoints and one watchpoints that can be set as usually via windows
context sensitive context menus or command line commands.
•An Expert mode, which is a “Do It Yourself” interface to set the on-chip DBG
module. In that case, the debugger does not use any on-chip module resources. Refer
to silicon specifications to correctly set up the DBG module. The debugger still
provides the Trace rebuild window and support to display, when available, the results
of the captured data.
![](asset-2b2.png)

•A User Triggers mode, which provides two complex breakpoints, triggers A and B,
one complex watchpoint, trigger C, and two spares classic hardware breakpoints that
can bet as usual (not in the dialog).
•A Profile and Coverage mode, which provides code profiling and coverage
information when opening the Profiler and Coverage components. Note that these
features are not real time. The debugger can only access the DBG on-chip trace
buffer/FIFO when the device is halted. Therefore, in background, the debugger
regularly halts the device, retrieves debug information, then restarts the device, to
build a statistic program counter database. Refer to Profiling and Coverage Mode.
Figure 31.3 General Usage Listbox
Automatic Mode
Automatic provides only two behaviors for the Trace window in the Trace Settings list
menu:
• Disabled: not recording any data and not displaying anything in the Trace window,
• Enabled: recording continuously. Each time the debugger is halted, the Trace
window is refreshed with the latest program flow recorded.

Sync PC DBG Feature
The Sync PC DBG feature forces the DBG module to capture the current program counter
at regular intervals and record this PC in the on-chip DBG buffer/FIFO. This is disabled
by default but is extremely useful when debugging program code loops without changes of
flow. When code loops are executed without traceable information, the DBG module does
not record any data, and the debugger cannot rebuild any program flow in the Trace
window.
To force the DBG module to capture program flow information regardless of the executed
instructions, engage the Sync PC feature using the list menu. The more cycles in the loop
you are debugging, the higher you can set the Sync PC cycle.
Figure 31.5 Sync PC List Menu
NOTE Engaging the Sync PC feature forces the on-chip DBG module to fill its
capture buffer/FIFO with data that is usually not necessary. Using this feature
automatically reduces the amount of change of flow information in the DBG
buffer/FIFO, and restricts program flow rebuild code range in the Trace
window.

TIP Trigger A (only) can be adjusted with a mask on the address, that can be set in the
Mask field when the Enable Mask checkbox is set.
The Trace Settings list menu gives a set of options to choose the way the module is going
to start and to stop recording.

General Settings
Automatically analyze the FIFO content: When the debugger halts for any reason with
the Trace window open, the DBG module results are automatically analyzed and
displayed in the Trace window. If the Trace window is closed, the DBG user interface
performs no result analysis except trigger flags reported in the status bar. Clearing this
check box restricts result analysis even with the Trace window open.
When starting, automatically step if a trigger is set at PC address (otherwise: warn): To
run the application again, the debugger usually needs to exit the trigger current match
condition and avoid being stuck/halted/locked by the trigger. This usually requires a single
step to “escape” from a hardware breakpoint.
Issue warning on attempt to execute with incorrect Sequencer settings: When the on-
chip DBG module sequencer is set up incorrectly, the debugger displays an informative
error message when started.

Flash Programming
Non-Volatile Memory Control Utility
Introduction
Writing to Flash modules, EEPROMs, or other non-volatile memory modules in modern
MCUs requires special algorithms from microprocessor designers. Before you write to
Flash devices, you must erase them. Many Flash devices need initialization to become
accessible; some devices may need write protection removed.
This manual explains the Non-Volatile Memory Control (NVMC) utility, an extension
component that lets you control on-chip Flash devices for all debugger connections.
As it supports many MCUs and Flash modules, the NVMC utility is very flexible. This
flexibility comes from a generic debugger component, which calls a graphical user
interface, then loads an MCU-specific module. The module provides the appropriate
information such as structure, access algorithms, and location for that MCU.
The NVMC utility lists all non-volatile memory devices, indicating their structure, state,
and location. You can change the state (enabled/disabled, blank, programmed, protected/
unprotected) and program data into the modules.
Automated Application Programming
The debugger is able to program an application without making use of the NVMC dialog
box/GUI, which remains useful for specific operations only. Currently, CodeWarrior IDE
projects created from a series of wizard dialog boxes might be programmed/Flashed
immediately. By default, the debugger prompts a warning dialog box to get user
acceptance before mass erasing, then programming the application.
Use the FLASH-specific command (FLASH NOUNSECURE) described in this chapter to
incorporate device security byte programming in user code.
![](asset-2bc.png)

Microcontrollers Debugger Manual
Figure 32.1 Flash Programming Acceptance Dialog Box
Select the OK button to launch background Flash commands. These commands arm
programming, load/program an application file, then disarm programming, and are
described later in this chapter.
Check the Do not display this message anymore for this project checkbox to remove
the Warning message for the current project. The setting is saved in the project under the
project variable: AEFWarningdialog box=FALSE.
Setup
Choose the Load menu entry in the connection debugger menu (for example, HCS08
Open Source BDM) to open the Load Executable File dialog box.
Figure 32.2 Load Executable File Dialog Box option
Check the above option to automatically mass erase the device and program the
application into non-volatile memory (FLASH and/or EEPROM).
To permanently set this option, a check box is available in the Load tab of the debugger
Preferences dialog box, as shown in Figure 32.3. Select the File > Configuration menu
command to display this dialog box.

Advanced Options: Erase Prevention
Select the Advanced button in the Load tab of the debugger Preferences dialog box to open
the following selection dialog box.
Figure 32.4 Programming Selection
The dialog box lists all the non-volatile memory modules registered by the debugger for
the currently selected processor device.
Click once on a line to select an item (highlighted in blue) and click again on a selected
item to deselect it.
Erasing is skipped for all selected modules. If you select all modules, the debugger
programs the application without erasing any non-volatile memory on the device.
CAUTION The debugger ignores pre-programmed modules and the user is
responsible for reprogramming limitations, risks and impossibilities.
However, the debugger displays a warning message when a programmed
(i.e. not blank) “not automatically erased” module is going to be written.
You can disable the displayed warning message.
TIP When available on-chip, EEPROM type modules are by default not selected for
automatic erasing.
The selection dialog box does not give many details about the listed blocks. More
information can be displayed by typing the FLASH command in the Command window, or
by opening the Non-Volatile Memory Control dialog box.
The NVM Programming Selection dialog box is tightly associated with the FLASH
AEFSKIPERASING command of the debugger.

NVMC Graphical User Interface
The NVMC utility is integrated into the debugger as an extension of certain debugger
connections. If the NVMC utility is available, your connection menu includes a Flash
selection.
Figure 32.5 HCS08 Open Source BDM Connection Menu Example
Modules and Module States
In the following sections, the expression available modules means all the FLASH or
EEPROM on-chip modules that the NVMC dialog box lists. The module definitions
correspond with the CPU derivative technical summary and special technical
considerations. If an on-chip module consists of several independent blocks, the NVMC
dialog box might list all of these blocks. However, typically groups the entire non-volatile
on-chip blocks under one single listed module and separates relevant and important non-
volatile memory blocks (such as mirrored non-banked memory range), and provides an
individual/selective module for these.
NOTE Refer to Hardware Considerations for more information about the Flash
modules of your CPU derivative.
Other important expressions are:
•Enabled — An enabled module is a module currently active on the chip. It is
possible to read (as a ROM) or program an enabled module.
![](asset-2bf.png)
Flash Programming
NVMC Graphical User Interface
703
Microcontrollers Debugger Manual
•Disabled — A disabled module is not active on the chip, so programming and
reading are not possible. The usual control for enabling or disabling a module is
setting/clearing a flag in a special register. Note that a few modules always must be
active. You may not disable such modules.
•Blank — A blank module is empty of code: you can program its full address range.
(Each blank byte contains the value 0xFF or 0x00, depending on hardware.)
•Programmed — A programmed module is partially programmed (not all bytes
contain 0xFF or 0x00). You must keep track of the areas still available for
programming, if any.
•Protected — A protected module is partially protected from erasure or programming.
The usual control for protecting a module is setting/clearing a flag in a special
register. Note that a few modules always must be unprotected; you may not protect
such modules.
•Unprotected — An unprotected module can be erased and programmed.
To select a module or other list item, left-click the module. To deselect a module, press the
Ctrl key and left-click. For multiple selections or deselections, use the Shift key.
NVMC Dialog Box
The NVMC dialog box lists all the Flash or EEPROM modules of a CPU derivative. A
derivative such as the MC9S08RC16 or the MCF51QE128 has just one on-chip Flash
module; other derivatives have multiple modules.
NOTE The dialog box does not have a Select or Deselect button, since you simply
click on a module in the list to select it. But selecting and deselecting are not
automatic from the command line. Before you use the command line to
perform any operation on a module, you must use the SELECT command to
select the module. Also see the FLASH SELECT and FLASH UNSELECT
commands in this chapter.
![](asset-2c0.png)
Flash Programming
NVMC Graphical User Interface
704
Microcontrollers Debugger Manual
Figure 32.6 Non-Volatile Memory Control Dialog Box
For each block, the dialog box has a line composed of the following fields:
•Name — the module name
•Start — the module start address
•End — the module end address
•State — the modules states, such as disabled, enabled, blank, programmed,
protected, unprotected
Possible state combinations are:
•Bad Device (the interface was unable to detect a correct device)
•Disabled (one or all modules are disabled)
• [Enabled] / <Blank | Programmed> / [Unprotected | Protected]
The NVMC dialog box displays only meaningful states. For example, it displays Enabled
only if it is possible to disable a module. It displays Unprotected only if it is possible to
protect a module.
The Configuration group identifies the current.FPP parameter file. This group also
includes the Auto select according to MCUID checkbox. The Configuration: FPP
loading section explains this option.
![](asset-2c1.png)
Flash Programming
NVMC Graphical User Interface
705
Microcontrollers Debugger Manual
The second checkbox of the Configuration group is Save and restore workspace
content. If this checkbox is clear, Flash programming applications overwrite any data in
RAM. Check this box to save the current RAM data. Saving RAM data slows down the
NVMC. Checking this checkbox is equivalent to entering the SAVECONTEXT and
LOADCONTEXT commands.
Flash Module Handling
Flash parameter files (which have the extension .FPP) contain MCU-specific parameters,
as well as programs to handle internal Flash modules. The FPP Files section includes
additional information about .FPP files. The .FPP files also include code-applet
descriptions of Flash operations.
You also may use the Command Line component to handle Flash operations. The NVMC
Commands section explains the corresponding commands.
The NVMC dialog box has buttons for commands you can apply to each block. These
buttons are dynamic; active if the operation is possible for at least one selected item,
disabled if the operation is not possible.
• Select All/Unselect All — The Select All button selects all modules in the list box.
After the button is pressed, the button changes to Unselect All, and can be pressed to
remove all current selections.
• Enable/Disable — The Enable button enables all selected modules currently
disabled. The Disable button disables all selected modules currently enabled. The
possibility of enabling or disabling a Flash module depends on the MCU features and
context.
• Protect/Unprotect — The Protect button protects all selected modules currently
unprotected. The Unprotect button unprotects all selected modules currently
protected. The possibility of protecting or unprotecting a Flash module depends on
the MCU features and context.
NOTE For some MCUs, protection is possible only for the Boot section and boot
routines, not for the entire module. Refer to Hardware Considerations for
protection information about your CPU derivative.
•Erase — The Erase button removes any programming from all selected Flash
modules. That is, it assigns the value 0xFF or 0x00 to each byte. Erasure changes the
module status to Blank. If all the selected modules already are blank, the Erase
button is disabled.
• Load — The Load button arms all selected modules, executes a LOAD command,
then disarms the modules. If you click the Load button without selecting any Flash
modules, the NVMC utility selects and loads all modules.

706
Microcontrollers Debugger Manual
NOTE You simply click on a module in the list to select and/or use Select All/
Unselect All buttons to adjust your selection. But selecting and unselecting are
not automatic from the command line. Before you use the command line to
perform any operation on a module, you must use the SELECT command to
select the module. Also see the FLASH SELECT and FLASH UNSELECT
commands in this chapter.
MCU Speed Information
The displayed MCU speed is the device bus speed/clock sensed by the Flash programmer;
same value as the one returned by the FLASH command.
CAUTION A non-relevant displayed speed is symptomatic of a Flash programmer
diagnostic problem. If this occurs, close the dialog box, check the
hardware, and reset the connection.
Configuration: FPP File Loading
When the dialog box is open, the NVMC utility loads the .FPP configuration file
according to this algorithm:
1. The utility reads the NV_PARAMETER_FILE entry from the connection-specific
section of the project.ini file. [HCS08 Open Source BDM] is a connection-
specific section.
Example:
[HCS08 Open Source BDM]
NV_PARAMETER_FILE=C:\MYINSTALL\PROG\FPP\mcu1027.fpp
2. If the utility retrieves a valid .FPP file name, it loads the file.
3. If the utility cannot find a valid .FPP file name, it displays an appropriate error
message.
4. If the utility does not find an entry, or if it finds an empty entry, the utility
automatically checks the Auto select according to MCUID: checkbox. Then the
utility loads the parameter file from the \FPP subdirectory of the CodeWarrior IDE
installation, according to the MCUID.
5. If the utility finds a file that has the wrong format, it displays an appropriate error
message.
6. The utility always displays the MCUID, if the Id is available from the connection.
![](asset-2c3.png)
Flash Programming
NVMC Graphical User Interface
707
Microcontrollers Debugger Manual
Another way to load an .FPP parameter file is by clicking the Browse button. This brings
up a standard Open dialog box, which you can use to select the file. When you do so, the
Open dialog box disappears, and the NVMC utility loads the file, automatically clearing
the Auto select according to MCUID: checkbox. In case of an error during loading, the
utility displays an appropriate message.
Figure 32.7 Open Dialog Box
If you check the Auto select according to MCUID: checkbox, the NVMC utility
searches for and loads the corresponding .FPP parameter file.
Click the OK button to close the NVMC dialog box. If the Auto select according to
MCUID: checkbox is clear, the NVMC utility saves the name of the selected
configuration file under the NV_PARAMETER_FILE entry of the project.ini file. If
you check this checkbox, the utility does not save the .FPP in the project file.
Click the Cancel button to close the dialog box without saving changes.

Loading an Application in Flash
The Load button and the Load menu selection perform the same function. Use either of
these controls to bring up the Load Executable File dialog box, which lets you select the
file to be loaded. The Load Executable File dialog box lists the executable files that relate
to blocks selected in the NVMC dialog box.
Figure 32.8 Load Executable File Dialog Box
If a problem occurs during application loading into Flash, the NVMC utility displays an
error message.

Hardware Considerations
This section consists of hardware-specific information about current .FPP files. New
.FPP file features are explained in release notes.
NOTE The Flash programming release note, in the toolkit installation documentation,
contains the latest information about .FPP files.
HCS08 CPU devices
Typically, one or two Flash modules are listed: FLASH and SMALL_FLASH.
SMALL_FLASH is usually a small block of Flash located below the “High Page
Registers” range. As this range of FLASH is physically linked to the rest of the FLASH,
erasing this block also affects the Flash module, and vice versa. FLASH is the main block
of FLASH above the “High Page Registers” range.
HCS08 CPU devices with banked/paged
EEPROM
As devices described in previous section, FLASH and SMALL_FLASH might be
available.
EEPROM_P0 and EEPROM_P1 are provided to program directly paged EEPROM
ranges. Note that when programming banked/paged EEPROM ranges, programming
addresses must be considered ‘logical’. Erasing one module also erases the other mode.
The setup of EPGMOD bit of FOPT register is not handled.
TIP When available on-chip, EEPROM type modules are by default not selected for
automatic erasing. Refer to Advanced Options: Erase Prevention section.
ColdFire CPU devices
WARNING! Programming ColdFire devices via the NVMC dialog requires proper
device initialization. Otherwise the device speed sensing fails and
programming/erasing cannot be performed correctly. Typically,
program the ColdFire Flash with the Load Executable File dialog box.

NVMC Commands
711
Microcontrollers Debugger Manual
FLASH INIT
<fileName>
|AUTOID loads the parameter file according to
fileName (you can specify the path). If this command includes AUTOID, the MCUID
determines the parameter file (autocheck is checked in the NVMC dialog box).
FLASH RELEASE releases the current FPP file loaded by the Flash programmer.
Therefore the Flash programmer address mapping is disabled and no non-volatile memory
is handled.
FLASH MEMMAP maps the Flash programmer address filtering to route the code for block
programming.
FLASH MEMUNMAP unmaps the Flash programmer address filtering. Programming is
therefore disabled as long as FLASH MEMMAP is not executed.
FLASH ENABLE enables the specified modules. If no modules are specified, all available
blocks are enabled. This command ignores modules that cannot be enabled.
FLASH DISABLE disables the specified modules. If no modules are specified, all
available blocks are disabled. This command ignores modules that cannot be disabled.
FLASH ERASE erases the specified modules. If no modules are specified, all available
blocks are erased.
FLASH AEFSKIPERASING specifies non-volatile memory blocks to protect from mass
erasing during application automated programming. Place the command in a Startup
command file. If no modules are specified, no blocks are erased.
NOTE This command is compatible and replicated in the NVM Programming
Selection dialog box.
FLASH UNPROTECT unprotects the specified modules. If no modules are specified, all
available blocks are unprotected. This command ignores modules that cannot be
unprotected.
FLASH PROTECT protects the specified modules. If no modules are specified, all
available blocks are protected. This command ignores modules that cannot be protected.
FLASH SELECT selects the specified modules for Flash programming. If no modules are
specified, all available blocks for Flash programming are selected.
FLASH UNSELECT deselects the specified modules. If no modules are specified, all
available blocks are unselected. The unselected state protects against accidental Flash
programming.
FLASH ARM prepares the NMVC utility for loading; as does a normal LOAD command.
The system executes the VPPON.CMD file specified in the Command Files user interface.
This command is required before loading FLASH.
FLASH DISARM ends a load process. The system executes the VPPOFF.CMD file
specified in the Command Files user interface.
FLASH SAVECONTEX backs up current SRAM content into a buffer.

Flash Programming
NVMC Commands
712
Microcontrollers Debugger Manual
FLASH LOADCONTEX restores current buffer content into the MCU SRAM.
FLASH OVLBACKUP backups application code overlap with programming runtime/
algorithm (RAM preset for debugging). Execute the command before loading the
application/file.
FLASH OVLRESTORE restores/installs (writes in RAM) the application code overlap
with programming runtime/algorithm. Execute the command after the last FLASH
command.
FLASH PROTOCOLON displays the Flash programmer debug protocol.
FLASH PROTOCOLOFF stops displaying the Flash programmer debug protocol.
FLASH SKIPSTATUSON skips the Flash programmer device Non-Volatile Memory
blocks diagnostic. You can use this command to speed up project application loading and
programming from the IDE debug run. The Flash programmer does NOT verify that
blocks are programmed or erased.
FLASH SKIPSTATUSOFF removes the SKIPSTATUSON mode and therefore
diagnostics are performed again.
FLASH NVMFREQUENCY <frequency in Hz> specifies the Non-Volatile Memory
programming frequency in Hertz; typically the device bus speed after reset. When used,
the Flash programmer does not try to evaluate this speed and the debugger gains 2-3
seconds at application loading time. A value of “0” enables the speed detection.
FLASH NVMIF2RELOCATE Command not relevant for HCS08 devices.
FLASH NVMIF2WORKSPACE Command not relevant for HCS08 devices.
FLASH UNSECURE After device mass erasing, the Flash programmer automatically
programs the device security byte to the “Unsecure” state to enable code debugging
(default behavior).
FLASH NOUNSECURE After device mass erasing, the Flash programmer does not
program the device security byte to the “Unsecured” state. The command must be placed
in a Startup command file, to be executed before any erase operation.
TIP Use this command when the user application contains the code to program the
device security byte. This guarantees that no over-programming is performed on
the Flash security byte cell.
CAUTION If the device security byte is not programmed to the “Unsecured” state,
after the device is reset, debugging is no longer possible until the next
mass erase and security byte is programmed to “Unsecured” state.

Debugging Memory Map
Introduction
The Debugging Memory Map (DMM) is a software Manager handling all debugger
accesses to device/chip memory and also handling memory data caching.
The DMM provides a global approach for all different CPU families/cores, each family
having its own method for memory access and its own memory on-chip layout and
memory address range priorities.
The DMM gets all memory read and write calls from the debugger. On the other side, the
DMM has the very low level function read/write primitives to call third party cable drivers
of BDM pods, Monitors, etc.
For each CPU core, the debugger provides the DMM with core-specific read/write access
methods that are called Types within the DMM Graphical User Interface (GUI), and core-
specific priority rules that are called Priority within the DMM GUI.
Indeed, the DMM has a GUI, therefore providing to the user a way to change memory
access methods at any time.
The DMM GUI
The graphical user interface is flexible enough to be handled without much difficulty, and
live diagnostic is displayed within the dialog. Anytime, it is possible to revert to default
(factory) setup, and most of the time, the user does not even need to edit/change settings
within the DMM GUI.
The DMM GUI can be opened when choosing Debugging Memory Map in the
connection menu entry in the debugger.

Debugging Memory Map
The DMM GUI
716
Microcontrollers Debugger Manual
Figure 33.1 DMM Graphical User Interface
The DMM GUI shows a list of memory address ranges (called Modules in this manual)
defined to access the device/chip memory.
The Type column tells the type of memory for the defined memory address range given in
the Range column. The Active column indicates whether the defined range is active or
mapped by the DMM. If No, the DMM treats the range as if it is not defined at all.
NOTE All undefined ranges are considered by the DMM as inaccessible or
unimplemented. The debugger displays some "--" in the Memory window in
that case, and the DMM NEVER attempts to read or write unimplemented
memory.
The Comment column contains a text information comment about the defined memory
address range.
The Information scrollable window gives a general diagnostic of the DMM: This
diagnostic has less information than the edition mode diagnostic.
Pressing the New button opens the edition dialog to create a new memory address range.
Pressing the Modify/Details button opens the edition dialog of the selected memory
address range to modify it or to see more setup details. More memory range information is
displayed in the edition dialog, and an enhanced diagnostic is also displayed.
Pressing the Delete button removes the memory range, after a warning dialog.

Microcontrollers Debugger Manual
Pressing the Revert to Default button removes (after a warning dialog) the current setup
(usually saved in the current project) and retrieves the default (factory) setup from an
internal database.
Edition dialog and memory range edition
Figure 33.2 shows the DMM Memory map dialog box.
Figure 33.2 DMM Memory Address Range Edition Dialog box
The Enable memory module option checkbox maps the module/memory range in the
debugger. Unchecking this option makes the module completely transparent for the DMM
and the debugger.
The Start edit box contains the first address of a memory range and the End edit box
contains the last address of a memory range.
Range boundaries are always limited to an overlapped range with a bigger priority.
For example, if 2 bytes are defined in a range which overlaps another range, accessing
these 2 bytes is performed using the type and rules of this 2-byte range. The memory on
both sides of these 2 bytes is accessed using the type and rules of the overlapped range.
NOTE The Start–End range is a range address for a Type and for a Priority.
Internally, ranges can overlap only if they are of the same type and of the same
priority. The debugger always reads with rules of the range with the highest
priority.

718
Microcontrollers Debugger Manual
Access kind
The Access Kind list menu provides a way to indicate that the memory range is read/write
(R/W), read only, write only or none of these.
When defined as read only, the range is never written by the debugger.
When defined as write only, the range is never read by the debugger.
When defined as none, the range is never read or written by the debugger. This is internal
equivalent as not defining the range in the DMM dialog.
Access Size
When available, the Access Size list menu provides a way to define if the memory range is
accessed as byte (1), short (2) or long (4).
NOTE The memory range must be size aligned. For example, a module defined with
access size 2 must start with an even address and finish on an odd address. A
module defined with access size 4 must start with an address with the least
significant byte in 0, 4, 8, C, and finish with an address with the least
significant byte in 3, 7, B, F.
NOTE A memory range overlapping (in priority) another memory range can only have
the same or a higher access size.
Types
The Type list menu provides all kinds of memory types available for the processor
displayed in the title bar of the dialog. For some connections, the CPU core might be
displayed instead of the processor name.
Types are internal rules to read and write a kind of memory. For examples, the HCS08
banked type requires first setting a register called PPAGE to read the memory, then
restoring this value as it was before reading. Also this banked type does not physically
provide a memory access while running. Memory access while running is possible in
physical memory (RAM, registers).

NOTE CPU core-specific memory types and Priorities are listed at the end of this
section.
Priorities
The Priority list menu provides all types of memory overlap priorities available for a
processor core. The debugger can have a bigger priority (highest (debugger)) to set an
upper address range that can overlap an on-chip address range. This makes a debugger
display filter (for a Memory window), e.g. when creating a No read access while running
memory address range.
A Flat memory architecture (i.e., without memory blocks moving feature) provides the
following Priority list menu (e.g. HCS08 and ColdFire cores):
Figure 33.4 HCS08 or ColdFire Core Priorities
When left at the default setting, the CPU treats all memory block with the same priority.

Memory Read Caching
The Refresh memory when halting option controls the debugger memory cache. When
this option is checked, internal images/caches of memory data are always deleted and the
data is always retrieved from hardware when required by the debugger. When unchecked
(usually by default for Non-Volatile Memory areas), the DMM keeps a copy of the data
and does not read or retrieve the data from hardware until next application loading/
programming.
NOTE Each declared memory address range in the GUI has its own private code cache
monitored by the DMM.
TIP The DMM CACHINGOFF command can fully disable the caching feature for the
entire DMM, that is, for all defined memory ranges. The DMM CACHINGON
command re-enables the caching feature.
Access while Running
Use the No memory access while running option to discard debugger access to a
memory range, typically accessed while running. This feature is useful to protect on-chip
I/O Register flags from being triggered by debugger memory reads due to display
refreshes.
Remarks
It is possible to create as many memory ranges as wanted, down to a single byte.
Deleting Default/Factory ranges generates warning dialogs. Some settings are required for
the debugger to debug and removing ranges leads to erroneous debugging information.
All GUI settings can be done by debugger commands.
Settings and DMM changes are saved in the current user project. The user can always
restart from draft pressing the Revert to Default button.
Automatic DMM range remapping can be disabled by a debugger command.
The default settings are retrieved from a complete database describing each derivative, or,
in some cases, describing the CPU core (when not necessary to go to derivative level).

CPU Core Types and Priorities
This section details the available cores and their respective types and priorities.
HCS08 CPU
The following types and priorities are available for the HCS08 CPU.
Priorities:
•highest (debugger): a high debugger priority that can be used by the user or defined
for the debugger, typically to protect a memory area from being read.
•default (device): default CPU visibility of the entire device/memory with the same
priority, so no memory range can be moved to overlap another memory range.
•lowest (debugger): a low debugger priority that can be used by the user or defined
for the debugger typically to protect a memory area from being read. This priority is
of poor usage but can still be used for display purposes on chip unimplemented
memory range.
Types:
•LAP Registers: This mode is only available for HCS08 devices with an on-chip
MMU. This sets the memory range as special on-chip LAP registers. Typically, a
specific range is already preset with this type so you do not need to use this type.
•linear: This mode is only available for HCS08 devices with an on-chip MMU. This
sets the memory as linear address space (also called Extended Address); range
typically addressed by the on-chip linear address pointer.
•physical: this sets the memory range as physical, i.e. with local 16-bit address bus
access as performed by the CPU when reading and writing the on-chip memory.
•banked: This mode is only available for HCS08 devices with an on-chip MMU. This
sets the memory as banked (i.e., accessed in the PPAGE window ($8000-$BFFF)
with PPAGE register handling). The banked type provides the debugger logical
display of the memory. A range defined as banked is displayed in the Memory
window with a physical/local address in addition to PPAGE << 16. This logical
address is therefore only valid in the $8000-$BFFF window. For example, an
instruction address at $8050 in PPAGE $03 is visible in the Memory window at
$038050.
•EEPROM banked: This mode is only available for HCS08 devices with an on-chip
EEPROM module having several pages. A range defined as EEPROM banked is
displayed in the Memory window with a physical/local address in addition to the
bit(s) to switch EEPROM pages << 16. This logical address is therefore only valid
in the EEPROM range window.

722
Microcontrollers Debugger Manual
NOTE By factory/default setup, HCS08 DBG08 Fifo Registers have been protected to
reserve the DBG08 Fifo Reading for the debugger DBG interface. Removing
this protection leads to incorrect program flow rebuild.
ColdFire CPU
The following types and priorities are available for the ColdFire CPU.
Priorities:
•highest (debugger): a high debugger priority that can be used by the user or defined
for the debugger; typically used to protect a memory area from being read.
•default (device): default CPU visibility of the entire device/memory with the same
priority, so no memory range can be moved to overlap another memory range.
•lowest (debugger): a low debugger priority that can be used by the user or defined
for the debugger typically to protect a memory area from being read. This priority is
of poor usage but can still be used for display purposes on chip unimplemented
memory range.
Types:
•physical: this sets the memory range as physical, i.e. with linear 32-bit address bus
access as performed by the CPU when reading and writing the on-chip memory.
DMM Commands
All DMM GUI settings can be done by debugger command line commands.
Debugging Memory Map Manager
command set
The commands allow the user to fully script the debugging device memory mapping.
Limit the usage of these commands to special debugging purposes, as the default mapping
is typically sufficient. A script setup may be complex and may lead to debugger
malfunctions.

Commands
Commands Overview
The debugger supports scripting with the use of commands and command files. When you
script the debugger, you can automate repetitive, time-consuming, or complex tasks.
You do not need to use or have knowledge of commands to run the Simulator/Debugger.
However these commands are useful for editing debugger command files, for example,
after a recording session, to generate your own command files, or to set up your
applications and targets, etc.
This section provides a detailed list of all Simulator/Debugger commands. All command
names and component names are case insensitive. The command EBNF syntax is:
component [:component number] < ] command
where component is the name of the window component. For example: Data, Register,
Source, Assembly, etc. Component number is the number of the component. This
number does not exist in the component window title if only one component of this type is
open. For example, if you open a second Memory component window, the initial Memory
component window is renamed Memory:1 and the new one is called Memory:2. A
number is automatically associated with a component if there are several components of
the same type displayed.
Command Example:
in>Memory:2 < SMEM 0x8000,8
‘<‘ redirects a command to a specific component (in this example: Memory:2). Some
commands are valid for several or all components; if the command is not redirected to a
specific component, all components are affected. Also, a mismatch can occur because a
command’s parameters may differ for different components.

Available Command Lists
Commands described on the following pages are sorted into 5 groups, according to their
specific actions or targets. However, these groups have no relevance in the use of these
commands. A list of all commands in their respective group is given below.
Kernel Commands
Kernel commands are commands that can be used to build command programs. They can
only be used in a debugger command file, since the Command Line component can only
accept one command at a time. It is possible to build powerful programs by combining
Kernel commands with Base commands, Common commands and Component specific
commands. Table 34.1 contains all available Kernel commands.

Command Syntax Terms
address
A number matching a memory address. This number must be in the ANSI format (i.e. $ or
0x for hexadecimal value, 0 for octal, etc.).
Example: 255, 0377, 0xFF, $FF
NOTE address can also be an expression if constant address is not specifically
mentioned in the command description. An expression can be: Global variables
of application, I/O registers defined in DEFAULT.REG, definitions in the
command line, or numerical constants.
Example: DEFINE IO_PORT = 0x210
WB IO_PORT 0xFF
range
A composition of two addresses to define a range of memory addresses. Syntax is shown
below:
address...address
or
address, size
where size is an ANSI format numerical constant.
Example:
0x2F00...0x2FFF
Refers to the memory range starting at 0x2F00 and ending at 0x2FFF (256 bytes).
Example:
0x2F00,256
Refers to the memory range starting at 0x2F00, which is 256 bytes wide. Both previous
examples are equivalent.
fileName
A DOS file name and path that identifies a file and its location. The command interpreter
does not assume any file name extension. Use backslash (\) or slash (/) as a directory
delimiter.
The parser is case insensitive. If no path is specified, it looks for (or edits) the file in the
current project directory. When no path is specified, the default directory is the project
directory.

component
The name of a debugger component. A list of all debugger components is given by
choosing Component > Open. The parser is case insensitive.
Example:
Memory
Example:
SoUrCe
Module Names
Correct module names are displayed in the Module component window. Make sure that
the module name of a command that you implement is correct:
If the .abs is in HIWARE format, some debug information is in the object file (.o), and
module names have a .o extension (e.g., fibo.o).
In ELF format, module name extensions are .c, .cpp or .dbg (.dbg for program
sources in assembler) (e.g., fibo.c), since all debugging information is contained in the
.abs file and object files are not used.

The COLUMNWIDTH command sets the width of one column entry on the right
pane of the Inspector Window. The first parameter (columnname) specifies which
column. The following column names currently exist:
• Names - simple name list
• Interrupts - interrupt list
• SymbolTableFunction - function in the Symbol Table
• ObjectPoolObject - Object in Object Pool without additional information
• Events - event list
• Components - component list
• SymbolTableVariable - variable or differentiation in the Symbol Table
• ObjectPoolIOBase - Object in Object Pool with additional information
• SymbolTableModules - non IOBase derived Object in the Object Pool
The column field is the name of the specific field, which is also displayed in the
Inspector Window.
The following commands set the width of the function names to 100:
inspect < ATTRIBUTES COLUMNWIDTH SymbolTableModules Name
100
NOTE Due to the “inspect <“ redirection, only the Inspector handles this command.
The EXPAND command computes and displays all subitems of a specified item up
to a given depth. An item is specified by specifying the complete path starting at
one of the root items like “Symbol Table” or “Object Pool”. Names with spaces
must be surrounded by double quotes.
To expand all subitems of TargetObject in the Object Pool up to four levels,
the following command can be used:
inspect < ATTRIBUTES EXPAND “Object Pool” TargetObject 4
NOTE Because the name Object Pool contains a space, it must be surrounded by
double quotes.
NOTE The symbol Table, Stack or other Items may have recursive information. So it
may occur that the information tree grows with the depth. Therefore,
specifying large expand values may use a large amount of memory.

The SPLIT command sets the position of the split line between the left and right
pane. The value must be between 0 and 100. A value of 0 only shows the right
pane, a value of 100 shows the left pane. Any value between 0 and 100 makes a
relative split. The following command makes both panes the same size:
inspect < ATTRIBUTES SPLIT 50
The MAXELEM command sets the number of subitems to display. After the
following command, the Inspector prompts for 1000 subitems:
inspect < ATTRIBUTES MAXELEM ON 1000

BS address| function [{mark}]
[P|T[ state]][;cond=”condition”[ state]]
[;cmd=”command”[ state]][;cur=current[ inter=interval]]
[;cdSz=codeSize[ srSz=sourceSize]]
address is the address where the breakpoint is to be set. This address is specified in
ANSI C format. address can also be replaced by an expression as shown in the
example below.
function is the name of the function in which to set the breakpoint.
mark (displayed mark in Source component window) is the mark number where
the breakpoint is to be set. When mark is:
• > 0: the position is relative to the beginning of the function.
• = 0: the position is the entry point of the function (default value).
• < 0: the position is relative to the end of the function.
P, specifies the breakpoint as a permanent breakpoint.
T, specifies the breakpoint as a temporary breakpoint. A temporary breakpoint is
deleted once it is reached.
State is E or D where E is for enabled (state is set by default to E if nothing is
specified), and D is for disabled.
condition is an expression. It matches the Condition field in the Controlpoints
Configuration window for a conditional breakpoint.
command is any Debugger command (at this level, the commands G, GO and
STOP are not allowed). It matches the Command field in the Controlpoints
Configuration window, for associated commands. For the Command function, the
states are E (enabled) or C (continue).
current is an expression. It matches the Current field (Counter) in the
Controlpoints Configuration window, for counting breakpoints.
interval is an expression. It matches the Interval field (Counter) in the
Controlpoints Configuration window, for counting breakpoints.
codeSize is an expression. It is usually a constant number to specify (for security)
the code size of a function where a breakpoint is set. If the size specified does not
match the size of the function currently loaded in the .ABS file, the breakpoint is
set but disabled.
sourceSize is an expression. It is usually a constant number to specify (for
security) the source (text) size of a function where a breakpoint is set. If the size
specified does not match the size of the function in the source file, the breakpoint is
set but disabled.

DECODE_SKIP
In the HC08 CPU and HCS08 CPU components, the DECODE_SKIP command defines
usage of SKIP/SKIP2 pseudo instructions.
NOTE The compiler generates these pseudo instructions by default in order to
optimize code size and speed.
Usage
DECODE_SKIP NO | SKIP | ALL | INFO
Where:
•NO decodes BRN and CPHX #xxxx instructions as is
•SKIP decodes BRN as SKIP pseudo instruction (default)
•ALL decodes BRN as SKIP and CPHX #xxxx as SKIP2 pseudo instructions
•INFO provides information if BRN is decoded as SKIP and if CPHX #xxxx is
decoded as SKIP2

DEFINE
The DEFINE command creates a symbol and associates the value of an expression with
it. Arithmetic expressions are evaluated when the command is interpreted. The symbol can
be used to represent the expression until the symbol is redefined, or undefined using the
UNDEF command. A symbol is a maximum of 31 characters long. In a command line, all
symbol occurrences (after the command name) are substituted by their values before
![](asset-305.png)
Debugger Engine Commands
Debugger Commands
773
Microcontrollers Debugger Manual
processing starts. A symbol cannot represent a command name. Note that a symbol
definition precedes (and hence conceals) a program variable with the same name.
Defined symbols remain valid when a new application is loaded. An application variable
or I/O register can be overwritten with a DEFINE command.
NOTE This command can be used to assign meaningful names to expressions, which
can be used in other commands. This increases the readability of command
files and avoids re-evaluation of complex expressions.
Usage
DEFINE symbol [=] expression
Components
Debugger engine.
Example:
in>DEFINE addr $1000
in>DEFINE limit = addr + 15
First addr is defined as a constant equivalent to $1000. Then limit is defined and
affected with the value ($1000 + 15)
A symbol defined in the loaded application can be redefined on the command line
using the DEFINE command. The symbol defined in the application is not
accessible until an UNDEF on that symbol name is detected in the command file.

FOR
The FOR loop allows you to execute all commands up to the trailing ENDFOR a
predefined number of times. The bounds of the range and the optional steps are evaluated
at the beginning. A variable (either a symbol or a program variable) may be optionally
specified, which is assigned to all values of the range that are met during execution of the
for loop. If a variable is used, it must be defined before executing the FOR command,
with a DEFINE command.
Assignment happens immediately before comparing the iteration value with the upper
bound. The variable is only a copy of the internal iteration value, therefore modifications
on the variable don't have an impact on the number of iterations.
This command can be stopped by pressing the Esc key.
Usage
FOR[variable =]range [“,” step]
Where variable is the name of a defined variable.
range: This is an address range constant that specifies addresses to be

The conditional commands (IF, ELSEIF, ELSE and ENDIF) allow you to execute
different sections depending on the result of the corresponding condition. The conditional
command may be nested. Conditions of the IF and ELSEIF commands, respectively,
guard all commands up to the next ELSEIF, ELSE or ENDIF command on the same
nesting level. The ELSE command guards all commands up to the next ENDIF command
on the same nesting level. Any occurrence of a subcommand not in sequence of “IF, zero
or more ELSEIF, zero or one ELSE, ENDIF” is an error.

LF
The LF command initiates logging of commands and responses to an external file or
device. While logging remains in effect, any line that is appended to the command
window is also written to the log file.
Logging continues until a close log file (NOLF) command is executed. When the LF
command is entered with no filename, the Open File dialog box is displayed to specify a
filename.
Use the logging option (LOG) command to specify information to be logged.
If a path is specified in the file name, this path must be a valid path. When a relative path
is specified, ensure that the path is relative to the project directory.
Usage
LF [fileName][;A]
fileName is a DOS filename that identifies the file or device where the log is
written. The command interpreter does not assume a filename extension.
;A opens the file in append mode. Logged lines are appended at the end of an
existing log file.
If the ;A option is omitted and fileName is an existing file, the file is cleared before
logging begins.
Components
Debugger engine.
Example
in>lf /mcuez/demo/logfile.txt ;A
The logfile.txt file is opened as a Log File in “append” mode.
NOTE If no path is specified, the destination directory is the current project directory.

LS
In the Command Line window, the LS command lists the values of symbols defined in the
symbol table and by the user. There is no limit to the number of symbols that can be listed.
The size of memory determines the symbol table size. Use the DEFINE command to
define symbols, and the UNDEF command to delete symbols.
The symbols that are listed with the LS command are split in two parts: Applications
Symbols and User Symbols.
Usage
LS [symbol | *][;C|S]
Where symbol is a restricted regular expression that specifies the symbol whose
values are to be listed.
* specifies to list all symbols.
;C specifies to list symbols in canonical format, which consists of a DEFINE
command for each symbol.

MS
The MS command sets a specified block of memory to a specified list of byte values.
When the range is wider than the list of byte values, the list of byte values is repeated as
many times as necessary to fill the memory block.
When the range is not an integer multiple of the length of the list, the last copy of the list
is truncated appropriately. This command is identical to the write bytes (WB) command.
Usage
MS range list
range: is an address range constant that defines the block of memory to be set to
the values of the bytes in the list.
list: is a list of byte values to be stored in the block of memory.
Components
• Debugger engine.
Example:
in>MS 0x1000..0x100F 0xFF
The memory range between addresses 0x1000 and 0x100F is filled with the 0xFF
value.
NB
Description
The NB command changes or displays the default number base for the constant values in
expressions. The initial default number base is 10 (decimal) and can be changed to 16
(hexadecimal), 8 (octal), 2 (binary) or reset to 10 with this command. The base is always
specified as a decimal constant.
Independent of the default base number, the ANSI C standard notation for constant is
supported inside an expression. That means that independent of the current number base
you can specify hexadecimal or octal constants using the standard ANSI C notation shown
in Table 34.6.
![](asset-326.png)
Debugger Engine Commands
Debugger Commands
806
Microcontrollers Debugger Manual
Usage
NB [base]
Where base is the new number base (2, 8, 10 or 16).
Components
Debugger engine.
Table Example:
0x2F00, /* Hexadecimal Constant */
043, /* Octal Constant */
255 /* Decimal Constant */
In the same way, the Assembler notation for constant is also supported. That
means that independent of the current number base you can specify hexadecimal,
octal or binary constants using the Assembler prefixes shown in Table 34.7.
Table Example:
$2F00, /* Hexadecimal Constant */
@43, /* Octal Constant */
%10011 /* Binary Constant */
When the default number base is 16, constants starting with a letter A, B, C, D, E
or F must be prefixed either by 0x or by $, as shown in Table 34.8. Otherwise, the
command line interpreter cannot detect if you are specifying a number or a symbol.

The Coverage output results are redirected to the file myfile.txt from the
directory C:\Program Files\Freescale.
P
The P command executes a CPU instruction, either at a specified address or at the current
instruction, (pointed to by the program counter). This command traces through subroutine
calls, software interrupts, and operations involving the following instructions (two are
target specific):
• Branch to SubRoutine (BSR)
• Long Branch to Subroutine (LBSR)
• Jump to Subroutine (JSR)
• Software Interrupt (SWI)
• Repeat Multiply and Accumulate (RMAC)
For example: if the current instruction is a BSR instruction, the subroutine is executed,
and execution stops at the first instruction after the BSR instruction. For instructions that
are not in the above list, the P and T commands are equivalent.
When the instruction specified in the P command has been executed, the software displays
the content of the CPU registers, the instruction bytes at the new value of the program
counter and a mnemonic disassembly of that instruction.

RD
The RD command displays the content of specified registers. The display of a register
includes both the name and hexadecimal representation. If the specified register is not a
CPU register, then it looks for this register in a register file as an I/O register. This file is
called: MCUIxxxx.REG (where xxxx is a number related to the MCU).
NOTE This command is processor/derivative specific and does not display banked
registers if the processor does not support banking.
Usage
RD { <list> | CPU | * }
where list is a list of registers to be displayed. Registers to be displayed are
separated by a space. When RD CPU is specified, all CPU registers are displayed.
If no CPU is loaded, No CPU loaded is displayed as an error message.
When * is specified, the RD command lists the content of the register file that is
currently loaded. If no register file is loaded, following error message is displayed:
No register file loaded.
When there is no parameter, the previous RD command is processed again. If there
is no previous RD command, all CPU registers are displayed.
If list is omitted, the list and any other parameters of the previous RD command
are used.
For the first RD command of a session, all CPU registers are displayed.

RETURN
The RETURN command terminates the current command processing level (returns from
a CALL command). If executed within a command file, control is returned to the caller of
the command file (i.e. the first instance that did not chain execution).
Usage
RETURN
Components

Example:
In file d:\demo\cmd1.txt:
...
CALL d:\demo\cmd2.txt
T
...
In file d:\demo\cmd2.txt

RETURN // returns to the caller
The command file cmd1.txt calls a second command file cmd2.txt. It is so
necessary to insert the RETURN instruction to return to the caller file. Then the T
Trace instruction is executed.
RS
The RS command assigns new values to specified registers. The RS mnemonic is
followed by register name and new value(s).
An equal sign (=) may be used to separate the register name from the value to be assigned
to the register; otherwise they must be separated by a space. The contents of any number
of registers may be set using a single RS command. If the specified register is not a CPU
register, then the register is searched in a register file as an I/O register. This file is called:
MCUIxxxx.REG (where xxxx is a number related to the MCU).

SAVE
The SAVE command saves a specified block of memory to a specified file in Freescale S-
record format. The memory block can be reloaded later using the load S-record (SREC)
command.
NOTE If no path is specified, the destination directory is the current project directory.
Usage
SAVE range fileName [offset][;A]
offset: an optional offset to add or subtract from addresses when writing S-records.
The default offset is 0.
;A: appends the saved S-records to the end of an existing file. If this option is
omitted, and the file specified by fileName exists, the file is cleared before saving
the S-records.
Components
Debugger engine.
Example:
in>SAVE 0x1000..0x2000 DUMP.SX ;A
The memory range 0x1000...0x2000 is appended to the DUMP.SX file.
SAVEBP
The SAVEBP command saves all breakpoints of the currently loaded .ABS file into the
matching breakpoints file. Also, the matching file has the name of the loaded .ABS file
but its extension is .BPT. (For example, the Fibo.ABS file has a breakpoint file called
FIBO.BPT. This file is generated in the same directory as the .ABS file, when the user
quits the Simulator/Debugger or loads another .ABS file.)

Each section of the Debugger manual includes information to help you become more
familiar with the Debugger, to use all its functions and help you understand how to use the
environment. This book, the Debugger Environment Variables, defines the HC08 and

Environment Variables
This chapter describes the environment variables that the Debugger uses. Other tools, such
as the Linker, also use some of these environment variables. For more information about
other tools, see their respective manuals.
Topics include:
•Debugger Environment
•Local Configuration File (usually project.ini)
•ABSPATH: Absolute Path
•DEFAULTDIR: Default Current Directory
•ENVIRONMENT=: Environment File Specification
•GENPATH: #include “File” Path
•LIBRARYPATH: ‘include <File>’ Path
•OBJPATH: Object File Path
•TMP: Temporary directory
•USELIBPATH: Using LIBPATH Environment Variable
•Search Order for Source Files
•Debugger Files

Debugger Engine Environment Variables
Debugger Environment
842
Microcontrollers Debugger Manual
Debugger Environment
Various parameters of the Debugger may be set using environment variables. The syntax
is always the same:
Parameter = KeyName "=" ParamDef.
NOTE Do not use blanks in the definition of an environment variable.
For example:
GENPATH=C:\INSTALL\LIB;D:\PROJECTS\TESTS;/usr/local/lib;/
home/me/my_project
The Debugger parameters may be defined in several ways:
• Using system environment variables supported by your operating system.
• Putting the definitions in a file called DEFAULT.ENV in the default directory.
NOTE The maximum length of environment variable entries in the DEFAULT.ENV/
.hidefaults is 4096 characters.
• Putting definitions in a file given by the value of the system environment variable
ENVIRONMENT.
NOTE The default directory mentioned above can be set by using the system
environment variable DEFAULTDIR: Default Current Directory.
When looking for an environment variable, all programs first search the system
environment, then the DEFAULT.ENV file and finally the global environment file given
by ENVIRONMENT. If no definition can be found, a default value is assumed.
NOTE Ensure that no spaces exist at the end of environment variables.
The Current Directory
The most important environment for all tools is the current directory. The current
directory is the base search directory where the tool begins to search for files (for example,
the DEFAULT.ENV/.hidefaults file)
Normally, the current directory of a tool is determined by the operating system or program
that launches another one (for example, WinEdit).
For MS Windows-based operating systems, the current directory definition is more
complex.
![](asset-34b.png)
Debugger Engine Environment Variables
Debugger Environment
843
Microcontrollers Debugger Manual
• If the tool is launched using a File Manager/Explorer, the current directory is the
location of the executable launched.
• If the tool is launched using an Icon on the Desktop, the current directory is the one
specified and associated with the Icon.
• If the tool is launched by dragging a file on the icon of the executable under
Windows 2000, the desktop is the current directory.
• If the tool is launched by another tool with its own current directory specified (for
example, WinEdit), the current directory is the one specified by the launching tool
(for example, current directory definition in WinEdit).
• For the Debugger tools, the current directory is the directory containing the local
project file. Changing the current project file also changes the current directory, if the
other project file is in a different directory. Note that browsing for a C file does not
change the current directory.
To overwrite this behavior, the environment variable DEFAULTDIR: Default Current
Directory may be used.
Global Initialization File (MCUTOOLS.INI - PC
Only)
All tools may store global data in MCUTOOLS.INI. The tool first searches for this file in
the directory of the tool itself (path of executable). If there is no MCUTOOLS.INI file in
this directory, the tool looks for the file in the MS Windows installation directory (for
example, C:\WINDOWS).
Example:
C:\WINDOWS\MCUTOOLS.INI
D:\INSTALL\PROG\MCUTOOLS.INI
If a tool is started in the D:\INSTALL\PROG\DIRECTORY, the project file in the same
directory as the tool is used (D:\INSTALL\PROG\MCUTOOLS.INI).
If the tool is started outside the D:\INSTALL\PROG directory, the project file in the
Windows directory is used (C:\WINDOWS\MCUTOOLS.INI).
NOTE For more information about MCUTOOLS.INI entries, see the compiler
manual.
![](asset-34c.png)
Debugger Engine Environment Variables
Local Configuration File (usually project.ini)
844
Microcontrollers Debugger Manual
Local Configuration File (usually project.ini)
The Debugger does not change the default.env file. Its content is read only. All
configuration properties are stored in the configuration file. The same configuration file
can be used by different applications.
The shell uses the configuration file with the name project.ini in the current
directory only. That is why this name is also suggested to be used with the Debugger. Only
when the shell uses the same file as the compiler, the editor configuration written and
maintained by the shell can be used by the Debugger. Apart from this, the Debugger can
use any file name for the project file. The configuration file has the same format as
windows .ini files. The Debugger stores its own entries with the same section name as
in the global mcutools.ini file.
The current directory is always the directory containing the configuration file. If a
configuration file in a different directory is loaded, then the current directory also changes.
When the current directory changes, the default.env file is reloaded. Always when a
configuration file is loaded or stored, options in the environment variable
COMPOPTIONS are reloaded and added to the project options. Beware of this behavior
when a different default.env file exists in different directories, which contain
incompatible options in COMPOPTIONS.
When a project is loaded using the first default.env, its COMPOPTIONS are added
to the configuration file. If this configuration is stored in a different directory, where a
default.env file exists with incompatible options, the Debugger adds options and
marks the inconsistency. Then a message box appears to inform the user that the
default.env options were not added. In such a situation the user can either remove the
option from the configuration file with the option settings dialog box or remove the option
from default.env with the shell or a text editor, depending on which options are
needed in the future.
At startup there are three ways to load a configuration:
• use the command line option prod
•the project.ini file in the current directory
• or Open Project entry from the file menu.
If the option prod is used, then the current directory is the directory in which the project
file is located. If prod is used with a directory, the project.ini file in this directory is
loaded.

Microcontrollers Debugger Manual
Default Layout Configuration (PROJECT.INI)
The default layout activated when starting the Debugger is defined in the PROJECT.INI
file located in the project directory, as shown in Listing 35.1. All default layout-related
parameters are stored in section [DEFAULTS].
Listing 35.1 Example Content of PROJECT.INI:
[HI-WAVE]
Window0=Source 0 0 60 30
Window1=Assembly 60 0 40 30
Window2=Procedure 0 30 50 15
Window3=Terminal 0 45 50 15
Window4=Register 50 30 50 30
Window5=Memory 50 60 50 30
Window6=Data 0 60 50 15
Window7=Data 0 75 50 15
Target=Sim
Target: Specifies the target used when starting the Debugger (loads the file <target> with
a .tgt extension), for example, Target=Sim for HC(S)08 Freescale Full Chip Simulator,
or Target=Motosil, Target=Bdi.
Window<n>: Specifies coordinates of the windows that must be open when the Debugger
is started. The syntax for a window is:
Window<n>=<component> <XPos> <YPos> <width> <height>
where n is the index of the window. This index increments for each window and
determines the sequence in which windows open. In the case of overlapping windows, this
index determines which windows appear on top of other windows. Values for the index
must be in the range 0–99.
Component specifies the component type to open, for example, Source, Assembly.
XPos specifies the X coordinate of the top left corner of the component (in percentage
relative to the width of the main application client window).
YPos specifies the Y coordinate of the top left corner of the component (in percentage
relative to the height of the main application client window).
width specifies the width of the component (in percentage relative to the width of the
main application client window).
height specifies the height of the component (in percentage relative to the height of the
main application client window).

Example:
Window5=Memory 50 60 50 30
Window number 5 is a Memory component, its starting position is at: 50% from main
window width, 60% from main window height. Its width is 50% from main window width
and its height 30% from main window height.
Other Parameters
• It is possible to load a previously saved layout from a file by inserting the following
line in your PROJECT.INI file:
Layout=<LayoutName>
Where LayoutName is the name of the file describing the layout to be loaded, for
example, Layout=lay1.hwl
NOTE The layout path can be specified if the layout is not in the project directory.
NOTE If Layout is defined in PROJECT.INI, the Layout parameter overwrites any
Window<n> definition, describing the default windows layout.
• It is possible to load a previously saved project from a file by inserting the following
line in your PROJECT.INI file:
Project=<ProjectName>
where ProjectName is the name of the file describing the project to be loaded,
for example, Project=Proj1.hwc
NOTE The project path can be specified if the project is not in the project directory.
This option can be used for compatibility with the old .hwp format
(Project=oldProject.hwp) and opens as a new project file.
See File Menu section for more details about Projects.
NOTE If Layout and Project are defined in PROJECT.INI, the Project parameter
overwrites the Layout parameter, also containing layout information.
MainFrame=<nbr.>,<nbr.>,<nbr.>,<nbr.>,<nbr.>,<nbr.>,
<nbr.>,<nbr.>,<nbr.>,<nbr.>
This variable is used to save and load the Debugger main window states: positions, size,
maximized, minimized, display icons when opened, etc. This entry is used for internal
purposes only.

• The toolbar, status bar, heading line, title bar and small border can be specified in the
default section:
– The toolbar can be shown or hidden with the following syntax:
Toolbar = (0 | 1)
If 1 is specified, the toolbar is shown, otherwise the toolbar is hidden.
– The status bar can be shown or hidden with the following syntax:
Statusbar = (0 | 1)
If 1 is specified, the status bar is shown, otherwise the toolbar is hidden.
– Title bars can be shown or hidden with the following syntax:
Hidetitle = (0 | 1)
If 1 is specified, the title bars are hidden, otherwise they are shown.
– The heading lines can be shown or hidden with the following syntax:
Hideheadlines = (0 | 1)
If 1 is specified, the heading lines are hidden otherwise they are shown.
– The border can be reduced with the following syntax:
Smallborder = (0 | 1)
If 1 is specified, borders are thin otherwise they are normal.
• The environment variable BPTFILE authorizes the creation of breakpoint files; they
may be enabled or disabled. All breakpoints of the currently loaded .abs file are
saved in a breakpoints file. BPTFILE may be ON (default) or OFF. When ON,
breakpoint files are created. When OFF, breakpoint files are not created.
BPTFILE =(On | Off)
NOTE Target specific environment variables can also be defined in the
PROJECT.INI file. Refer to the specific target manual for details.
Ini File Activation
When a project file (PROJECT.INI) is activated, the following occurs (from first action
to last):
• The old Project file is closed.
• Target Component is unloaded
• The environment variable (Path) is added from the Project file.

Select HI-WAVE section to retrieve value from:
• if an entry Windows0 or Target can be retrieved from section [HI-WAVE] then:
use [HI-WAVE]
• else if an entry Windows0 or Target can be retrieved from section [DEFAULTS]
then:
use [DEFAULTS]
•else:
use [HI-WAVE]
The environment variables are loaded from the default.env file:
• If an entry Layout=lll exists, the layout file lll.hwl is loaded and executed.
• The target is set (if entry Target=ttt exists load target ttt).
• If an entry Project=ppp exists, the command file ppp is executed.
• The configuration file (*.hwc) is loaded (entry configuration=*.hwc).
Environment Variable Paths
Most environment variables contain path lists indicating where to search for files. A path
list is a list of directory names separated by semicolons following the syntax below:
PathList = DirSpec {";" DirSpec}.
DirSpec = ["*"] DirectoryName.
Example:
GENPATH=C:\INSTALL\LIB;D:\PROJECTS\TESTS;/usr/local/hiwave/
lib;/home/me/my_project
If a directory name is preceded by an asterisk ("*"), the programs recursively search the
directory tree for a file, not just the given directory. Directories are searched in the order
they appear in the path list.
Example:
GENPATH=.\;*S;O
NOTE Some DOS environment variables (like GENPATH, LIBPATH, etc.) are used.
We strongly recommend working with WinEdit and setting the environment by means of a
DEFAULT.ENV file in your project directory. This project directory can be set in
WinEdit's Project Configure menu command. This way, you can have different projects in
different directories, each with its own environment.
![](asset-351.png)
Debugger Engine Environment Variables
Local Configuration File (usually project.ini)
849
Microcontrollers Debugger Manual
NOTE When using WinEdit, do not set the system environment variable
Defaultdir. If you do and this variable does not contain the project
directory given in WinEdit’s project configuration, files might not be put
where you expect them.
Line Continuation
It is possible to specify an environment variable in an environment file (default.env/
.hidefaults) over multiple lines by using the line continuation character ‘\’:
Example:
OPTIONS=\
-W2 \
-Wpd
This is the same as:
OPTIONS=-W2 -Wpd
Be careful when using the line continuation character with paths. For example:
GENPATH=.\
TEXTFILE=.\txt
Results in:
GENPATH=.TEXTFILE=.\txt
To avoid such problems, use a semicolon’;’ at the end of a path, if there is a ‘\’ at the end:
GENPATH=.\;
TEXTFILE=.\txt

Legacy PEDebug Target
Interface
The PEDebug Target Interface has become “Legacy” and has been replaced by specific
Debugger Connections. The Target Interface term has been replaced by the term
Connection.
New P&E Connections for HC(S)08
For the HC08 CPU, the following P&E connections have been created to replace the
former Target Interfaces:
• Full Chip Simulation Connection
• Mon08 Interface Connection
• ICS Mon08 Interface Connection
• P&E Multilink/Cyclone Pro Connection
• ICS P&E Multilink/Cyclone Pro Connection
For the HCS08 CPU, the P&E following connections have been created:
• Full Chip Simulation Connection
• P&E Multilink/Cyclone Pro Connection
Refer to specific manual chapter to get further details about each connection.
“Revert to Full Chip Simulator” Feature
Removed
These new connections NO LONGER revert to the default FCS when the hardware cannot
be contacted. It is now necessary to open the Set Connection dialog box and to choose the
FCS if that is the connection you want. The FCS is now a Connection with the same
priority as any other connection.

Connection Selection or Change Always
Available within IDE
The CW08v5.x IDE featured a new menu option in the Project menu. The Change MCU/
Connection option opens the Device and Connection dialog box, where you can change
the currently selected project connection.
Automatic Upgrade Path for Projects
