2.0 GUIDELINES FOR GETTING
STARTED WITH 16-BIT DIGITAL
SIGNAL CONTROLLERS AND
MICROCONTROLLERS
2.1 Basic Connection Requirements
Getting started with the 16-bit DSCs and microcontrollers
requires attention to a minimal set of device pin
connections before proceeding with development. The
following is a list of pin names, which must always be
connected:
• All VDD and VSS pins (see Section 2.2
“Decoupling Capacitors”)
• All AVDD and AVSS pins (regardless if ADC module
is not used) (see Section 2.2 “Decoupling
Capacitors”)
•V
CAP (see Section 2.3 “CPU Logic Filter
Capacitor Connection (VCAP)”)
•MCLR
pin (see Section 2.4 “Master Clear (MCLR)
Pin”)
• PGECx/PGEDx pins used for In-Circuit Serial
Programming™ (ICSP™) and debugging purposes
(see Section 2.5 “ICSP Pins”)
• OSC1 and OSC2 pins when external oscillator
source is used (see Section 2.6 “External
Oscillator Pins”)
Additionally, the following pins may be required:
•V
USB3V3 pin is used when utilizing the USB
module. If the USB module is not used, VUSB3V3
must be connected to VDD.
•V
REF+/VREF- pin is used when external voltage
reference for ADC module is implemented
2.2 Decoupling Capacitors
The use of decoupling capacitors on every pair of
power supply pins, such as VDD, VSS, VUSB3V3,
AVDD and AVSS is required.
Consider the following criteria when using decoupling
capacitors:
•Value and type of capacitor: Recommendation of
0.1 µF (100 nF), 10-20V. This capacitor should be a
low-ESR and have resonance frequency in the
range of 20 MHz and higher. It is recommended to
use ceramic capacitors.
•Placement on the printed circuit board: The
decoupling capacitors should be placed as close to
the pins as possible. It is recommended to place the
capacitors on the same side of the board as the
device. If space is constricted, the capacitor can be
placed on another layer on the PCB using a via;
however, ensure that the trace length from the pin to
the capacitor is within one-quarter inch (6 mm) in
length.
•Handling high frequency noise: If the board is
experiencing high frequency noise, above tens of
MHz, add a second ceramic-type capacitor in
parallel to the above described decoupling capaci-
tor. The value of the second capacitor can be in the
range of 0.01 µF to 0.001 µF. Place this second
capacitor next to the primary decoupling capacitor.
In high-speed circuit designs, consider implement-
ing a decade pair of capacitances as close to the
power and ground pins as possible. For example,
0.1 µF in parallel with 0.001 µF.
•Maximizing performance: On the board layout
from the power supply circuit, run the power and
return traces to the decoupling capacitors first, and
then to the device pins. This ensures that the
decoupling capacitors are first in the power chain.
Equally important is to keep the trace length
between the capacitor and the power pins to a
minimum, thereby reducing PCB track inductance.
Note 1: This data sheet summarizes
the features of the
dsPIC33EPXXX(GP/MC/MU)806/810/814
and PIC24EPXXX(GP/GU)810/814 fami-
lies of devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to the related section of the
“dsPIC33E/PIC24E Family Reference
Manual”, which is available from the
Microchip web site (www.microchip.com)
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
Note: The AVDD and AVSS pins must be
connected independent of the ADC
voltage reference source. The voltage
difference between AVDD and VDD cannot
exceed 300 mV at any time during
operation or start-up.

FIGURE 2-1: RECOMMENDED
MINIMUM CONNECTION
2.2.1 TANK CAPACITORS
On boards with power traces running longer than six
inches in length, it is suggested to use a tank capacitor
for integrated circuits including DSCs to supply a local
power source. The value of the tank capacitor should
be determined based on the trace resistance that con-
nects the power supply source to the device and the
maximum current drawn by the device in the applica-
tion. In other words, select the tank capacitor so that it
meets the acceptable voltage sag at the device. Typical
values range from 4.7 µF to 47 µF.
2.3 CPU Logic Filter Capacitor
Connection (VCAP)
A low-ESR (< 1 Ohms) capacitor is required on the
VCAP pin, which is used to stabilize the voltage
regulator output voltage. The VCAP pin must not be
connected to VDD and must have a capacitor greater
than 4.7 µF (10 µF is recommended), 16V connected
to ground. The type can be ceramic or tantalum. See
Section 32.0 “Electrical Characteristics” for
additional information.
The placement of this capacitor should be close to the
VCAP. It is recommended that the trace length not
exceeds one-quarter inch (6 mm). See Section 29.2
“On-Chip Voltage Regulator” for details.
2.4 Master Clear (MCLR) Pin
The MCLR pin provides two specific device
functions:
• Device Reset
• Device Programming and Debugging
During device programming and debugging, the
resistance and capacitance that can be added to the
pin must be considered. Device programmers and
debuggers drive the MCLR pin. Consequently,
specific voltage levels (VIH and VIL) and fast signal
transitions must not be adversely affected. Therefore,
specific values of R and C will need to be adjusted
based on the application and PCB requirements.
For example, as shown in Figure 2-2, it is
recommended that the capacitor C, be isolated from
the MCLR pin during programming and debugging
operations.
Place the components as shown in Figure 2-2 within
one-quarter inch (6 mm) from the MCLR pin.

2: As an option, instead of a hard-wired connection, an
inductor (L1) can be substituted between VDD and
AVDD to improve ADC noise rejection. The inductor
impedance should be less than 1 and the inductor
capacity greater than 10 mA.

2.5 ICSP Pins
The PGECx and PGEDx pins are used for ICSP and
debugging purposes. It is recommended to keep the
trace length between the ICSP connector and the ICSP
pins on the device as short as possible. If the ICSP con-
nector is expected to experience an ESD event, a
series resistor is recommended, with the value in the
range of a few tens of Ohms, not to exceed 100 Ohms.
Pull-up resistors, series diodes and capacitors on the
PGECx and PGEDx pins are not recommended as they
will interfere with the programmer/debugger communi-
cations to the device. If such discrete components are
an application requirement, they should be removed
from the circuit during programming and debugging.
Alternatively, refer to the AC/DC characteristics and
timing requirements information in the respective
device Flash programming specification for information
on capacitive loading limits and pin input voltage high
(VIH) and input low (VIL) requirements.
Ensure that the “Communication Channel Select” (i.e.,
PGECx/PGEDx pins) programmed into the device
matches the physical connections for the ICSP to
MPLAB® PICkit™ 3, MPLAB ICD 3, or MPLAB REAL
ICE™.
For more information on MPLAB ICD 3 and MPLAB
REAL ICE connection requirements, refer to the
following documents that are available on the
Microchip web site.
•“Using MPLAB® ICD 3” (poster) DS51765
•“MPLAB® ICD 3 Design Advisory” DS51764
•“MPLAB® REAL ICE™ In-Circuit Emulator User’s
Guide” DS51616
•“Using MPLAB® REAL ICE™ In-Circuit Emulator”
(poster) DS51749
2.6 External Oscillator Pins
Many DSCs have options for at least two oscillators: a
high-frequency primary oscillator and a low-frequency
secondary oscillator. For details, see Section 9.0
“Oscillator Configuration” for details.
The oscillator circuit should be placed on the same
side of the board as the device. Also, place the
oscillator circuit close to the respective oscillator pins,
not exceeding one-half inch (12 mm) distance
between them. The load capacitors should be placed
next to the oscillator itself, on the same side of the
board. Use a grounded copper pour around the
oscillator circuit to isolate them from surrounding
circuits. The grounded copper pour should be routed
directly to the MCU ground. Do not run any signal
traces or power traces inside the ground pour. Also, if
using a two-sided board, avoid any traces on the
other side of the board where the crystal is placed. A
suggested layout is shown in Figure 2-3.
FIGURE 2-3: SUGGESTED PLACEMENT
OF THE OSCILLATOR
CIRCUIT
2.7 Oscillator Value Conditions on
Device Start-up
If the PLL of the target device is enabled and
configured for the device start-up oscillator, the
maximum oscillator source frequency must be limited
to 3 MHz < FIN < 5.5 MHz to comply with device PLL
start-up conditions. This means that if the external
oscillator frequency is outside this range, the
application must start-up in the FRC mode first. The
default PLL settings after a POR with an oscillator
frequency outside this range will violate the device
operating speed.
Once the device powers up, the application firmware
can initialize the PLL SFRs, CLKDIV and PLLDBF to a
suitable value, and then perform a clock switch to the
Oscillator + PLL clock source. Note that clock switching
must be enabled in the device Configuration Word.
2.8 Unused I/Os
Unused I/O pins should be configured as outputs and
driven to a logic-low state.
Alternatively, connect a 1k to 10k resistor between VSS
and unused pins and drive the output to logic low.

3.0 CPU
The CPU has a 16-bit (data) modified Harvard
architecture with an enhanced instruction set, including
significant support for digital signal processing. The
CPU has a 24-bit instruction word, with a variable
length opcode field. The Program Counter (PC) is
24 bits wide and addresses up to 4M x 24 bits of user
program memory space.
An instruction prefetch mechanism helps maintain
throughput and provides predictable execution. Most
instructions execute in a single-cycle effective execu-
tion rate, with the exception of instructions that change
the program flow, the double-word move (MOV.D)
instruction, PSV accesses and the table instructions.
Overhead free program loop constructs are supported
using the DO and REPEAT instructions, both of which
are interruptible at any point.
3.1 Registers
Devices have sixteen 16-bit working registers in the
programmer’s model. Each of the working registers
can act as a Data, Address or Address Offset register.
The 16th working register (W15) operates as a Soft-
ware Stack Pointer for interrupts and calls. The working
registers, W0 through W3, and selected bits from the
STATUS register, have shadow registers for fast
context saves and restores using a single POP.S or
PUSH.S instruction.
3.2 Instruction Set
The dsPIC33EPXXXMU806/810/814 instruction set
has two classes of instructions: the MCU class of
instructions and the DSP class of instructions. The
PIC24EPXXX(GP/GU)810/814 instruction set has the
MCU class of instructions and does not support DSP
instructions. These two instruction classes are seam-
lessly integrated into the architecture and execute from
a single execution unit. The instruction set includes
many addressing modes and was designed for
optimum C compiler efficiency.
3.3 Data Space Addressing
The Base Data Space can be addressed as 32K words
or 64 Kbytes and is split into two blocks, referred to as
X and Y data memory. Each memory block has its own
independent Address Generation Unit (AGU). The
MCU class of instructions operate solely through the X
memory AGU, which accesses the entire memory map
as one linear data space. On dsPIC33EPXXX(GP/MC/
MU)806/810/814 devices, certain DSP instructions
operate through the X and Y AGUs to support dual
operand reads, which splits the data address space
into two parts. The X and Y data space boundary is
device-specific.
The upper 32 Kbytes of the data space memory map
can optionally be mapped into Program Space at any
16K program word boundary. The program-to-data
space mapping feature, known as Program Space
Visibility (PSV), lets any instruction access Program
Space as if it were data space. Moreover, the Base
Data Space address is used in conjunction with a read
or write page register (DSRPAG or DSWPAG) to form
an Extended Data Space (EDS) address. The EDS can
be addressed as 8M words or 16 Mbytes. Refer to
Section 3. “Data Memory” (DS70595) and Section 4.
“Program Memory” (DS70613) in the “dsPIC33E/
PIC24E Family Reference Manual” for more details on
EDS, PSV and table accesses.
On dsPIC33EPXXX(GP/MC/MU)806/810/814 devices,
overhead-free circular buffers (Modulo Addressing) are
supported in both X and Y address spaces. The
Modulo Addressing removes the software boundary
checking overhead for DSP algorithms. The X AGU
circular addressing can be used with any of the MCU
class of instructions. The X AGU also supports Bit-
Reversed Addressing to greatly simplify input or output
data reordering for radix-2 FFT algorithms.
PIC24EPXXX(GP/GU)810/814 devices do not support
Modulo and Bit-Reversed Addressing.
3.4 Addressing Modes
The CPU supports these addressing modes:
• Inherent (no operand)
• Relative
•Literal
• Memory Direct
• Register Direct
• Register Indirect
Each instruction is associated with a predefined
addressing mode group, depending upon its functional
requirements. As many as six addressing modes are
supported for each instruction.

3.5 Programmer’s Model
The programmer’s model is shown in Figure 3-2. All
registers in the programmer’s model are memory
mapped and can be manipulated directly by
instructions. Table 3-1 lists a description of each
register.
In addition to the registers contained in the
programmer’s model, all devices in this family
contain control registers for interrupts, while
the dsPIC33EPXXX(GP/MC/MU)806/810/814 devices
contain control registers for Modulo and Bit-reversed
Addressing. These registers are described in
subsequent sections of this document.
All registers associated with the programmer’s model
are memory mapped, as shown in Table 4-1.

3.8 Arithmetic Logic Unit (ALU)
The ALU is 16 bits wide and is capable of addition,
subtraction, bit shifts and logic operations. Unless
otherwise mentioned, arithmetic operations are two’s
complement in nature. Depending on the operation, the
ALU can affect the values of the Carry (C), Zero (Z),
Negative (N), Overflow (OV) and Digit Carry (DC)
Status bits in the SR register. The C and DC Status bits
operate as Borrow and Digit Borrow bits, respectively,
for subtraction operations.
The ALU can perform 8-bit or 16-bit operations,
depending on the mode of the instruction that is used.
Data for the ALU operation can come from the W
register array or data memory, depending on the
addressing mode of the instruction. Likewise, output
data from the ALU can be written to the W register array
or a data memory location.
Refer to the “16-bit MCU and DSC Programmer’s
Reference Manual” (DS70157) for information on the
SR bits affected by each instruction.
The core CPU incorporates hardware support for both
multiplication and division. This includes a dedicated
hardware multiplier and support hardware for 16-bit
divisor division.
3.8.1 MULTIPLIER
Using the high-speed 17-bit x 17-bit multiplier, the ALU
supports unsigned, signed, or mixed-sign operation in
several MCU multiplication modes:
• 16-bit x 16-bit signed
• 16-bit x 16-bit unsigned
• 16-bit signed x 5-bit (literal) unsigned
• 16-bit signed x 16-bit unsigned
• 16-bit unsigned x 5-bit (literal) unsigned
• 16-bit unsigned x 16-bit signed
• 8-bit unsigned x 8-bit unsigned
3.8.2 DIVIDER
The divide block supports 32-bit/16-bit and 16-bit/16-bit
signed and unsigned integer divide operations with the
following data sizes:
1. 32-bit signed/16-bit signed divide
2. 32-bit unsigned/16-bit unsigned divide
3. 16-bit signed/16-bit signed divide
4. 16-bit unsigned/16-bit unsigned divide
The quotient for all divide instructions ends up in W0
and the remainder in W1. The 16-bit signed and
unsigned DIV instructions can specify any W register
for both the 16-bit divisor (Wn) and any W register
(aligned) pair (W(m + 1):Wm) for the 32-bit dividend.
The divide algorithm takes one cycle per bit of divisor,
so both 32-bit/16-bit and 16-bit/16-bit instructions take
the same number of cycles to execute.
3.9 DSP Engine (dsPIC33EPXXX(GP/
MC/MU)806/810/814 Devices Only)
The DSP engine consists of a high-speed 17-bit x
17-bit multiplier, a 40-bit barrel shifter and a 40-bit
adder/subtracter (with two target accumulators, round
and saturation logic).
The DSP engine can also perform inherent accumula-
tor-to-accumulator operations that require no additional
data. These instructions are: ADD, SUB and NEG.
The DSP engine has options selected through bits in
the CPU Core Control register (CORCON), as listed
below:
• Fractional or integer DSP multiply (IF)
• Signed, unsigned or mixed-sign DSP multiply (US)
• Conventional or convergent rounding (RND)
• Automatic saturation on/off for ACCA (SATA)
• Automatic saturation on/off for ACCB (SATB)
• Automatic saturation on/off for writes to data
memory (SATDW)
• Accumulator Saturation mode selection
(ACCSAT)

4.0 MEMORY ORGANIZATION
The device architecture features separate program and
data memory spaces and buses. This architecture also
allows the direct access of program memory from the
data space during code execution.
4.1 Program Address Space
The device program address memory space is 4M
instructions. The space is addressable by a 24-bit
value derived either from the 23-bit PC during program
execution, or from table operation or data space
remapping as described in Section 4.8 “Interfacing
Program and Data Memory Spaces”.
User application access to the program memory space
is restricted to the lower half of the address range
(0x000000 to 0x7FFFFF). The exception is the use of
TBLRD/TBLWT operations, which use TBLPAG<7> to
permit access to the Configuration bits and Device ID
sections of the configuration memory space.
The device program memory map is shown in
Figure 4-1.

4.1.1 PROGRAM MEMORY
ORGANIZATION
The program memory space is organized in word-
addressable blocks. Although it is treated as 24 bits
wide, it is more appropriate to think of each address of
the program memory as a lower and upper word, with
the upper byte of the upper word being unimplemented.
The lower word always has an even address, while the
upper word has an odd address (Figure 4-2).
Program memory addresses are always word-aligned
on the lower word and addresses are incremented or
decremented by two during code execution. This
arrangement provides compatibility with data memory
space addressing and makes data in the program
memory space accessible.
4.1.2 INTERRUPT AND TRAP VECTORS
All devices reserve the addresses between 0x00000
and 0x000200 for hard-coded program execution vec-
tors. A hardware Reset vector is provided to redirect
code execution from the default value of the PC on
device Reset to the actual start of code. A GOTO
instruction is programmed by the user application at
address 0x000000 of the primary Flash memory or at
address 0x7FFFFC of the auxiliary Flash memory, with
the actual address for the start of code at address
0x000002 of the primary Flash memory or at address
0x7FFFFE of the auxiliary Flash memory. Reset Target
Vector Select bit (RSTPRI) in the FPOR Configuration
register controls whether primary or auxiliary Flash
Reset location is used.
A more detailed discussion of the interrupt vector
tables is provided in Section 7.1 “Interrupt Vector
Table”.

4.2 Data Address Space
The CPU has a separate 16-bit wide data memory
space. The data space is accessed using separate
Address Generation Units (AGUs) for read and write
operations. The data memory maps are shown in
Figure 4-3, Figure 4-4, Figure 4-5 and Figure 4-6.
All Effective Addresses (EAs) in the data memory space
are 16 bits wide and point to bytes within the data space.
This arrangement gives a Base Data Space address
range of 64 Kbytes or 32K words.
The Base Data Space address is used in conjunction
with a Read or Write Page register (DSRPAG or
DSWPAG) to form an Extended Data Space, which has
a total address range of 16 MBytes.
dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 devices implement up
to 56 Kbytes of data memory. If an EA point to a loca-
tion outside of this area, an all-zero word or byte is
returned.
4.2.1 DATA SPACE WIDTH
The data memory space is organized in byte-
addressable, 16-bit wide blocks. Data is aligned in
data memory and registers as 16-bit words, but all data
space EAs resolve to bytes. The Least Significant
Bytes (LSBs) of each word have even addresses, while
the Most Significant Bytes (MSBs) have odd
addresses.
4.2.2 DATA MEMORY ORGANIZATION
AND ALIGNMENT
To maintain backward compatibility with PIC® MCU
devices and improve data space memory usage
efficiency, the device instruction set supports both word
and byte operations. As a consequence of byte
accessibility, all Effective Address calculations are
internally scaled to step through word-aligned memory.
For example, the core recognizes that Post-Modified
Register Indirect Addressing mode [Ws++] results in a
value of Ws + 1 for byte operations and Ws + 2 for word
operations.
A data byte read, reads the complete word that
contains the byte, using the LSb of any EA to determine
which byte to select. The selected byte is placed onto
the LSB of the data path. That is, data memory and
registers are organized as two parallel byte-wide
entities with shared (word) address decode but
separate write lines. Data byte writes only write to the
corresponding side of the array or register that matches
the byte address.
All word accesses must be aligned to an even address.
Misaligned word data fetches are not supported, so
care must be taken when mixing byte and word
operations, or translating from 8-bit MCU code. If a
misaligned read or write is attempted, an address error
trap is generated. If the error occurred on a read, the
instruction underway is completed. If the error occurred
on a write, the instruction is executed but the write does
not occur. In either case, a trap is then executed,
allowing the system and/or user application to examine
the machine state prior to execution of the address
Fault.
All byte loads into any W register are loaded into the
LSB. The MSB is not modified.
A Sign-Extend instruction (SE) is provided to allow user
applications to translate 8-bit signed data to 16-bit
signed values. Alternatively, for 16-bit unsigned data,
user applications can clear the MSB of any W register
by executing a Zero-Extend (ZE) instruction on the
appropriate address.
4.2.3 SFR SPACE
The first 4 Kbytes of the Near Data Space, from 0x0000
to 0x0FFF, is primarily occupied by Special Function
Registers (SFRs). These are used by the core and
peripheral modules for controlling the operation of the
device.
SFRs are distributed among the modules that they
control and are generally grouped together by module.
Much of the SFR space contains unused addresses;
these are read as ‘0’.
4.2.4 NEAR DATA SPACE
The 8-Kbyte area between 0x0000 and 0x1FFF is
referred to as the Near Data Space. Locations in this
space are directly addressable through a 13-bit abso-
lute address field within all memory direct instructions.
Additionally, the whole data space is addressable using
MOV instructions, which support Memory Direct
Addressing mode with a 16-bit address field, or by
using Indirect Addressing mode using a working
register as an Address Pointer.
Note: The actual set of peripheral features and
interrupts varies by the device. Refer to
the corresponding device tables and
pinout diagrams for device-specific
information.

DS70616G-page 54 2009-2012 Microchip Technology Inc.
4.2.5 X AND Y DATA SPACES
The dsPIC33EPXXX(GP/MC/MU)806/810/814 core
has two data spaces, X and Y. These data spaces can
be considered either separate (for some DSP
instructions), or as one unified linear address range (for
MCU instructions). The data spaces are accessed
using two Address Generation Units (AGUs) and
separate data paths. This feature allows certain
instructions to concurrently fetch two words from RAM,
thereby enabling efficient execution of DSP algorithms
such as Finite Impulse Response (FIR) filtering and
Fast Fourier Transform (FFT).
The PIC24EPXXX(GP/GU)806/810/814 devices do not
have a Y data space and a Y AGU. For these devices,
the entire data space is treated as X data space.
The X data space is used by all instructions and
supports all addressing modes. X data space has
separate read and write data buses. The X read data
bus is the read data path for all instructions that view
data space as combined X and Y address space. It is
also the X data prefetch path for the dual operand DSP
instructions (MAC class).
The Y data space is used in concert with the X data
space by the MAC class of instructions (CLR, ED,
EDAC, MAC, MOVSAC, MPY, MPY.N and MSC) to provide
two concurrent data read paths.
Both the X and Y data spaces support Modulo
Addressing mode for all instructions, subject to
addressing mode restrictions. Bit-Reversed
Addressing mode is only supported for writes to X data
space. Modulo Addressing and Bit-Reversed
Addressing are not present in PIC24EPXXX(GP/
GU)806/810/814 devices.
All data memory writes, including in DSP instructions,
view data space as combined X and Y address space.
The boundary between the X and Y data spaces is
device-dependent and is not user-programmable.
4.2.6 DMA RAM
Each dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 device contains
4 Kbytes of dual ported DMA RAM located at the end
of Y data RAM and is part of Y data space. Memory
locations in the DMA RAM space are accessible simul-
taneously by the CPU and the DMA Controller module.
DMA RAM is utilized by the DMA controller to store
data to be transferred to various peripherals using
DMA, as well as data transferred from various periph-
erals using DMA. The DMA RAM can be accessed by
the DMA controller without having to steal cycles from
the CPU.
When the CPU and the DMA controller attempt to
concurrently write to the same DMA RAM location, the
hardware ensures that the CPU is given precedence in
accessing the DMA RAM location. Therefore, the DMA
RAM provides a reliable means of transferring DMA
data without ever having to stall the CPU.

4.4.1 PAGED MEMORY SCHEME
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 architecture extends
the available data space through a paging scheme,
which allows the available data space to be accessed
using MOV instructions in a linear fashion for pre- and
post-modified Effective Addresses (EA). The upper half
of Base Data Space address is used in conjunction with
the Data Space Page registers, the 10-Bit Read Page
register (DSRPAG) or the 9-Bit Write Page register
(DSWPAG), to form an Extended Data Space (EDS)
address or Program Space Visibility (PSV) address.
The Data Space Page registers are located in the SFR
space.
Construction of the EDS address is shown in Figure 4-1.
When DSRPAG<9> = 0 and the base address bit,
EA<15> = 1, DSRPAG<8:0> is concatenated onto
EA<14:0> to form the 24-bit EDS read address.
Similarly, when the base address bit, EA<15> = 1,
DSWPAG<8:0> is concatenated onto EA<14:0> to form
the 24-bit EDS write address.

EXAMPLE 4-2: EXTENDED DATA SPACE (EDS) WRITE ADDRESS GENERATION
The paged memory scheme provides access to
multiple 32-Kbyte windows in the EDS and PSV
memory. The Data Space Page registers DSxPAG, in
combination with the upper half of data space address
can provide up to 16 Mbytes of additional address
space in the EDS and 12 Mbytes (DSRPAG only) of
PSV address space. The paged data memory space is
shown in Example 4-3.
The Program Space (PS) can be accessed with
DSRPAG of 0x200 or greater. Only reads from PS are
supported using the DSRPAG. Writes to PS are not
supported, so DSWPAG is dedicated to DS, including
EDS, only. The data space and EDS can be read from
and written to using DSRPAG and DSWPAG,
respectively.

Allocating different Page registers for read and write
access allows the architecture to support data
movement between different pages in data memory.
This is accomplished by setting the DSRPAG register
value to the page from which you want to read and
configuring the DSWPAG register to the page to which
it needs to be written. Data can also be moved from
different PSV to EDS pages, by configuring the
DSRPAG and DSWPAG registers to address PSV and
EDS space, respectively. The data can be moved
between pages by a single instruction.
When an EDS or PSV page overflow or underflow
occurs, EA<15> is cleared as a result of the register
indirect EA calculation. An overflow or underflow of the
EA in the EDS or PSV pages can occur at the page
boundaries when:
• The initial address, prior to modification,
addresses an EDS or PSV page.
• The EA calculation uses Pre- or Post-Modified
Register Indirect Addressing. However, this does
not include Register Offset Addressing.
In general, when an overflow is detected, the DSxPAG
register is incremented and the EA<15> bit is set to
keep the base address within the EDS or PSV window.
When an underflow is detected, the DSxPAG register is
decremented and the EA<15> bit is set to keep the
base address within the EDS or PSV window. This
creates a linear EDS and PSV address space, but only
when using Register Indirect Addressing modes.
Exceptions to the operation described above arise
when entering and exiting the boundaries of Page 0,
EDS and PSV spaces. Table 4 - 7 3 lists the effects of
overflow and underflow scenarios at different
boundaries.
In the following cases, when overflow or underflow
occurs, the EA<15> bit is set and the DSxPAG is not
modified; therefore, the EA will wrap to the beginning of
the current page:
• Register Indirect with Register Offset Addressing
• Modulo Addressing
• Bit-Reversed Addressing

2: An EDS access with DSxPAG = 0x000 will generate an address error trap.
3: Only reads from PS are supported using DSRPAG. An attempt to write to PS using DSWPAG will generate

4.4.2 EXTENDED X DATA SPACE
The lower half of the base address space range, between
0x0000 and 0x7FFF, is always accessible regardless of
the contents of the Data Space Page registers. It is
indirectly addressable through the register indirect
instructions. It can be regarded as being located in the
default EDS Page 0 (i.e., EDS address range of
0x000000 to 0x007FFF with the base address bit,
EA<15> = 0, for this address range). However, Page 0
cannot be accessed through the upper 32 Kbytes
(0x8000 to 0xFFFF) of Base Data Space, in combination
with DSRPAG = 0x00 or DSWPAG = 0x00.
Consequently, DSRPAG and DSWPAG are initialized to
0x001 at Reset.
The remaining pages including both EDS and PSV
pages are only accessible using the DSRPAG or
DSWPAG registers in combination with the upper
32 Kbytes, 0x8000 to 0xFFFF, of the base address,
where base address bit, EA<15> = 1.
For example, when DSRPAG = 0x01 or
DSWPAG = 0x01, accesses to the upper 32 Kbytes,
0x8000 to 0xFFFF, of the data space will map to the
EDS address range of 0x008000 to 0x00FFFF.
When DSRPAG = 0x02 or DSWPAG = 0x02,
accesses to the upper 32 Kbytes of the data space
will map to the EDS address range of 0x010000 to
0x017FFF and so on, as shown in the EDS memory
map in Figure 4-7.
For more information of the PSV page access using
Data Space Page registers refer to Section 4.5
“Program Space Visibility from Data Space” in
Section 4. “Program Memory” (DS70613) of the
“dsPIC33E/PIC24E Family Reference Manual”.

4.4.3 EDS ARBITRATION AND BUS
MASTER PRIORITY
EDS accesses from bus masters in the system are
arbitrated.
The arbiter for data memory (including EDS) arbitrates
between the CPU, the DMA, the USB module and the
ICD module. In the event of coincidental access to a
bus by the bus masters, the arbiter determines which
bus master access has the highest priority. The other
bus masters are suspended and processed after the
access of the bus by the bus master with the highest
priority.
By default, the CPU is Bus Master 0 (M0) with the
highest priority and the ICD is Bus Master 4 (M4) with
the lowest priority. The remaining bus masters (USB
and DMA Controllers) are allocated to M2 and M3,
respectively (M1 is reserved and cannot be used). The
user application may raise or lower the priority of the
masters to be above that of the CPU by setting the
appropriate bits in the EDS Bus Master Priority Control
(MSTRPR) register. All bus masters with raised
priorities will maintain the same priority relationship
relative to each other (i.e., M1 being highest and M3
being lowest, with M2 in between). Also, all the bus
masters with priorities below that of the CPU maintain
the same priority relationship relative to each other.
The priority schemes for bus masters with different
MSTRPR values are tabulated in Table 4-74.
This bus master priority control allows the user
application to manipulate the real-time response of the
system, either statically during initialization, or
dynamically in response to real-time events.

4.4.4 SOFTWARE STACK
The W15 register serves as a dedicated software Stack
Pointer (SP) and is automatically modified by exception
processing, subroutine calls and returns; however,
W15 can be referenced by any instruction in the same
manner as all other W registers. This simplifies
reading, writing and manipulating of the Stack Pointer
(for example, creating stack frames).
W15 is initialized to 0x1000 during all Resets. This
address ensures that the SP points to valid RAM in
all dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 devices and permits
stack availability for non-maskable trap exceptions.
These can occur before the SP is initialized by the user
software. You can reprogram the SP during
initialization to any location within data space.
The Stack Pointer always points to the first available
free word and fills the software stack working from
lower toward higher addresses. Figure 4-9 illustrates
how it pre-decrements for a stack pop (read) and
post-increments for a stack push (writes).
When the PC is pushed onto the stack, PC<15:0> is
pushed onto the first available stack word, then
PC<22:16> is pushed into the second available stack
location. For a PC push during any CALL instruction,
the MSB of the PC is zero-extended before the push,
as shown in Figure 4-9. During exception processing,
the MSB of the PC is concatenated with the lower 8 bits
of the CPU STATUS Register, SR. This allows the
contents of SRL to be preserved automatically during
interrupt processing.
FIGURE 4-9: CALL STACK FRAME
4.5 Instruction Addressing Modes
The addressing modes, shown in Table 4-75, form the
basis of the addressing modes optimized to support the
specific features of individual instructions. The
addressing modes provided in the MAC class of
instructions differ from those in the other instruction
types.
4.5.1 FILE REGISTER INSTRUCTIONS
Most file register instructions use a 13-bit address field
(f) to directly address data present in the first
8192 bytes of data memory (Near Data Space). Most
file register instructions employ a working register, W0,
which is denoted as WREG in these instructions. The
destination is typically either the same file register or
WREG (with the exception of the MUL instruction),
which writes the result to a register or register pair. The
MOV instruction allows additional flexibility and can
access the entire data space.
4.5.2 MCU INSTRUCTIONS
The three-operand MCU instructions are of the form:
Operand 3 = Operand 1 <function> Operand 2
where Operand 1 is always a working register (that is,
the addressing mode can only be Register Direct),
which is referred to as Wb. Operand 2 can be a W reg-
ister, fetched from data memory, or a 5-bit literal. The
result location can be either a W register or a data
memory location. The following addressing modes are
supported by MCU instructions:
• Register Direct
• Register Indirect
• Register Indirect Post-Modified
• Register Indirect Pre-Modified
• 5-bit or 10-bit Literal
Note: To protect against misaligned stack
accesses, W15<0> is fixed to ‘0’ by the
hardware.
Note 1: For main system Stack Pointer (W15)
coherency, W15 is never subject to
(EDS) paging and is therefore,
restricted to the address range of
0x0000 to 0xFFFF. The same applies to
W14 when used as a Stack Frame
Pointer (SFA = 1).
2: As the stack can be placed in and
across X, Y and DMA RAM spaces,
care must be exercised regarding its
use, particularly with regard to local
automatic variables in a C development
environment.
Note: Not all instructions support all of the
addressing modes given above. Individ-
ual instructions can support different
subsets of these addressing modes.

TABLE 4-75: FUNDAMENTAL ADDRESSING MODES SUPPORTED
4.5.3 MOVE AND ACCUMULATOR
INSTRUCTIONS
Move instructions (dsPIC33EPXXXMU806/810/814
and PIC24EPXXXGU810/814) and the DSP accumula-
tor class of instructions (dsPIC33EPXXXMU806/810/
814 only) provide a greater degree of addressing
flexibility than other instructions. In addition to the
addressing modes supported by most MCU
instructions, move and accumulator instructions also
support Register Indirect with Register Offset
Addressing mode, also referred to as Register Indexed
mode.
In summary, the following addressing modes are
supported by move and accumulator instructions:
• Register Direct
• Register Indirect
• Register Indirect Post-modified
• Register Indirect Pre-modified
• Register Indirect with Register Offset (Indexed)
• Register Indirect with Literal Offset
• 8-Bit Literal
• 16-Bit Literal
4.5.4 MAC INSTRUCTIONS
(dsPIC33EPXXXMU806/810/814
DEVICES ONLY)
The dual source operand DSP instructions (CLR, ED,
EDAC, MAC, MPY, MPY.N, MOVSAC and MSC), also referred
to as MAC instructions, use a simplified set of addressing
modes to allow the user application to effectively
manipulate the Data Pointers through register indirect
tables.
The two-source operand prefetch registers must be
members of the set {W8, W9, W10, W11}. For data
reads, W8 and W9 are always directed to the X RAGU,
and W10 and W11 are always directed to the Y AGU.
The Effective Addresses generated (before and after
modification) must, therefore, be valid addresses within
X data space for W8 and W9 and Y data space for W10
and W11.
In summary, the following addressing modes are
supported by the MAC class of instructions:
• Register Indirect
• Register Indirect Post-Modified by 2
• Register Indirect Post-Modified by 4
• Register Indirect Post-Modified by 6
• Register Indirect with Register Offset (Indexed)
4.5.5 OTHER INSTRUCTIONS
Besides the addressing modes outlined previously, some
instructions use literal constants of various sizes. For
example, BRA (branch) instructions use 16-bit signed
literals to specify the branch destination directly, whereas
the DISI instruction uses a 14-bit unsigned literal field. In
some instructions, such as ULNK, the source of an
operand or result is implied by the opcode itself. Certain
operations, such as NOP, do not have any operands.
Addressing Mode Description
File Register Direct The address of the file register is specified explicitly.
Register Direct The contents of a register are accessed directly.
Register Indirect The contents of Wn forms the Effective Address (EA).
Register Indirect Post-Modified The contents of Wn forms the EA. Wn is post-modified (incremented
or decremented) by a constant value.
Register Indirect Pre-Modified Wn is pre-modified (incremented or decremented) by a signed constant value
to form the EA.
Register Indirect with Register Offset
(Register Indexed)
The sum of Wn and Wb forms the EA.
Register Indirect with Literal Offset The sum of Wn and a literal forms the EA.
Note: For the MOV instructions, the addressing
mode specified in the instruction can differ
for the source and destination EA.
However, the 4-bit Wb (Register Offset)
field is shared by both source and
destination (but typically only used by
one).
Note: Not all instructions support all the
addressing modes given above. Individual
instructions may support different subsets
of these addressing modes.
Note: Register Indirect with Register Offset
Addressing mode is available only for W9
(in X space) and W11 (in Y space).

4.6 Modulo Addressing
(dsPIC33EPXXXMU806/810/814
Devices Only)
Modulo Addressing mode is a method of providing an
automated means to support circular data buffers using
hardware. The objective is to remove the need for
software to perform data address boundary checks
when executing tightly looped code, as is typical in
many DSP algorithms.
Modulo Addressing can operate in either data or
Program Space (since the Data Pointer mechanism is
essentially the same for both). One circular buffer can be
supported in each of the X (which also provides the point-
ers into Program Space) and Y data spaces. Modulo
Addressing can operate on any W Register Pointer. How-
ever, it is not advisable to use W14 or W15 for Modulo
Addressing since these two registers are used as the
Stack Frame Pointer and Stack Pointer, respectively.
In general, any particular circular buffer can be config-
ured to operate in only one direction as there are
certain restrictions on the buffer start address (for incre-
menting buffers), or end address (for decrementing
buffers), based upon the direction of the buffer.
The only exception to the usage restrictions is for
buffers that have a power-of-two length. As these
buffers satisfy the start and end address criteria, they
can operate in a bidirectional mode (that is, address
boundary checks are performed on both the lower and
upper address boundaries).
4.6.1 START AND END ADDRESS
The Modulo Addressing scheme requires that a
starting and ending address be specified and loaded
into the 16-bit Modulo Buffer Address registers:
XMODSRT, XMODEND, YMODSRT and YMODEND
(see Ta bl e 4 -1 ).
The length of a circular buffer is not directly specified. It
is determined by the difference between the
corresponding start and end addresses. The maximum
possible length of the circular buffer is 32K words
(64 Kbytes).
4.6.2 W ADDRESS REGISTER
SELECTION
The Modulo and Bit-Reversed Addressing Control
register, MODCON<15:0>, contains enable flags as well
as a W register field to specify the W Address registers.
The XWM and YWM fields select the registers that
operate with Modulo Addressing:
•If XWM = 1111, X RAGU and X WAGU Modulo
Addressing is disabled.
•If YWM = 1111, Y AGU Modulo Addressing is
disabled.
The X Address Space Pointer W register (XWM), to
which Modulo Addressing is to be applied, is stored in
MODCON<3:0> (see Table 4-1). Modulo Addressing is
enabled for X data space when XWM is set to any value
other than ‘1111’ and the XMODEN bit is set at
MODCON<15>.
The Y Address Space Pointer W register (YWM) to
which Modulo Addressing is to be applied is stored in
MODCON<7:4>. Modulo Addressing is enabled for Y
data space when YWM is set to any value other than
‘1111’ and the YMODEN bit is set at MODCON<14>.

4.6.3 MODULO ADDRESSING
APPLICABILITY
Modulo Addressing can be applied to the Effective
Address (EA) calculation associated with any W
register. Address boundaries check for addresses
equal to:
• The upper boundary addresses for incrementing
buffers
• The lower boundary addresses for decrementing
buffers
It is important to realize that the address boundaries
check for addresses less than or greater than the upper
(for incrementing buffers) and lower (for decrementing
buffers) boundary addresses (not just equal to).
Address changes can, therefore, jump beyond
boundaries and still be adjusted correctly.
4.7 Bit-Reversed Addressing
(dsPIC33EPXXXMU806/810/814
Devices Only)
Bit-Reversed Addressing mode is intended to simplify
data reordering for radix-2 FFT algorithms. It is
supported by the X AGU for data writes only.
The modifier, which can be a constant value or register
contents, is regarded as having its bit order reversed.
The address source and destination are kept in normal
order. Thus, the only operand requiring reversal is the
modifier.
4.7.1 BIT-REVERSED ADDRESSING
IMPLEMENTATION
Bit-Reversed Addressing mode is enabled in any of
these situations:
• BWMx bits (W register selection) in the MODCON
register are any value other than ‘1111’ (the stack
cannot be accessed using Bit-Reversed
Addressing)
• The BREN bit is set in the XBREV register
• The addressing mode used is Register Indirect
with Pre-Increment or Post-Increment
If the length of a bit-reversed buffer is M = 2N bytes,
the last ‘N’ bits of the data buffer start address must
be zeros.
XB<14:0> is the Bit-Reversed Address modifier, or
‘pivot point,’ which is typically a constant. In the case of
an FFT computation, its value is equal to half of the FFT
data buffer size.
When enabled, Bit-Reversed Addressing is executed
only for Register Indirect with Pre-Increment or Post-
Increment Addressing and word-sized data writes. It
does not function for any other addressing mode or for
byte-sized data and normal addresses are generated
instead. When Bit-Reversed Addressing is active, the
W Address Pointer is always added to the address
modifier (XB) and the offset associated with the
Register Indirect Addressing mode is ignored. In
addition, as word-sized data is a requirement, the LSb
of the EA is ignored (and always clear).
If Bit-Reversed Addressing has already been enabled
by setting the BREN (XBREV<15>) bit, a write to the
XBREV register should not be immediately followed by
an indirect read operation using the W register that has
been designated as the Bit-Reversed Pointer.
Note: The modulo corrected Effective Address
is written back to the register only when
Pre-Modify or Post-Modify Addressing
mode is used to compute the Effective
Address. When an address offset (such
as [W7 + W2]) is used, Modulo
Addressing correction is performed but
the contents of the register remain
unchanged.
Note: All bit-reversed EA calculations assume
word-sized data (LSb of every EA is
always clear). The XB value is scaled
accordingly to generate compatible (byte)
addresses.
Note: Modulo Addressing and Bit-Reversed
Addressing can be enabled simultaneously
using the same W register, but Bit-
Reversed Addressing operation will always
take precedence for data writes when
enabled.

4.8 Interfacing Program and Data
Memory Spaces
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 architecture uses a
24-bit wide Program Space and a 16-bit wide data
space. The architecture is also a modified Harvard
scheme, meaning that data can also be present in the
Program Space. To use this data successfully, it must
be accessed in a way that preserves the alignment of
information in both spaces.
Aside from normal execution, the
dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 architecture provides
two methods by which Program Space can be
accessed during operation:
• Using table instructions to access individual bytes
or words anywhere in the Program Space
• Remapping a portion of the Program Space into
the data space (Program Space Visibility)
Table instructions allow an application to read or write
to small areas of the program memory. This capability
makes the method ideal for accessing data tables that
need to be updated periodically. It also allows access
to all bytes of the program word. The remapping
method allows an application to access a large block of
data on a read-only basis, which is ideal for look-ups
from a large table of static data. The application can
only access the least significant word of the program
word.

4.8.1 DATA ACCESS FROM PROGRAM
MEMORY USING TABLE
INSTRUCTIONS
The TBLRDL and TBLWTL instructions offer a direct
method of reading or writing the lower word of any
address within the Program Space without going
through data space. The TBLRDH and TBLWTH
instructions are the only method to read or write the
upper 8 bits of a Program Space word as data.
The PC is incremented by two for each successive
24-bit program word. This allows program memory
addresses to directly map to data space addresses.
Program memory can thus be regarded as two 16-bit
wide word address spaces, residing side by side, each
with the same address range. TBLRDL and TBLWTL
access the space that contains the least significant
data word. TBLRDH and TBLWTH access the space that
contains the upper data byte.
Two table instructions are provided to move byte or
word-sized (16-bit) data to and from Program Space.
Both function as either byte or word operations.
•TBLRDL (Table Read Low):
- In Word mode, this instruction maps the
lower word of the Program Space
location (P<15:0>) to a data address
(D<15:0>).
- In Byte mode, either the upper or lower byte
of the lower program word is mapped to the
lower byte of a data address. The upper byte
is selected when Byte Select is ‘1’; the lower
byte is selected when it is ‘0’.
•TBLRDH (Table Read High):
- In Word mode, this instruction maps the entire
upper word of a program address (P<23:16>)
to a data address. The ‘phantom’ byte
(D<15:8>), is always ‘0’.
- In Byte mode, this instruction maps the upper
or lower byte of the program word to D<7:0>
of the data address, in the TBLRDL instruc-
tion. The data is always ‘0’ when the upper
‘phantom’ byte is selected (Byte Select = 1).
In a similar fashion, two table instructions, TBLWTH
and TBLWTL, are used to write individual bytes or
words to a Program Space address. The details of
their operation are explained in Section 5.0 “Flash
Program Memory”.
For all table operations, the area of program memory
space to be accessed is determined by the Table Page
register (TBLPAG). TBLPAG covers the entire program
memory space of the device, including user application
and configuration spaces. When TBLPAG<7> = 0, the
table page is located in the user memory space. When
TBLPAG<7> = 1, the page is located in configuration
space.

5.0 FLASH PROGRAM MEMORY
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 devices contain
internal Flash program memory for storing and
executing application code. The memory is readable,
writable and erasable during normal operation over the
entire VDD range.
Flash memory can be programmed in two ways:
• In-Circuit Serial Programming™ (ICSP™)
programming capability
• Run-Time Self-Programming (RTSP)
ICSP allows a dsPIC33EPXXX(GP/MC/MU)806/810/
814 and PIC24EPXXX(GP/GU)810/814 device to be
serially programmed while in the end application circuit.
This is done with two lines for programming clock and
programming data (one of the alternate programming
pin pairs: PGECx/PGEDx), and three other lines for
power (VDD), ground (VSS) and Master Clear (MCLR).
This allows customers to manufacture boards with
unprogrammed devices and then program the device
just before shipping the product. This also allows the
most recent firmware or a custom firmware to be
programmed.
RTSP is accomplished using TBLRD (table read) and
TBLWT (table write) instructions. With RTSP, the user
application can write program memory data either in
blocks or ‘rows’ of 128 instructions (384 bytes) at a time
or a single program memory word, and erase program
memory in blocks or ‘pages’ of 1024 instructions
(3072 bytes) at a time.
5.1 Table Instructions and Flash
Programming
Regardless of the method used, all programming of
Flash memory is done with the table read and table
write instructions. These allow direct read and write
access to the program memory space from the data
memory while the device is in normal operating mode.
The 24-bit target address in the program memory is
formed using bits<7:0> of the TBLPAG register and the
Effective Address (EA) from a W register, specified in
the table instruction, as shown in Figure 5-1.
The TBLRDL and the TBLWTL instructions are used to
read or write to bits<15:0> of program memory.
TBLRDL and TBLWTL can access program memory in
both Word and Byte modes.
The TBLRDH and TBLWTH instructions are used to read
or write to bits<23:16> of program memory. TBLRDH
and TBLWTH can also access program memory in Word
or Byte mode.

5.2 RTSP Operation
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 Flash program memory
array is organized into rows of 128 instructions or
384 bytes. RTSP allows the user application to erase a
page of memory, which consists of eight rows
(1024 instructions) at a time, and to program one row
or one word at a time. Table 32-12 lists typical erase and
programming times. The 8-row erase pages and single
row write rows are edge-aligned from the beginning of
program memory, on boundaries of 3072 bytes and
384 bytes, respectively.
The program memory implements holding buffers,
which are located in the write latch area, that can con-
tain 128 instructions of programming data. Prior to the
actual programming operation, the write data must be
loaded into the buffers sequentially. The instruction
words loaded must always be from a group of
64 boundary.
The basic sequence for RTSP programming is to set up
a Table Pointer, then do a series of TBLWT instructions
to load the buffers. Programming is performed by
setting the control bits in the NVMCON register. A total
of 128 TBLWTL and TBLWTH instructions are required
to load the instructions.
All of the table write operations are single-word writes
(two instruction cycles) because only the buffers are
written. A programming cycle is required for program-
ming each row. For more information on erasing and
programming Flash memory, refer to Section 5.
“Flash Programming” (DS70609) in the “dsPIC33E/
PIC24E Family Reference Manual”.
5.3 Programming Operations
A complete programming sequence is necessary for
programming or erasing the internal Flash in RTSP
mode. The processor stalls (waits) until the
programming operation is finished.
The programming time depends on the FRC accuracy
(see Table 32-19) and the value of the FRC Oscillator
Tuning register (see Register 9-4). Use the following
formula to calculate the minimum and maximum values
for the Row Write Time, Page Erase Time and Word
Write Cycle Time parameters (see Table 32-12).
EQUATION 5-1: PROGRAMMING TIME
For example, if the device is operating at +125°C, the
FRC accuracy will be ±5%. If the TUN<5:0> bits (see
Register 9-4) are set to ‘b111111, the minimum row
write time is equal to Equation 5-2.
EQUATION 5-2: MINIMUM ROW WRITE
TIME
The maximum row write time is equal to Equation 5-3.
EQUATION 5-3: MAXIMUM ROW WRITE
TIME
Setting the WR bit (NVMCON<15>) starts the
operation and the WR bit is automatically cleared
when the operation is finished.

5.5 Control Registers
Four SFRs are used to read and write the program
Flash memory: NVMCON, NVMKEY, NVMADRU and
NVMADR.
The NVMCON register (Register 5-1) controls which
blocks are to be erased, which memory type is to be
programmed and the start of the programming cycle.
NVMKEY (Register 5-4) is a write-only register that is
used for write protection. To start a programming or
erase sequence, the user application must
consecutively write 0x55 and 0xAA to the NVMKEY
register.
There are two NVM Address registers: NVMADRU and
NVMADR. These two registers, when concatenated,
form the 24-bit Effective Address (EA) of the selected
row or word for programming operations, or the
selected page for erase operations.
The NVMADRU register is used to hold the upper 8 bits
of the EA, while the NVMADR register is used to hold
the lower 16 bits of the EA.

6.0 RESETS The Reset module combines all Reset sources and
controls the device Master Reset Signal, SYSRST. The
following is a list of device Reset sources:
• POR: Power-on Reset
• BOR: Brown-out Reset
•MCLR: Master Clear Pin Reset
•SWR: RESET Instruction
• WDTO: Watchdog Timer Reset
• CM: Configuration Mismatch Reset
• TRAPR: Trap Conflict Reset
• IOPUWR: Illegal Condition Device Reset
- Illegal Opcode Reset
- Uninitialized W Register Reset
- Security Reset
A simplified block diagram of the Reset module is
shown in Figure 6-1.
Any active source of Reset will make the SYSRST sig-
nal active. On system Reset, some of the registers
associated with the CPU and peripherals are forced to
a known Reset state and some are unaffected.

6.2 RCON Control Register
All types of device Resets set a corresponding status
bit in the RCON register to indicate the type of Reset
(see Register 6-1).
A POR clears all the bits, except for the POR and BOR
bits (RCON<1:0>), that are set. The user application
can set or clear any bit at any time during code
execution. The RCON bits only serve as status bits.
Setting a particular Reset status bit in software does
not cause a device Reset to occur.
The RCON register also has other bits associated with
the Watchdog Timer and device power-saving states.
The function of these bits is discussed in other sections
of this manual.

Note: The status bits in the RCON register
should be cleared after they are read so
that the next RCON register value after a
device Reset is meaningful.

dsPIC33EPXXX(GP/MC/MU)806/810/814 and PIC24EPXXX(GP/GU)810/814
7.0 INTERRUPT CONTROLLER
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 interrupt controller
reduces the numerous peripheral interrupt request
signals to a single interrupt request signal to
the dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 CPU.
The interrupt controller has the following features:
• Up to eight processor exceptions and software
traps
• Eight user-selectable priority levels
• Interrupt Vector Table (IVT) with a unique vector
for each interrupt or exception source
• Fixed priority within a specified user priority level
• Fixed interrupt entry and return latencies
7.1 Interrupt Vector Table
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 Interrupt Vector Table
(IVT), shown in Figure 7-1, resides in the General
Segment of program memory, starting at location,
0x000004, and is used when executing code from the
General Segment. The IVT contains seven non-
maskable trap vectors and up to 114 sources of
interrupt. In general, each interrupt source has its own
vector. Each interrupt vector contains a 24-bit wide
address. The value programmed into each interrupt
vector location is the starting address of the associated
Interrupt Service Routine (ISR).
Interrupt vectors are prioritized in terms of their natural
priority. This priority is linked to their position in the
vector table. Lower addresses generally have a higher
natural priority. For example, the interrupt associated
with vector 0 takes priority over interrupts at any other
vector address.
7.2 Auxiliary Interrupt Vector
When code is being executed in the Auxiliary Segment,
a special single interrupt vector, located at address,
0x7FFFFA, is used for all interrupt sources and traps.
Once vectored to this single routine, the
VECNUM<7:0> bits (INTTREG<7:0>, Register 7-7)
can be examined to determine the source of the
interrupt or trap so that it can be properly processed.
7.3 Reset Sequence
A device Reset is not a true exception because the
interrupt controller is not involved in the Reset process.
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 devices clear their
registers in response to a Reset, which forces the PC
to zero. The digital signal controller then begins
program execution at location, 0x000000. A GOTO
instruction at the Reset address can redirect program
execution to the appropriate start-up routine.
Note 1: This data sheet summarizes the features
of the dsPIC33EPXXX(GP/MC/MU)806/
810/814 and PIC24EPXXX(GP/GU)810/
814 families of devices. It is not intended
to be a comprehensive reference source.
To complement the information in this
data sheet, refer to Section 6. “Inter-
rupts” (DS70600) of the “dsPIC33E/
PIC24E Family Reference Manual”,
which is available from the Microchip web
site (www.microchip.com).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
Note: Any unimplemented or unused vector
locations in the IVT should be
programmed with the address of a default
interrupt handler routine that contains a
RESET instruction.
Note: Reset locations are also located in the
Auxiliary Segment at the addresses
0x7FFFFC and 0x7FFFFE. The Reset
Target Vector Select bit, RSTPRI
(FICD<2>) controls whether the primary
(General Segment) or Auxiliary Segment
Reset location is used.

7.4 Interrupt Resources
Many useful resources related to Interrupts are pro-
vided on the main product page of the Microchip web
site for the devices listed in this data sheet. This
product page, which can be accessed using this link,
contains the latest updates and additional information.
7.4.1 KEY RESOURCES
• Section 6. “Interrupts” (DS70600) in the
“dsPIC33E/PIC24E Family Reference Manual”
• Code Samples
• Application Notes
• Software Libraries
• Webinars

7.5 Interrupt Control and Status
Registers
dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 devices implement
the following registers for the interrupt controller:
• INTCON1-INTCON4
•INTTREG
7.5.1 INTCON1 THROUGH INTCON4
Global interrupt control functions are controlled from
INTCON1, INTCON2, INTCON3 and INTCON4.
INTCON1 contains the Interrupt Nesting Disable bit
(NSTDIS) as well as the control and status flags for the
processor trap sources.
The INTCON2 register controls external interrupt
request signal behavior and software trap enable. This
register also contains the Global Interrupt Enable bit
(GIE).
INTCON3 contains the status flags for the USB, DMA
and DO stack overflow status trap sources.
The INTCON4 register contains the software
generated Hard Trap Status bit (SGHT).
7.5.2 IFSx
The IFS registers maintain all of the interrupt request
flags. Each source of interrupt has a status bit, which is
set by the respective peripherals or external signal and
is cleared via software.
7.5.3 IECx
The IEC registers maintain all of the interrupt enable
bits. These control bits are used to individually enable
interrupts from the peripherals or external signals.
7.5.4 IPCx
The IPC registers are used to set the Interrupt Priority
Level for each source of interrupt. Each user interrupt
source can be assigned to one of eight priority levels.
7.5.5 INTTREG
The INTTREG register contains the associated
interrupt vector number and the new CPU Interrupt
Priority Level, which are latched into the vector number
(VECNUM<7:0>) and Interrupt level bit (ILR<3:0>)
fields in the INTTREG register. The new Interrupt
Priority Level is the priority of the pending interrupt.
The interrupt sources are assigned to the IFSx, IECx
and IPCx registers in the same sequence as they are
listed in Tab l e 7 - 1. For example, the INT0 (External
Interrupt 0) is shown as having Vector Number 8 and a
natural order priority of 0. Thus, the INT0IF bit is found
in IFS0<0>, the INT0IE bit in IEC0<0> and the INT0IP
bits in the first position of IPC0 (IPC0<2:0>).
7.5.6 STATUS/CONTROL REGISTERS
Although these registers are not specifically part of the
interrupt control hardware, two of the CPU Control
registers contain bits that control interrupt functionality.
For more information on these registers refer to
Section 2. “CPU” (DS70359) in the “dsPIC33E/
PIC24E Family Reference Manual”.
• The CPU STATUS register, SR, contains the
IPL<2:0> bits (SR<7:5>). These bits indicate the
current CPU Interrupt Priority Level. The user
software can change the current CPU priority
level by writing to the IPL bits.
• The CORCON register contains the IPL3 bit
which, together with IPL<2:0>, also indicates the
current CPU priority level. IPL3 is a read-only bit
so that trap events cannot be masked by the user
software.
All Interrupt registers are described in Register 7-3
through Register 7-7 in the following pages.

dsPIC33EPXXX(GP/MC/MU)806/810/814 and PIC24EPXXX(GP/GU)810/814
8.0 DIRECT MEMORY ACCESS
(DMA)
The DMA controller transfers data between
peripheral data registers and data space SRAM.
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 DMA subsystem uses
dual-ported SRAM memory (DPSRAM) and register
structures that allow the DMA to operate across its
own, independent address and data buses with no
impact on CPU operation. This architecture eliminates
the need for cycle stealing, which halts the CPU when
a higher priority DMA transfer is requested. Both the
CPU and DMA controller can write and read to/from
addresses within data space without interference, such
as CPU stalls, resulting in maximized, real-time
performance. Alternatively, DMA operation and data
transfer to/from the memory and peripherals are not
impacted by CPU processing. For example, when a
Run-Time Self-Programming (RTSP) operation is
performed, the CPU does not execute any instructions
until RTSP is finished. This condition, however, does
not impact data transfer to/from memory and the
peripherals.
In addition, DMA can access entire data memory space
(SRAM and DPSRAM). The Data Memory Bus Arbiter
is utilized when either the CPU or DMA attempts to
access non-dual ported SRAM, resulting in potential
DMA or CPU stalls.
The DMA controller supports up to 15 independent
channels. Each channel can be configured for transfers
to or from selected peripherals. Some of the
peripherals supported by the DMA controller include:
• ECAN™
• Data Converter Interface (DCI)
• Analog-to-Digital Converter (ADC)
• Serial Peripheral Interface (SPI)
•UART
• Input Capture
• Output Compare
• Parallel Master Port (PMP)
Refer to Tab l e 8 -1 for a complete list of supported
peripherals.

In addition, DMA transfers can be triggered by timers
as well as external interrupts. Each DMA channel is
unidirectional. Two DMA channels must be allocated to
read and write to a peripheral. If more than one channel
receive a request to transfer data, a simple fixed priority
scheme, based on channel number, dictates which
channel completes the transfer and which channel, or
channels, are left pending. Each DMA channel moves
a block of data, after which it generates an interrupt to
the CPU to indicate that the block is available for
processing.
The DMA controller provides these functional
capabilities:
• Up to 15 DMA Channels
• Register Indirect With Post-Increment Addressing
mode
• Register Indirect Without Post-Increment
Addressing mode
• Peripheral Indirect Addressing mode (peripheral
generates destination address)
• CPU Interrupt after Half or Full Block Transfer
Complete
• Byte or Word Transfers
• Fixed Priority Channel Arbitration
• Manual (software) or Automatic (peripheral DMA
requests) Transfer Initiation
• One-Shot or Auto-Repeat Block Transfer modes
• Ping-Pong mode (automatic switch between two
DPSRAM start addresses after each block
transfer complete)
• DMA Request for Each Channel can be Selected
from Any Supported Interrupt Source
• Debug Support Features
The peripherals that can utilize DMA are listed in
Table 8-1.

8.1 DMA Resources
Many useful resources related to DMA are provided on
the main product page of the Microchip web site for the
devices listed in this data sheet. This product page,
which can be accessed using this link, contains the
latest updates and additional information.
8.1.1 KEY RESOURCES
•Section 22. “Direct Memory Access (DMA)”
(DS70348) in the “dsPIC33E/PIC24E Family
Reference Manual”
• Code Samples
• Application Notes
• Software Libraries
• Webinars
• All related “dsPIC33E/PIC24E Family Reference
Manual” Sections

8.2 DMA Control Registers
Each DMAC Channel x (where x = 0 through 14)
contains the following registers:
• 16-Bit DMA Channel Control register (DMAxCON)
• 16-Bit DMA Channel IRQ Select register
(DMAxREQ)
• 32-Bit DMA RAM Primary Start Address register
(DMAxSTA)
• 32-Bit DMA RAM Secondary Start Address
register (DMAxSTB)
• 16-Bit DMA Peripheral Address register (DMAxPAD)
• 14-Bit DMA Transfer Count register (DMAxCNT)
Additional status registers (DMAPWC, DMARQC,
DMAPPS, DMALCA and DSADR) are common to all
DMAC channels. These status registers provide infor-
mation on write and request collisions, as well as on
last address and channel access information.
The DMA Interrupt Flags (DMAxIF) are located in an
IFSx register in the interrupt controller. The
corresponding interrupt enable control bits (DMAxIE)
are located in an IECx register in the interrupt
controller, and the corresponding interrupt priority
control bits (DMAxIP) are located in an IPCx register in
the interrupt controller.

9.0 OSCILLATOR CONFIGURATION The oscillator system provides:
• Four external and internal oscillator options
• Auxiliary oscillator that provides clock source to
the USB module (if available)
• On-chip Phase-Locked Loop (PLL) to boost
internal operating frequency on select internal and
external oscillator sources
• On-the-fly clock switching between various clock
sources
• Doze mode for system power savings
• Fail-Safe Clock Monitor (FSCM) that detects clock
failure and permits safe application recovery or
shutdown
• Nonvolatile Configuration bits for clock source
selection
A simplified diagram of the oscillator system is shown
in Figure 9-1.
Note 1: This data sheet summarizes the features
of the dsPIC33EPXXX(GP/MC/MU)806/

dsPIC33EPXXX(GP/MC/MU)806/810/814 and PIC24EPXXX(GP/GU)810/814
10.0 POWER-SAVING FEATURES
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 devices provide the
ability to manage power consumption by selectively
managing clocking to the CPU and the peripherals.
In general, a lower clock frequency and a reduction
in the number of circuits being clocked constitutes
lower consumed power.
dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 devices can
manage power consumption in four ways:
• Clock frequency
• Instruction-based Sleep and Idle modes
• Software-controlled Doze mode
• Selective peripheral control in software
Combinations of these methods can be used to selec-
tively tailor an application’s power consumption while
still maintaining critical application features, such as
timing-sensitive communications.
10.1 Clock Frequency and Clock
Switching
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 devices allow a wide
range of clock frequencies to be selected under
application control. If the system clock configuration is
not locked, users can choose low-power or high-
precision oscillators by simply changing the NOSCx
bits (OSCCON<10:8>). The process of changing a
system clock during operation, as well as limitations to
the process, are discussed in more detail in
Section 9.0 “Oscillator Configuration”.
10.2 Instruction-Based Power-Saving
Modes
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 devices have two
special power-saving modes that are entered
through the execution of a special PWRSAV
instruction. Sleep mode stops clock operation and
halts all code execution. Idle mode halts the CPU
and code execution, but allows peripheral modules
to continue operation. The assembler syntax of the
PWRSAV instruction is shown in Example 10-1.
Sleep and Idle modes can be exited as a result of an
enabled interrupt, WDT time-out or a device Reset. When
the device exits these modes, it is said to wake up.
10.2.1 SLEEP MODE
The following occur in Sleep mode:
• The system clock source is shut down. If an
on-chip oscillator is used, it is turned off.
• The device current consumption is reduced to a
minimum, provided that no I/O pin is sourcing
current.
• The Fail-Safe Clock Monitor does not operate,
since the system clock source is disabled.
• The LPRC clock continues to run in Sleep mode if
the WDT is enabled.
• The WDT, if enabled, is automatically cleared
prior to entering Sleep mode.
• Some device features or peripherals can continue
to operate. This includes items such as the input
change notification on the I/O ports, or peripherals
that use an external clock input.
• Any peripheral that requires the system clock
source for its operation is disabled.
The device wakes up from Sleep mode on any of the
these events:
• Any interrupt source that is individually enabled
• Any form of device Reset
• A WDT time-out
On wake-up from Sleep mode, the processor restarts
with the same clock source that was active when Sleep
mode was entered.

Note 1: This data sheet summarizes the features
of the dsPIC33EPXXX(GP/MC/MU)806/
810/814 and PIC24EPXXX(GP/GU)810/
814 families of devices. It is not intended
to be a comprehensive reference source.

DS70616G-page 192 2009-2012 Microchip Technology Inc.
10.2.2 IDLE MODE
The following occur in Idle mode:
• The CPU stops executing instructions.
• The WDT is automatically cleared.
• The system clock source remains active. By
default, all peripheral modules continue to operate
normally from the system clock source, but can
also be selectively disabled (see Section 10.4
“Peripheral Module Disable”).
• If the WDT or FSCM is enabled, the LPRC also
remains active.
The device wakes from Idle mode on any of these
events:
• Any interrupt that is individually enabled
• Any device Reset
• A WDT time-out
On wake-up from Idle mode, the clock is reapplied to
the CPU and instruction execution will begin (2-4 clock
cycles later), starting with the instruction following the
PWRSAV instruction, or the first instruction in the ISR.
10.2.3 INTERRUPTS COINCIDENT WITH
POWER SAVE INSTRUCTIONS
Any interrupt that coincides with the execution of a
PWRSAV instruction is held off until entry into Sleep or
Idle mode has completed. The device then wakes up
from Sleep or Idle mode.
10.3 Doze Mode
The preferred strategies for reducing power
consumption are changing clock speed and invoking
one of the power-saving modes. In some
circumstances, this cannot be practical. For example, it
may be necessary for an application to maintain
uninterrupted synchronous communication, even while
it is doing nothing else. Reducing system clock speed
can introduce communication errors, while using a
power-saving mode can stop communications
completely.
Doze mode is a simple and effective alternative method
to reduce power consumption while the device is still
executing code. In this mode, the system clock
continues to operate from the same source and at the
same speed. Peripheral modules continue to be
clocked at the same speed, while the CPU clock speed
is reduced. Synchronization between the two clock
domains is maintained, allowing the peripherals to
access the SFRs while the CPU executes code at a
slower rate.
Doze mode is enabled by setting the DOZEN bit
(CLKDIV<11>). The ratio between peripheral and core
clock speed is determined by the DOZE<2:0> bits
(CLKDIV<14:12>). There are eight possible configu-
rations, from 1:1 to 1:128, with 1:1 being the default
setting.
Programs can use Doze mode to selectively reduce
power consumption in event-driven applications. This
allows clock-sensitive functions, such as synchronous
communications, to continue without interruption while
the CPU idles, waiting for something to invoke an
interrupt routine. An automatic return to full-speed CPU
operation on interrupts can be enabled by setting the
ROI bit (CLKDIV<15>). By default, interrupt events
have no effect on Doze mode operation.
For example, suppose the device is operating at
20 MIPS and the ECAN module has been configured
for 500 kbps based on this device operating speed. If
the device is placed in Doze mode with a clock
frequency ratio of 1:4, the ECAN module continues to
communicate at the required bit rate of 500 kbps, but
the CPU now starts executing instructions at a
frequency of 5 MIPS.
10.4 Peripheral Module Disable
The Peripheral Module Disable (PMD) registers
provide a method to disable a peripheral module by
stopping all clock sources supplied to that module.
When a peripheral is disabled using the appropriate
PMD control bit, the peripheral is in a minimum power
consumption state. The control and status registers
associated with the peripheral are also disabled, so
writes to those registers do not have effect and read
values are invalid.
A peripheral module is enabled only if both the
associated bit in the PMD register is cleared and the
peripheral is supported by the specific dsPIC® DSC
variant. If the peripheral is present in the device, it is
enabled in the PMD register by default.
Note: If a PMD bit is set, the corresponding
module is disabled after a delay of one
instruction cycle. Similarly, if a PMD bit is
cleared, the corresponding module is
enabled after a delay of one instruction
cycle (assuming the module control regis-
ters are already configured to enable
module operation).

11.0 I/O PORTS
All of the device pins (except VDD, VSS, MCLR and
OSC1/CLKI) are shared among the peripherals and the
parallel I/O ports. All I/O input ports feature Schmitt
Trigger inputs for improved noise immunity.
11.1 Parallel I/O (PIO) Ports
Generally, a parallel I/O port that shares a pin with a
peripheral is subservient to the peripheral. The
peripheral’s output buffer data and control signals are
provided to a pair of multiplexers. The multiplexers
select whether the peripheral or the associated port
has ownership of the output data and control signals of
the I/O pin. The logic also prevents “loop through,” in
which a port’s digital output can drive the input of a
peripheral that shares the same pin. Figure 11-1 illus-
trates how ports are shared with other peripherals and
the associated I/O pin to which they are connected.
When a peripheral is enabled and the peripheral is
actively driving an associated pin, the use of the pin as
a general purpose output pin is disabled. The I/O pin
can be read, but the output driver for the parallel port bit
is disabled. If a peripheral is enabled, but the peripheral
is not actively driving a pin, that pin can be driven by a
port.
All port pins have eight registers directly associated
with their operation as digital I/O. The Data Direction
register (TRISx) determines whether the pin is an input
or an output. If the data direction bit is a ‘1’, then the pin
is an input. All port pins are defined as inputs after a
Reset. Reads from the latch (LATx) read the latch.
Writes to the latch write the latch. Reads from the port
(PORTx) read the port pins, while writes to the port pins
write the latch.
Any bit and its associated data and control registers
that are not valid for a particular device is disabled. This
means the corresponding LATx and TRISx registers
and the port pin are read as zeros.
When a pin is shared with another peripheral or
function that is defined as an input only, it is
nevertheless regarded as a dedicated port because
there is no other competing source of outputs.

11.1.1 OPEN-DRAIN CONFIGURATION
In addition to the PORT, LAT and TRIS registers for
data control, some port pins can also be individually
configured for either digital or open-drain output. This
is controlled by the Open-Drain Control register,
ODCx, associated with each port. Setting any of the
bits configures the corresponding pin to act as an
open-drain output.
The open-drain feature allows the generation of
outputs higher than VDD (e.g., 5V on a 5V tolerant pin)
by using external pull-up resistors. The maximum
open-drain voltage allowed is the same as the
maximum VIH specification for that pin.
See the “Pin Diagrams” section for the available pins
and their functionality.
11.2 Configuring Analog and Digital
Port Pins
The ANSELx register controls the operation of the
analog port pins. The port pins that are to function as
analog inputs or outputs must have their corresponding
ANSELx and TRISx bits set. In order to use port pins for
I/O functionality with digital modules, such as Timers,
UARTs, etc., the corresponding ANSELx bit must be
cleared.
The ANSELx register has a default value of 0xFFFF;
therefore, all pins that share analog functions are
analog (not digital) by default. Refer to the Pinout I/O
Descriptions (Table 1-1 in Section 1.0 “Device
Overview”) for the complete list of analog pins.
If the TRISx bit is cleared (output) while the ANSELx bit
is set, the digital output level (VOH or VOL) is converted
by an analog peripheral, such as the ADC module or
Comparator module.
When the PORT register is read, all pins configured as
analog input channels are read as cleared (a low level).
Pins configured as digital inputs do not convert an
analog input. Analog levels on any pin defined as a
digital input (including the pins defined as Analog in
Table 1-1 in Section 1.0 “Device Overview”) can
cause the input buffer to consume current that
exceeds the device specifications.
11.2.1 I/O PORT WRITE/READ TIMING
One instruction cycle is required between a port
direction change or port write operation and a read
operation of the same port. Typically this instruction
would be an NOP, as shown in Example 11-1.
11.3 Input Change Notification
The input change notification function of the I/O ports
allows the dsPIC33EPXXX(GP/MC/MU)806/810/814
and PIC24EPXXX(GP/GU)810/814 devices to
generate interrupt requests to the processor in
response to a Change-of-State (COS) on selected input
pins. This feature can detect input Change-of-States
even in Sleep mode, when the clocks are disabled.
Every I/O port pin can be selected (enabled) for
generating an interrupt request on a Change-of-State.
Three control registers are associated with the CN
functionality of each I/O port. The CNENx registers
contain the CN interrupt enable control bits for each of
the input pins. Setting any of these bits enables a CN
interrupt for the corresponding pins.
Each I/O pin also has a weak pull-up and a weak
pull-down connected to it. The pull-ups act as a
current source or sink source connected to the pin,
and eliminate the need for external resistors when
push-button or keypad devices are connected. The
pull-ups and pull-downs are enabled separately using
the CNPUx and the CNPDx registers, which contain
the control bits for each of the pins. Setting any of
the control bits enables the weak pull-ups and/or
pull-downs for the corresponding pins.
EXAMPLE 11-1: PORT WRITE/READ

Note: Pull-ups and pull-downs on change notifi-
cation pins should always be disabled
when the port pin is configured as a digital
output.

11.4 Peripheral Pin Select
A major challenge in general purpose devices is provid-
ing the largest possible set of peripheral features while
minimizing the conflict of features on I/O pins. The chal-
lenge is even greater on low pin-count devices. In an
application where more than one peripheral needs to
be assigned to a single pin, inconvenient workarounds
in application code or a complete redesign may be the
only option.
Peripheral Pin Select configuration provides an
alternative to these choices by enabling peripheral set
selection and their placement on a wide range of I/O
pins. By increasing the pinout options available on a
particular device, users can better tailor the device to
their entire application, rather than trimming the
application to fit the device.
The Peripheral Pin Select configuration feature oper-
ates over a fixed subset of digital I/O pins. Users may
independently map the input and/or output of most dig-
ital peripherals to any one of these I/O pins. Peripheral
Pin Select is performed in software and generally does
not require the device to be reprogrammed. Hardware
safeguards are included that prevent accidental or
spurious changes to the peripheral mapping once it has
been established.
11.4.1 AVAILABLE PINS
The number of available pins is dependent on the
particular device and its pin count. Pins that support the
Peripheral Pin Select feature include the designation
“RPn” or “RPIn” in their full pin designation, where “RP”
designates a remappable function for input or output
and “RPI” designates a remappable functions for input
only, and “n” is the remappable pin number.
11.4.2 AVAILABLE PERIPHERALS
The peripherals managed by the Peripheral Pin Select
are all digital only peripherals. These include general
serial communications (UART and SPI), general pur-
pose timer clock inputs, timer-related peripherals (input
capture and output compare) and interrupt-on-change
inputs.
In comparison, some digital-only peripheral modules are
never included in the Peripheral Pin Select feature. This
is because the peripheral’s function requires special I/O
circuitry on a specific port and cannot be easily con-
nected to multiple pins. These modules include I2C and
the PWM. A similar requirement excludes all modules
with analog inputs, such as the ADC Converter.
A key difference between remappable and non-
remappable peripherals is that remappable peripherals
are not associated with a default I/O pin. The peripheral
must always be assigned to a specific I/O pin before it
can be used. In contrast, non-remappable peripherals
are always available on a default pin, assuming that the
peripheral is active and not conflicting with another
peripheral.
When a remappable peripheral is active on a given I/O
pin, it takes priority over all other digital I/O and digital
communication peripherals associated with the pin.
Priority is given regardless of the type of peripheral that
is mapped. Remappable peripherals never take priority
over any analog functions associated with the pin.
11.4.3 CONTROLLING PERIPHERAL PIN
SELECT
Peripheral Pin Select features are controlled through
two sets of SFRs: one to map peripheral inputs and one
to map outputs. Because they are separately con-
trolled, a particular peripheral’s input and output (if the
peripheral has both) can be placed on any selectable
function pin without constraint.
The association of a peripheral to a peripheral-selectable
pin is handled in two different ways, depending on
whether an input or output is being mapped.
11.4.4 INPUT MAPPING
The inputs of the Peripheral Pin Select options are
mapped on the basis of the peripheral. That is, a control
register associated with a peripheral dictates the pin it
will be mapped to. The RPINRx registers are used to
configure peripheral input mapping (see Register 11-1
through Register 11-22). Each register contains sets of
7-bit fields, with each set associated with one of the
remappable peripherals (see Table 11-1). Programming
a given peripheral’s bit field with an appropriate 7-bit
value maps the RPn/RPIn pin with the corresponding
value to that peripheral (see Table 11-2). For any given
device, the valid range of values for any bit field corre-
sponds to the maximum number of Peripheral Pin
Selections supported by the device.
For example, Figure 11-2 illustrates remappable pin
selection for the U1RX input.

Note: For input only, Peripheral Pin Select functionality
does not have priority over TRISx settings.
Therefore, when configuring RPn/RPIn pin for
input, the corresponding bit in the TRISx register
must also be configured for input (set to ‘1’).

11.4.4.1 Output Mapping
In contrast to inputs, the outputs of the Peripheral Pin
Select options are mapped on the basis of the pin. In
this case, a control register associated with a particular
pin dictates the peripheral output to be mapped. The
RPORx registers are used to control output mapping.
Like the RPINRx registers, each register contains sets
of 6 bit fields, with each set associated with one RPn
pin (see Register 11-44 through Register 11-51). The
value of the bit field corresponds to one of the periph-
erals and that peripheral’s output is mapped to the pin
(see Table 11-3 and Figure 11-3).
A null output is associated with the Output Register
Reset value of ‘0’. This is done to ensure that remap-
pable outputs remain disconnected from all output pins
by default.

11.4.4.2 Virtual Connections
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 devices support virtual
(internal) connections to the output of the comparator
modules, CMP1OUT, CMP2OUT and CMP3OUT (see
Figure 25-1 in Section 25.0 “Comparator Module”).
In addition, dsPIC33EPXXXMU806/810/814 devices
support virtual connections to the filtered QEI module
inputs, FINDX1, FHOME1, FINDX2 and FHOME2 (see
Figure 17-1 in Section 17.0 “Quadrature Encoder
Interface (QEI) Module (dsPIC33EPXXX(MC/
MU)8XX Devices Only)”.
Virtual connections provide a simple way of inter-
peripheral connection without utilizing a physical pin.
For example, by setting the FLT1R<6:0> bits of the
RPINR12 register to the value of ‘b0000001, the
output of the analog comparator, CMP1OUT, will be
connected to the PWM Fault 1 input, which allows the
analog comparator to trigger PWM Faults without the
use of an actual physical pin on the device.
Virtual connection to the QEI module allows
peripherals to be connected to the QEI digital filter
input. To utilize this filter, the QEI module must be
enabled, and its inputs must be connected to a physical
RPn/RPIn pin. Example 11-2 illustrates how the input
capture module can be connected to the QEI digital
filter.
11.4.4.3 Mapping Limitations
The control schema of the peripheral select pins is not
limited to a small range of fixed peripheral
configurations. There are no mutual or hardware
enforced lockouts between any of the peripheral
mapping SFRs. Literally any combination of peripheral
mappings across any or all of the RPn/RPIn pins is
possible. This includes both many-to-one and one-to-
many mappings of peripheral inputs and outputs to
pins. While such mappings may be technically possible
from a configuration point of view, they may not be
supportable from an electrical point of view.
EXAMPLE 11-2: CONNECTING IC1 TO HOME1 DIGITAL FILTER INPUT ON PIN 3 OF THE
dsPIC33EP512MU810 DEVICE
RPINR15 = 0x5600; /* Connect the QEI1 HOME1 input to RP86 (pin 3) */
RPINR7 = 0x009; /* Connect the IC1 input to the digital filter on the FHOME1 input */
QEI1IOC = 0x4000; /* Enable the QEI digital filter */
QEI1CON = 0x8000; /* Enable the QEI module */

11.5 I/O Helpful Tips
1. In some cases, certain pins, as defined in
Table 32-9 in Section 32.0 “Electrical Charac-
teristics” under “Injection Current”, have internal
protection diodes to VDD and VSS; the term
“Injection Current” is also referred to as “Clamp
Current”. On designated pins, with sufficient exter-
nal current-limiting precautions by the user, I/O pin
input voltages are allowed to be greater or less
than the data sheet absolute maximum ratings
with respect to the VSS and VDD supplies. Note
that when the user application forward biases
either of the high or low side internal input clamp
diodes, that the resulting current being injected
into the device that is clamped internally by the
VDD and VSS power rails, may affect the ADC
accuracy by four to six counts.
2. I/O pins that are shared with any analog input pin,
(i.e., ANx, see Tab l e 1 - 1 in Section 1.0 “Device
Overview”), are always analog pins by default
after any Reset. Consequently, configuring a pin
as an analog input pin, automatically disables the
digital input pin buffer and any attempt to read the
digital input level by reading PORTx or LATx will
always return a ‘0’, regardless of the digital logic
level on the pin. To use a pin as a digital I/O pin on
a shared analog pin (see Table 1-1 in Section 1.0
“Device Overview”), the user application needs
to configure the Analog Pin Configuration registers
in the I/O ports module (i.e., ANSELx) by setting
the appropriate bit that corresponds to that I/O port
pin to a ‘0’.
3. Most I/O pins have multiple functions. Referring to
the device pin diagrams in the data sheet, the
priorities of the functions allocated to any pins are
indicated by reading the pin name from left to right.
The left most function name takes precedence
over any function to its right in the naming conven-
tion. For example: AN16/T2CK/T7CK/RC1; this
indicates that AN16 is the highest priority in this
example and will supersede all other functions to
its right in the list. Those other functions to its right,
even if enabled, would not work as long as any
other function to its left was enabled. This rule
applies to all of the functions listed for a given pin.
Dedicated peripheral functions are always higher
priority than remappable functions. I/O pins are
always the lowest priority.
4. Each pin has an internal weak pull-up resistor and
pull-down resistor that can be configured using the
CNPUx and CNPDx registers, respectively. These
resistors eliminate the need for external resistors
in certain applications. The internal pull-up is up to
~(VDD-0.8), not VDD. This value is still above the
minimum VIH of CMOS and TTL devices.
5. When driving LEDs directly, the I/O pin can source
or sink more current than what is specified in the
VOH/IOH and VOL/IOL DC characteristic specifica-
tion. The respective IOH and IOL current rating only
applies to maintaining the corresponding output at
or above the VOH and at or below the VOL levels.
However, for LEDs, unlike digital inputs of an
externally connected device, they are not gov-
erned by the same minimum VIH/VIL levels. An I/O
pin output can safely sink or source any current
less than that listed in the absolute maximum
rating section of the data sheet. For example:
VOH = 2.4v @ IOH = -8 mA and VDD = 3.3V
The maximum output current sourced by any 8 mA
I/O pin = 12 mA.
LED source current < 12 mA is technically
permitted. Refer to the VOH/IOH graphs in
Section 32.0 “Electrical Characteristics” for
additional information.
6. The Peripheral Pin Select (PPS) pin mapping rules
are as follows:
a) Only one “output” function can be active on a
given pin at any time regardless if it is a dedi-
cated or remappable function (one pin, one
output).
b) It is possible to assign a “remappable output”
function to multiple pins and externally short or
tie them together for increased current drive.
c) If any “dedicated output” function is enabled
on a pin, it will take precedence over any
remappable “output” function.
d) If any “dedicated digital” (input or output)
function is enabled on a pin, any number of
“input” remappable functions can be mapped
to the same pin.
e) If any “dedicated analog” function(s) are
enabled on a given pin, “digital input(s)” of any
kind will all be disabled, although a single “dig-
ital output”, at the user’s cautionary discretion,
can be enabled and active as long as there is
no signal contention with an external analog
input signal. For example, it is possible for the
ADC to convert the digital output logic level, or
to toggle a digital output on a comparator or
ADC input, provided there is no external
analog input, such as for a built-in self test.
f) Any number of “input” remappable functions
can be mapped to the same pin(s) at the
same time, including any pin with a single out-
put from either a dedicated or remappable
“output”.
Note: Although it is not possible to use a digital
input pin when its analog function is
enabled, it is possible to use the digital I/O
output function, TRISx = 0x0, while the
analog function is also enabled. However,
this is not recommended, particularly if the
analog input is connected to an external
analog voltage source, which would
create signal contention between the
analog signal and the output pin driver.

dsPIC33EPXXX(GP/MC/MU)806/810/814 and PIC24EPXXX(GP/GU)810/814
g) The TRIS registers control only the digital I/O
output buffer. Any other dedicated or remap-
pable active “output” will automatically over-
ride the TRIS setting. The TRIS register does
not control the digital logic “input” buffer.
Remappable digital “inputs” do not automati-
cally override TRIS settings, which means
that the TRIS bit must be set to input for pins
with only remappable input function(s)
assigned.
h) All analog pins are enabled by default after
any Reset and the corresponding digital input
buffer on the pin is disabled. Only the Analog
Pin Select registers control the digital input
buffer, not the TRIS register. The user must
disable the analog function on a pin using the
Analog Pin Select registers in order to use any
“digital input(s)” on a corresponding pin, no
exceptions.

12.0 TIMER1
The Timer1 module is a 16-bit timer, which can serve
as the time counter for the real-time clock, or operate
as a free-running interval timer/counter.
The Timer1 module has the following unique features
over other timers:
• Can be operated from the low-power 32 kHz
crystal oscillator available on the device.
• Can be operated in Asynchronous Counter mode
from an external clock source.
• The external clock input (T1CK) can optionally be
synchronized to the internal device clock and clock
synchronization is performed after the prescaler.
The unique features of Timer1 allow it to be used for
Real-Time Clock (RTC) applications. A block diagram
of Timer1 is shown in Figure 12-1.
The Timer1 module can operate in one of the following
modes:
• Timer mode
• Gated Timer mode
• Synchronous Counter mode
• Asynchronous Counter mode
In Timer and Gated Timer modes, the input clock is
derived from the internal instruction cycle clock (FCY).
In Synchronous and Asynchronous Counter modes,
the input clock is derived from the external clock input
at the T1CK pin.
The Timer modes are determined by the following bits:
• Timer Clock Source Control bit (TCS): T1CON<1>
• Timer Synchronization Control bit (TSYNC):
T1CON<2>
• Timer Gate Control bit (TGATE): T1CON<6>
Timer control bit setting for different operating modes
are given in the Table 12-1.

13.0 TIMER2/3, TIMER4/5, TIMER6/7
AND TIMER8/9
The Timer2/3, Timer4/5, Timer6/7 and Timer8/9
modules are 32-bit timers, which can also be
configured as four independent 16-bit timers with
selectable operating modes.
As a 32-bit timer, Timer2/3, Timer4/5, Timer6/7 and
Timer8/9 operate in three modes:
• Two Independent 16-Bit Timers (e.g., Timer2 and
Timer3) with all 16-Bit Operating modes (except
Asynchronous Counter mode)
• Single 32-Bit Timer
• Single 32-Bit Synchronous Counter
They also support these features:
• Timer Gate Operation
• Selectable Prescaler Settings
• Timer Operation during Idle and Sleep modes
• Interrupt on a 32-Bit Period Register Match
• Time Base for Input Capture and Output Compare
Modules (Timer2 and Timer3 only)
• ADC1 Event Trigger (Timer2/3 only)
• ADC2 Event Trigger (Timer4/5 only)
Individually, all eight of the 16-bit timers can function as
synchronous timers or counters. They also offer the
features listed above, except for the event trigger; this
is implemented only with Timer2/3. The operating
modes and enabled features are determined by setting
the appropriate bit(s) in the T2CON, T3CON, T4CON,
T5CON, T6CON, T7CON, T8CON and T9CON
registers. T2CON, T4CON, T6CON and T8CON are
shown in generic form in Register 13-1. T3CON,
T5CON, T7CON and T9CON are shown in
Register 13-2.
For 32-bit timer/counter operation, Timer2, Timer4,
Timer6 or Timer8 is the least significant word; Timer3,
Timer5, Timer7 or Timer9 is the most significant word
of the 32-bit timers.
A block diagram for an example 32-bit timer pair is
shown Figure 13-3.
Note 1: This data sheet summarizes

2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
Note: For 32-bit operation, T3CON, T5CON,
T7CON and T9CON control bits are
ignored. Only T2CON, T4CON, T6CON
and T8CON control bits are used for setup
and control. Timer2, Timer4, Timer6 and
Timer8 clock and gate inputs are utilized
for the 32-bit timer modules, but an
interrupt is generated with the Timer3,
Timer5, Ttimer7 and Timer9 interrupt
flags.
Note: Only Timer2, 3, 4 and 5 can trigger a DMA
data transfer.

15.0 OUTPUT COMPARE The output compare module can select one of eight
available clock sources for its time base. The module
compares the value of the timer with the value of one or
two Compare registers, depending on the operating
mode selected. The state of the output pin changes
when the timer value matches the Compare register
value. The output compare module generates either a
single output pulse, or a sequence of output pulses, by
changing the state of the output pin on the compare
match events. The output compare module can also
generate interrupts on compare match events.

16.0 HIGH-SPEED PWM MODULE
(dsPIC33EPXXX(MC/MU)8XX
DEVICES ONLY)
The dsPIC33EPXXX(MC/MU)806/810/814 devices
support a dedicated Pulse-Width Modulation (PWM)
module with up to 14 outputs.
The high-speed PWM module consists of the following
major features:
• Two master time base modules with Special
Event Triggers
• PWM module input clock prescaler
• Two synchronization inputs
• Two synchronization outputs
• Up to seven PWM generators
• Two PWM outputs per generator (PWMxH and
PWMxL)
• Individual period, duty cycle and phase shift for
each PWM output
• Period, duty cycle, phase shift and dead-time
resolution of 8.32 ns
• Immediate update mode for PWM period, duty
cycle and phase shift
• Independent Fault and current-limited inputs for
each PWM
• Cycle-by-Cycle and Latched Fault modes
• PWM time-base capture upon current limit
• Seven Fault inputs and three comparator outputs
available for Faults and current limits
• Programmable ADC trigger with interrupt for each
PWM pair
• Complementary PWM outputs
• Push-Pull PWM outputs
• Redundant PWM outputs
• Edge-Aligned PWM mode
• Center-Aligned PWM mode
• Variable Phase PWM mode
• Multi-Phase PWM mode
• Fixed Off Time PWM mode
• Current-Limit PWM mode
• Current Reset PWM mode
• PWMxH and PWMxL output override control
• PWMxH and PWMxL output pin swapping
• Chopping mode (also known as Gated mode)
• Dead-time insertion
• Dead-time compensation
• Enhanced Leading-Edge Blanking (LEB)
• 8 mA PWM pin output drive
The high-speed PWM module contains up to seven
PWM generators. Each PWM generator provides two
PWM outputs: PWMxH and PWMxL. Two master time
base generators provide a synchronous signal as a
common time base to synchronize the various PWM
outputs. Each generator can operate independently or
in synchronization with either of the two master time
bases. The individual PWM outputs are available on
the output pins of the device. The input Fault signals
and current-limited signals, when enabled, can monitor
and protect the system by placing the PWM outputs
into a known “safe” state.
Each PWM can generate a trigger to the ADC module
to sample the analog signal at a specific instance dur-
ing the PWM period. In addition, the high-speed PWM
module also generates two Special Event Triggers to
the ADC module based on the two master time bases.
The high-speed PWM module can synchronize itself
with an external signal or can act as a synchronizing
source to any external device. The SYNCI1 and
SYNCI2 pins are the input pins, which can synchronize
the high-speed PWM module with an external signal.
The SYNCO1 and SYNCO2 pins are output pins that
provides a synchronous signal to an external device.
Figure 16-1 illustrates an architectural overview of the
high-speed PWM module and its interconnection with
the CPU and other peripherals.

18.0 SERIAL PERIPHERAL
INTERFACE (SPI)
The SPI module is a synchronous serial interface use-
ful for communicating with other peripheral or micro-
controller devices. These peripheral devices can be
serial EEPROMs, shift registers, display drivers, ADC
Converters, etc. The SPI module is compatible with the
Motorola® SPI and SIOP interfaces.
Four SPI modules are provided on a single device.
These modules, which are designated as SPI1, SPI2,
SPI3 and SPI4, are functionally identical with the excep-
tion that SPI2 is not remappable. The dedicated SDI2,
SDO2 and SCK2 connections provide improved perfor-
mance over SPI1, SPI3 and SPI4 (see Section 32.0
“Electrical Characteristics”). Each SPI module
includes an eight-word FIFO buffer and allows DMA bus
connections. When using the SPI module with DMA,
FIFO operation can be disabled.
The SPIx serial interface consists of four pins, as
follows:
• SDIx: Serial Data Input
• SDOx: Serial Data Output
• SCKx: Shift Clock Input or Output
• SSx/FSYNCx: Active-Low Slave Select or Frame
Synchronization I/O Pulse
The SPIx module can be configured to operate with
two, three or four pins. In 3-pin mode, SSx is not used.
In 2-pin mode, neither SDOx nor SSx is used.
Figure 18-1 illustrates the block diagram of the SPI
module in Standard and Enhanced modes.

18.1 SPI Helpful Tips
1. In Frame mode, if there is a possibility that the
master may not be initialized before the slave:
a) If FRMPOL (SPIxCON2<13>) = 1, use a
pull-down resistor on SSx.
b) If FRMPOL = 0, use a pull-up resistor on
SSx.
2. In Non-Framed 3-Wire mode, (i.e., not using
SSx from a master):
a) If CKP (SPIxCON1<6>) = 1, always place a
pull-up resistor on SSx.
b) If CKP = 0, always place a pull-down
resistor on SSx.
3. FRMEN (SPIxCON2<15>) = 1 and SSEN
(SPIxCON1<7>) = 1 are exclusive and invalid.
In Frame mode, SCKx is continuous and the
Frame Sync pulse is active on the SSx pin,
which indicates the start of a data frame.
4. In Master mode only, set the SMP bit
(SPIxCON1<9>) to a ‘1’ for the fastest SPI data
rate possible. The SMP bit can only be set at the
same time or after the MSTEN bit
(SPIxCON1<5>) is set.
To avoid invalid slave read data to the master, the
user’s master software must ensure enough time for
slave software to fill its write buffer before the user
application initiates a master write/read cycle. It is
always advisable to preload the SPIxBUF Transmit
register in advance of the next master transaction
cycle. SPIxBUF is transferred to the SPIx Shift register
and is empty once the data transmission begins.

Note: This insures that the first frame
transmission after initialization is not
shifted or corrupted.
Note: This will insure that during power-up and
initialization, the master/slave will not lose
synchronization due to an errant SCKx
transition that would cause the slave to
accumulate data shift errors, for both
transmit and receive, appearing as
corrupted data.
Note: Not all third-party devices support Frame
mode timing. Refer to the SPIx electrical

19.0 INTER-INTEGRATED
CIRCUIT™ (I2C™)
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 family of devices con-
tain two Inter-Integrated Circuit (I2C) modules: I2C1
and I2C2.
The I2C module provides complete hardware support
for both Slave and Multi-Master modes of the I2C serial
communication standard, with a 16-bit interface.
The I2C module has a 2-pin interface:
• The SCLx pin is the clock.
• The SDAx pin is the data.
The I2C module offers the following key features:
•I
2C interface supporting both Master and Slave
modes of operation.
•I
2C Slave mode supports 7 and 10-bit addressing.
•I
2C Master mode supports 7 and 10-bit addressing.
•I
2C port allows bidirectional transfers between
master and slaves.
• Serial clock synchronization for I2C port can be
used as a handshake mechanism to suspend and
resume serial transfer (SCLREL control).
•I
2C supports multi-master operation, detects bus
collision and arbitrates accordingly.
• IPMI support
• SMBus support

20.1 UARTx Helpful Tips
1. In multi-node direct-connect UARTx networks,
UARTx receive inputs react to the complemen-
tary logic level defined by the URXINV bit
(UxMODE<4>), which defines the Idle state, the
default of which is logic high (i.e., URXINV = 0).
Because remote devices do not initialize at the
same time, it is likely that one of the devices,
because the RX line is floating, will trigger a
Start bit detection and will cause the first byte
received, after the device has been initialized, to
be invalid. To avoid this situation, the user
should use a pull-up or pull-down resistor on the
RX pin depending on the value of the URXINV
bit.
a) If URXINV = 0, use a pull-up resistor on the
RX pin.
b) If URXINV = 1, use a pull-down resistor on
the RX pin.
2. The first character received on a wake-up from
Sleep mode, caused by activity on the UxRX pin
of the UARTx module, will be invalid. In Sleep
mode, peripheral clocks are disabled. By the
time the oscillator system has restarted and
stabilized from Sleep mode, the baud rate bit
sampling clock, relative to the incoming UxRX
bit timing, is no longer synchronized resulting in
the first character being invalid. This is to be
expected.

21.0 ENHANCED CAN (ECAN™)
MODULE
21.1 Overview
The Enhanced Controller Area Network (ECAN)
module is a serial interface, useful for communicat-
ing with other CAN modules or microcontroller
devices. This interface/protocol was designed to
allow communications within noisy environments.
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 devices contain two
ECAN modules.
The ECANx module is a communication controller
implementing the CAN 2.0 A/B protocol, as defined in
the BOSCH CAN Specification. The module supports
CAN 1.2, CAN 2.0A, CAN 2.0B Passive and CAN 2.0B
Active versions of the protocol. The module implemen-
tation is a full CAN system. The CAN Specification is
not covered within this data sheet. The reader can refer
to the BOSCH CAN specification for further details.
The ECANx module features are as follows:
• Implementation of the CAN Protocol, CAN 1.2,
CAN 2.0A and CAN 2.0B
• Standard and Extended Data Frames
• 0-8 Bytes Data Length
• Programmable Bit Rate up to 1 Mbit/sec
• Automatic Response to Remote Transmission
Requests
• Up to 8 Transmit Buffers with Application-Specific
Prioritization and Abort Capability (each buffer
can contain up to 8 bytes of data)
• Up to 32 Receive Buffers (each buffer can contain
up to 8 bytes of data)
• Up to 16 Full (standard/extended identifier)
Acceptance Filters
• Three Full Acceptance Filter Masks
• DeviceNet™ Addressing Support
• Programmable Wake-up Functionality with
Integrated Low-Pass Filter
• Programmable Loopback mode Supports
Self-Test Operation
• Signaling via Interrupt Capabilities for all CAN
Receiver and Transmitter Error States
• Programmable Clock Source
• Programmable Link to Input Capture Module (IC2
for the ECAN1 and ECAN2 modules) for
Time-Stamping and Network Synchronization
• Low-Power Sleep and Idle mode
The CAN bus module consists of a protocol engine and
message buffering/control. The CAN protocol engine
handles all functions for receiving and transmitting
messages on the CAN bus. Messages are transmitted
by first loading the appropriate data registers. Status
and errors can be checked by reading the appropriate
registers. Any message detected on the CAN bus is
checked for errors and then matched against filters to
see if it should be received and stored in one of the
receive registers.

21.2 Modes of Operation
The ECANx module can operate in one of several
operation modes selected by the user. These modes
include:
• Initialization mode
• Disable mode
• Normal Operation mode
• Listen Only mode
• Listen All Messages mode
• Loopback mode
Modes are requested by setting the REQOP<2:0> bits
(CxCTRL1<10:8>). Entry into a mode is Acknowledged
by monitoring the OPMODE<2:0> bits (CxCTRL1<7:5>).
The module does not change the mode and the
OPMODE bits until a change in mode is acceptable,
generally during bus Idle time, which is defined as at least
11 consecutive recessive bits.

22.0 USB ON-THE-GO (OTG)
MODULE (dsPIC33EPXXXMU8XX
AND PIC24EPGU8XX DEVICES
ONLY)
22.1 Overview
The Universal Serial Bus (USB) On-The-Go (OTG)
module includes the following features:
• USB Full-Speed Support for Host and Device
• Low-Speed Host Support
• USB On-The-Go Support
• Integrated Signaling Resistors
• Integrated Analog Comparators for VBUS
Monitoring
• Integrated USB Transceiver
• Hardware Performs Transaction Handshaking
• Endpoint Buffering Anywhere in System RAM
• Integrated DMA Controller to Access System
RAM
• Support for all four transfer types:
- Control
- Interrupt
-Bulk Data
- Isochronous
• Queueing of up to Four Endpoint Transfers
without Servicing
• USB 5V Charge Pump Controller
The USB module contains the analog and digital
components to provide a USB 2.0 full-speed and low-
speed embedded host, full-speed device or OTG
implementation with a minimum of external
components.
The USB module consists of the clock generator, the
USB voltage comparators, the transceiver, the Serial
Interface Engine (SIE), pull-up and pull-down resistors,
and the register interface. Figure 22-1 illustrates the
block diagram of the USB OTG module.
The device auxiliary clock generator provides the
48 MHz clock required for USB communication. The
voltage comparators monitor the voltage on the VBUS
pin to determine the state of the bus. The transceiver
provides the analog translation between the USB bus
and the digital logic. The SIE is a state machine that
transfers data to and from the endpoint buffers and
generates the protocol for data transfers. The
integrated pull-up and pull-down resistors eliminate the
need for external signaling components. The register
interface allows the CPU to configure and
communicate with the module.
22.2 Clearing USB OTG Interrupts
Unlike device level interrupts, the USB OTG interrupt
status flags are not freely writable in software. All USB
OTG flag bits are implemented as hardware set-only
bits. Additionally, these bits can only be cleared in
software by writing a ‘1’ to their locations (i.e.,
performing a BSET instruction). Writing a ‘0’ to a flag bit
(i.e., a BCLR instruction) has no effect.
Note 1: This data sheet is not intended to be a
comprehensive reference source. To com-
plement the information in this data sheet,
refer to Section 25. “USB On-The-Go
(OTG)” (DS70571) of the “dsPIC33E/
PIC24E Family Reference Manual”, which
is available from the Microchip web site
(www.microchip.com).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information. Note: The implementation and use of the USB
specifications and other third party
specifications or technology may require a
license from various entities, including,
but not limited to USB Implementers
Forum, Inc. (also referred to as USB-IF). It
is your responsibility to obtain more
information regarding any applicable
licensing obligations.
Note: Throughout this section, a bit that can only
be cleared by writing a ‘1’ to its location is
referred to as “Write ‘1’ to clear bit”. In reg-
ister descriptions, this function is indicated
by the descriptor, “K”.

23.0 10-BIT/12-BIT ANALOG-TO-
DIGITAL CONVERTER (ADC)
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 devices have two ADC
modules, ADC1 and ADC2. The ADC1 module
supports up to 32 analog input channels. The ADC2
module supports up to 16 analog input channels.
On ADC1, the AD12B bit (AD1CON1<10>) allows each
of the ADC modules to be configured by the user as
either a 10-bit, 4 Sample-and-Hold (S&H) ADC (default
configuration) or a 12-bit, 1 S&H ADC.
The ADC2 module only supports 10-bit operation with
4 S&H.
23.1 Key Features
The 10-bit ADC configuration has the following key
features:
• Successive Approximation (SAR) Conversion
• Conversion Speeds of up to 1.1 Msps
• Up to 32 Analog Input Pins
• External Voltage Reference Input Pins
• Simultaneous Sampling of up to Four Analog
Input Pins
• Automatic Channel Scan mode
• Selectable Conversion Trigger Source
• Selectable Buffer Fill modes
• Four Result Alignment Options (signed/unsigned,
fractional/integer)
• Operation during CPU Sleep and Idle modes
The 12-bit ADC configuration supports all the above
features, except:
• In the 12-bit configuration, conversion speeds of
up to 500 ksps are supported
• There is only one S&H amplifier in the 12-bit
configuration, so simultaneous sampling of
multiple channels is not supported.
Depending on the particular device pinout, the ADC
can have up to 32 analog input pins, designated AN0
through AN31. In addition, there are two analog input
pins for external voltage reference connections. These
voltage reference inputs can be shared with other ana-
log input pins. The actual number of analog input pins
and external voltage reference input configuration
depends on the specific device.
A block diagram of the ADC module is shown in
Figure 23-1. Figure 23-2 provides a diagram of the
ADC conversion clock period.
Note 1: This data sheet summarizes the features
of the dsPIC33EPXXX(GP/MC/MU)806/
810/814 and PIC24EPXXX(GP/GU)810/
814 families of devices. It is not intended
to be a comprehensive reference source.

23.2 ADC Helpful Tips
1. The SMPIx control bits in the ADxCON2 registers:
a) Determine when the ADC interrupt flag is set
and an interrupt is generated, if enabled.
b) When the CSCNA bit in the ADxCON2 reg-
ister is set to ‘1’, this determines when the
ADC analog scan channel list, defined in
the AD1CSSL/AD1CSSH registers, starts
over from the beginning.
c) When the DMA peripheral is not used
(ADDMAEN = 0), this determines when the
ADC Result Buffer Pointer to ADC1BUF0-
ADC1BUFF gets reset back to the
beginning at ADC1BUF0.
d) When the DMA peripheral is used
(ADDMAEN = 1), this determines when the
DMA Address Pointer is incremented after a
sample/conversion operation. ADC1BUF0 is
the only ADC buffer used in this mode. The
ADC Result Buffer Pointer to ADC1BUF0-
ADC1BUFF gets reset back to the beginning
at ADC1BUF0. The DMA address is incre-
mented after completion of every 32nd
sample/conversion operation. Conversion
results are stored in the ADC1BUF0 register
for transfer to RAM using DMA.
2. When the DMA module is disabled
(ADDMAEN = 0), the ADC has 16 result buffers.
ADC conversion results are stored sequentially
in ADC1BUF0-ADC1BUFF, regardless of which
analog inputs are being used subject to the
SMPIx bits and the condition described in 1c)
above. There is no relationship between the
ANx input being measured and which ADC
buffer (ADC1BUF0-ADC1BUFF) that the
conversion results will be placed in.
3. When the DMA module is disabled
(ADDMAEN = 1), the ADC module has only
1 ADC result buffer (i.e., ADC1BUF0) per ADC
peripheral and the ADC conversion result must
be read, either by the CPU or DMA controller,
before the next ADC conversion is complete to
avoid overwriting the previous value.
4. The DONE bit (ADxCON1<0>) is only cleared at
the start of each conversion and is set at the
completion of the conversion, but remains set
indefinitely, even through the next sample phase
until the next conversion begins. If application
code is monitoring the DONE bit in any kind of
software loop, the user must consider this
behavior because the CPU code execution is
faster than the ADC. As a result, in Manual
Sample mode, particularly where the user’s
code is setting the SAMP bit (ADxCON1<1>),
the DONE bit should also be cleared by the user
application just before setting the SAMP bit.

25.0 COMPARATOR MODULE The comparator module provides three comparators
that can be configured in different ways. As shown in
Figure 25-1, individual comparator options are
specified by the comparator module’s Special Function
Register (SFR) control bits.
These options allow users to:
• Select the edge for trigger and interrupt generation
• Configure the comparator voltage reference and
band gap
• Configure output blanking and masking
The comparator operating mode is determined by the
input selections (i.e., whether the input voltage is
compared to a second input voltage or to an internal
voltage reference).

26.0 REAL-TIME CLOCK AND
CALENDAR (RTCC)
This chapter discusses the Real-Time Clock and
Calendar (RTCC) module and its operation.
Some of the key features of this module are:
• Time: Hours, Minutes and Seconds
• 24-Hour Format (military time)
• Calendar: Weekday, Date, Month and Year
• Alarm Configurable
• Year Range: 2000 to 2099
• Leap Year Correction
• BCD Format for Compact Firmware
• Optimized for Low-Power Operation
• User Calibration with Auto-Adjust
• Calibration Range: ±2.64 Seconds Error per Month
• Requirements: External 32.768 kHz Clock Crystal
• Alarm Pulse or Seconds Clock Output on RTCC Pin
The RTCC module is intended for applications where
accurate time must be maintained for extended periods
with minimum to no intervention from the CPU. The
RTCC module is optimized for low-power usage to pro-
vide extended battery lifetime while keeping track of
time.
The RTCC module is a 100-year clock and calendar
with automatic leap year detection. The range of the
clock is from 00:00:00 (midnight) on January 1, 2000 to
23:59:59 on December 31, 2099.
The hours are available in 24-hour (military time)
format. The clock provides a granularity of one second
with half-second visibility to the user.
Note 1: This data sheet summarizes the features
of the dsPIC33EPXXX(GP/MC/MU)806/
810/814 and PIC24EPXXX(GP/GU)810/
814 families of devices. It is not intended
to be a comprehensive reference source.

26.1 Writing to the RTCC Timer
The user application can configure the time and
calendar by writing the desired seconds, minutes,
hours, weekday, date, month and year to the RTCC
registers. Under normal operation, writes to the RTCC
Timer registers are not allowed. Attempted writes will
appear to execute normally, but the contents of the
registers will remain unchanged. To write to the RTCC
register, the RTCWREN bit (RCFGCAL<13>) must be
set. Setting the RTCWREN bit allows writes to the
RTCC registers. Conversely, clearing the RTCWREN
bit prevents writes.
To set the RTCWREN bit, the following procedure must
be executed. The RTCWREN bit can be cleared at any
time:
1. Write 0x55 to NVMKEY.
2. Write 0xAA to NVMKEY.
3. Set the RTCWREN bit using a single-cycle
instruction.
The RTCC module is enabled by setting the RTCEN bit
(RCFGCAL<15>). To set or clear the RTCEN bit, the
RTCWREN bit (RCFGCAL<13>) must be set.
If the entire clock (hours, minutes and seconds) needs
to be corrected, it is recommended that the RTCC
module should be disabled to avoid coincidental write
operation when the timer increments. Therefore, it
stops the clock from counting while writing to the RTCC
Timer register.

27.1 Overview
The CRC module can be programmed for CRC
polynomials of up to the 32nd order, using up to 32 bits.
Polynomial length, which reflects the highest exponent
in the equation, is selected by the PLEN<4:0> bits
(CRCCON2<4:0>).
The CRCXORL and CRCXORH registers control which
exponent terms are included in the equation. Setting a
particular bit includes that exponent term in the
equation; functionally, this includes an XOR operation
on the corresponding bit in the CRC engine. Clearing
the bit disables the XOR.
For example, consider two CRC polynomials, one a
16-bit equation and the other a 32-bit equation:
To program these polynomials into the CRC generator,
set the register bits as shown in Tab le 2 7 - 1.
Note that the appropriate positions are set to ‘1’ to indicate
that they are used in the equation (for example, X26 and
X23). The 0 bit required by the equation is always XORed;
thus, X0 is a don’t care. For a polynomial of length, N, it is
assumed that the Nth bit will always be used, regardless
of the bit setting. Therefore, for a polynomial length of 32,
there is no 32nd bit in the CRCxOR register.

29.0 SPECIAL FEATURES
dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 devices include
several features intended to maximize application
flexibility and reliability, and minimize cost through
elimination of external components. These are:
• Flexible Configuration
• Watchdog Timer (WDT)
• Code Protection and CodeGuard™ Security
• JTAG Boundary Scan Interface
• In-Circuit Serial Programming™ (ICSP™)
• In-Circuit Emulation
29.1 Configuration Bits
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 devices provide
nonvolatile memory implementation for device Configu-
ration bits. Refer to Section 30. “Device Configuration”
(DS70618) of the “dsPIC33E/PIC24E Family Reference
Manual” for more information on this implementation.
The Configuration bits can be programmed (read as
‘0’), or left unprogrammed (read as ‘1’), to select
various device configurations. These bits are mapped,
starting at program memory location, 0xF80000.
The individual Configuration bit descriptions for the
Configuration registers are shown in Table 29-2.
Note that address, 0xF80000, is beyond the user
program memory space. It belongs to the configuration
memory space (0x800000-0xFFFFFF), which can only
be accessed using table reads and table writes.
To prevent inadvertent configuration changes during
code execution, some programmable Configuration
bits are write-once. For such bits, changing a device
configuration requires that the device be reset. For
other Configuration bits, the device configuration
changes immediately after an RTSP operation. The
RTSP effect column in Table 29-2 indicates when the
device configuration changes after a bit is modified
using RTSP.
The device Configuration register map is shown in
Table 29-1.
Note: This data sheet summarizes the features of
the dsPIC33EPXXX(GP/MC/MU)806/810/
814 and PIC24EPXXX(GP/GU)810/814
families of devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to the related section of the

dsPIC33EPXXX(GP/MC/MU)806/810/814 and PIC24EPXXX(GP/GU)810/814
29.2 On-Chip Voltage Regulator
All of the dsPIC33EPXXX(GP/MC/MU)806/810/814
and PIC24EPXXX(GP/GU)810/814 devices power
their core digital logic at a nominal 1.8V. This can create
a conflict for designs that are required to operate at a
higher typical voltage, such as 3.3V. To simplify system
design, all devices in the dsPIC33EPXXX(GP/MC/
MU)806/810/814 and PIC24EPXXX(GP/GU)810/814
family incorporate an on-chip regulator that allows the
device to run its core logic from VDD.
The regulator provides power to the core from the other
VDD pins. A low-ESR (less than 1 Ohms) capacitor
(such as tantalum or ceramic) must be connected to the
VCAP pin (Figure 29-1). This helps to maintain the
stability of the regulator. The recommended value for
the filter capacitor is provided in Table 32-13 located in
Section 32.0 “Electrical Characteristics”.
FIGURE 29-1: CONNECTIONS FOR THE
ON-CHIP VOLTAGE
REGULATOR(1,2,3)
29.3 Brown-out Reset (BOR)
The Brown-out Reset module is based on an internal
voltage reference circuit that monitors the regulated
supply voltage, VCAP. The main purpose of the BOR
module is to generate a device Reset when a brown-
out condition occurs. Brown-out conditions are
generally caused by glitches on the AC mains (for
example, missing portions of the AC cycle waveform
due to bad power transmission lines, or voltage sags
due to excessive current draw when a large inductive
load is turned on).
A BOR generates a Reset pulse, which resets the
device. The BOR selects the clock source based on the
device Configuration bit values (FNOSC<2:0> and
POSCMD<1:0>).
If an oscillator mode is selected, the BOR activates the
Oscillator Start-up Timer (OST). The system clock is
held until OST expires. If the PLL is used, the clock is
held until the LOCK bit (OSCCON<5>) is ‘1’.
Concurrently, the Power-up Timer (PWRT) Time-out
(TPWRT) is applied before the internal Reset is
released. If TPWRT = 0 and a crystal oscillator is
being used, then a nominal delay of TFSCM is
applied. The total delay in this case is TFSCM. Refer
to Parameter SY35 in Table 32-22 of Section 32.0
“Electrical Characteristics” for specific TFSCM
values.
The BOR Status bit (RCON<1>) is set to indicate that a
BOR has occurred. The BOR circuit, continues to oper-
ate while in Sleep or Idle modes and resets the device
should VDD fall below the BOR threshold voltage.
Note: It is important for the low-ESR capacitor to
be placed as close as possible to the VCAP
pin.
Note 1: These are typical operating voltages. Refer
to Table 32-13 located in Section 32.1
“DC Characteristics” for the full operating
ranges of VDD and VCAP.
2: It is important for the low-ESR capacitor to
be placed as close as possible to the VCAP
pin.
3: Typical VCAP pin voltage is 1.8V when
VDD VDDMIN.

29.4 Watchdog Timer (WDT)
For dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 devices, the WDT is
driven by the LPRC Oscillator. When the WDT is
enabled, the clock source is also enabled.
29.4.1 PRESCALER/POSTSCALER
The nominal WDT clock source from LPRC is 32 kHz.
This feeds a prescaler that can be configured for either
5-bit (divide-by-32) or 7-bit (divide-by-128) operation.
The prescaler is set by the WDTPRE Configuration bit.
With a 32 kHz input, the prescaler yields a nominal
WDT Time-out (TWDT) period of 1 ms in 5-bit mode or
4 ms in 7-bit mode.
A variable postscaler divides down the WDT prescaler
output and allows for a wide range of time-out periods.
The postscaler is controlled by the WDTPOST<3:0>
Configuration bits (FWDT<3:0>), which allow the selec-
tion of 16 settings, from 1:1 to 1:32,768. Using the
prescaler and postscaler, time-out periods ranging from
1 ms to 131 seconds can be achieved.
The WDT, prescaler and postscaler are reset:
• On any device Reset
• On the completion of a clock switch, whether
invoked by software (i.e., setting the OSWEN bit
after changing the NOSC bits) or by hardware
(i.e., Fail-Safe Clock Monitor)
• When a PWRSAV instruction is executed
(i.e., Sleep or Idle mode is entered)
• When the device exits Sleep or Idle mode to
resume normal operation
•By a CLRWDT instruction during normal execution
29.4.2 SLEEP AND IDLE MODES
If the WDT is enabled, it continues to run during Sleep or
Idle modes. When the WDT time-out occurs, the device
wakes the device and code execution continues from
where the PWRSAV instruction was executed. The corre-
sponding SLEEP or IDLE bits (RCON<3,2>) need to be
cleared in software after the device wakes up.
29.4.3 ENABLING WDT
The WDT is enabled or disabled by the FWDTEN
Configuration bit in the FWDT Configuration register.
When the FWDTEN Configuration bit is set, the WDT is
always enabled.
The WDT can be optionally controlled in software
when the FWDTEN Configuration bit has been
programmed to ‘0’. The WDT is enabled in software
by setting the SWDTEN control bit (RCON<5>). The
SWDTEN control bit is cleared on any device Reset.
The software WDT option allows the user application
to enable the WDT for critical code segments and
disable the WDT during non-critical segments for
maximum power savings.
The WDT flag bit, WDTO (RCON<4>), is not automatically
cleared following a WDT time-out. To detect subsequent
WDT events, the flag must be cleared in software.
FIGURE 29-2: WDT BLOCK DIAGRAM
Note: The CLRWDT and PWRSAV instructions
clear the prescaler and postscaler counts
when executed.
Note: If the WINDIS bit (FWDT<6>) is cleared,
the CLRWDT instruction should be executed
by the application software only during the
last 1/4 of the WDT period. This CLRWDT
instruction window can be determined by
using a timer. If a CLRWDT instruction is
executed before this window, a WDT Reset
occurs.

29.5 JTAG Interface
dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 devices implement a
JTAG interface, which supports boundary scan device
testing. Detailed information on this interface is
provided in future revisions of the document.
29.6 In-Circuit Serial Programming
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 devices can be serially
programmed while in the end application circuit. This is
done with two lines for clock and data, and three other
lines for power, ground and the programming
sequence. Serial programming allows customers to
manufacture boards with unprogrammed devices and
then program the digital signal controller just before
shipping the product. Serial programming also allows
the most recent firmware or a custom firmware to be
programmed. Refer to the “dsPIC33E/PIC24E Flash
Programming Specification” (DS70619) for details
about In-Circuit Serial Programming (ICSP).
Any of the three pairs of programming clock/data pins
can be used:
• PGEC1 and PGED1
• PGEC2 and PGED2
• PGEC3 and PGED3
29.7 In-Circuit Debugger
When MPLAB® ICD 3 or REAL ICE™ is selected as a
debugger, the in-circuit debugging functionality is
enabled. This function allows simple debugging
functions when used with MPLAB IDE. Debugging
functionality is controlled through the PGECx (Emula-
tion/Debug Clock) and PGEDx (Emulation/Debug
Data) pin functions.
Any of the three pairs of debugging clock/data pins can
be used:
• PGEC1 and PGED1
• PGEC2 and PGED2
• PGEC3 and PGED3
To use the in-circuit debugger function of the device,
the design must implement ICSP connections to
MCLR, VDD, VSS and the PGECx/PGEDx pin pair. In
addition, when the feature is enabled, some of the
resources are not available for general use. These
resources include the first 80 bytes of data RAM and
two I/O pins.
29.8 Code Protection and
CodeGuard™ Security
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 devices offer basic
implementation of CodeGuard Security that supports
only General Segment (GS) security. This feature helps
protect individual Intellectual Property in collaborative
system designs.
When coupled with software encryption libraries,
CodeGuard Security can be used to securely update
Flash even when multiple IPs reside on the single chip.
The code protection features vary depending on the
actual dsPIC33E implemented. The following sections
provide an overview of these features.
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 devices do not support
Boot Segment (BS), Secure Segment (SS) and RAM
protection.
Note: Refer to Section 24. “Programming
and Diagnostics” (DS70608) of the
“dsPIC33E/PIC24E Family Reference
Manual” for further information on usage,
configuration and operation of the JTAG
interface.
Note: Refer to Section 23. “CodeGuard™

30.0 INSTRUCTION SET SUMMARY
The dsPIC33EP instruction set is almost identical to
that of the dsPIC30F and dsPIC33F. The PIC24EP
instruction set is almost identical to that of the PIC24F
and PIC24H.
Most instructions are a single program memory word
(24 bits). Only three instructions require two program
memory locations.
Each single-word instruction is a 24-bit word, divided
into an 8-bit opcode, which specifies the instruction
type and one or more operands, which further specify
the operation of the instruction.
The instruction set is highly orthogonal and is grouped
into five basic categories:
• Word or byte-oriented operations
• Bit-oriented operations
• Literal operations
• DSP operations
• Control operations
Table 30-1 lists the general symbols used in describing
the instructions.
The dsPIC33E instruction set summary in Ta b l e 3 0 - 2
lists all the instructions, along with the status flags
affected by each instruction.
Most word or byte-oriented W register instructions
(including barrel shift instructions) have three
operands:
• The first source operand, which is typically a
register ‘Wb’ without any address modifier
• The second source operand, which is typically a
register ‘Ws’ with or without an address modifier
• The destination of the result, which is typically a
register ‘Wd’ with or without an address modifier
However, word or byte-oriented file register instructions
have two operands:
• The file register specified by the value ‘f’
• The destination, which could be either the file
register ‘f’ or the W0 register, which is denoted as
‘WREG’
Most bit-oriented instructions (including simple rotate/
shift instructions) have two operands:
• The W register (with or without an address
modifier) or file register (specified by the value of
‘Ws’ or ‘f’)
• The bit in the W register or file register (specified
by a literal value or indirectly by the contents of
register ‘Wb’)
The literal instructions that involve data movement can
use some of the following operands:
• A literal value to be loaded into a W register or file
register (specified by ‘k’)
• The W register or file register where the literal
value is to be loaded (specified by ‘Wb’ or ‘f’)
However, literal instructions that involve arithmetic or
logical operations use some of the following operands:
• The first source operand, which is a register ‘Wb’
without any address modifier
• The second source operand, which is a literal
value
• The destination of the result (only if not the same
as the first source operand), which is typically a
register ‘Wd’ with or without an address modifier
The MAC class of DSP instructions can use some of the
following operands:
• The accumulator (A or B) to be used (required
operand)
• The W registers to be used as the two operands
• The X and Y address space prefetch operations
• The X and Y address space prefetch destinations
• The accumulator write-back destination
The other DSP instructions do not involve any
multiplication and can include:
• The accumulator to be used (required)
• The source or destination operand (designated as
Wso or Wdo, respectively) with or without an
address modifier
• The amount of shift specified by a W register ‘Wn’
or a literal value
The control instructions can use some of the following
operands:
• A program memory address
• The mode of the table read and table write
instructions

Most instructions are a single word. Certain double-word
instructions are designed to provide all the required
information in these 48 bits. In the second word, the
8 MSbs are ‘0’s. If this second word is executed as an
instruction (by itself), it executes as a NOP.
The double-word instructions execute in two instruction
cycles.
Most single-word instructions are executed in a single
instruction cycle, unless a conditional test is true, or the
Program Counter is changed as a result of the
instruction, or a PSV or table read is performed. In these
cases, the execution takes multiple instruction cycles
with the additional instruction cycle(s) executed as a
NOP. Certain instructions that involve skipping over the
subsequent instruction require either two or three cycles
if the skip is performed, depending on whether the
instruction being skipped is a single-word or two-word
instruction. Moreover, double-word moves require two
cycles.
Note: For more details on the instruction set,
refer to the “16-bit MCU and DSC
Programmer’s Reference Manual”

processor, and one-step driver, and can run on multiple
platforms.
31.4 MPASM Assembler
The MPASM Assembler is a full-featured, universal
macro assembler for PIC10/12/16/18 MCUs.
The MPASM Assembler generates relocatable object
files for the MPLINK Object Linker, Intel® standard HEX
files, MAP files to detail memory usage and symbol
reference, absolute LST files that contain source lines
and generated machine code and COFF files for
debugging.
The MPASM Assembler features include:
• Integration into MPLAB IDE projects
• User-defined macros to streamline
assembly code
• Conditional assembly for multi-purpose

objects created by the MPASM Assembler and the
MPLAB C18 C Compiler. It can link relocatable objects
from precompiled libraries, using directives from a
linker script.
The MPLIB Object Librarian manages the creation and
modification of library files of precompiled code. When
a routine from a library is called from a source file, only
the modules that contain that routine will be linked in
with the application. This allows large libraries to be
used efficiently in many different applications.
The object linker/library features include:
• Efficient linking of single libraries instead of many
smaller files
• Enhanced code maintainability by grouping
related modules together
• Flexible creation of libraries with easy module
listing, replacement, deletion and extraction
31.6 MPLAB Assembler, Linker and
Librarian for Various Device
Families
MPLAB Assembler produces relocatable machine
code from symbolic assembly language for PIC24,
PIC32 and dsPIC devices. MPLAB C Compiler uses
the assembler to produce its object file. The assembler
generates relocatable object files that can then be
archived or linked with other relocatable object files and
archives to create an executable file. Notable features
of the assembler include:
• Support for the entire device instruction set
• Support for fixed-point and floating-point data
• Command line interface
• Rich directive set
• Flexible macro language
• MPLAB IDE compatibility

Note 1: IDD is primarily a function of the operating voltage and frequency. Other factors, such as I/O pin loading
and switching rate, oscillator type, internal code execution pattern and temperature, also have an impact
on the current consumption. The test conditions for all IDD measurements are as follows:
• Oscillator is configured in EC mode and external clock is active, OSC1 is driven with external square
wave from rail-to-rail (EC Clock Overshoot/Undershoot < 250 mV required)
• CLKO is configured as an I/O input pin in the Configuration Word
• All I/O pins are configured as inputs and pulled to VSS
•MCLR = VDD, WDT and FSCM are disabled

Note 1: Data in “Typ” column is at 3.3V, +25°C unless otherwise stated.
2: Instruction cycle period (TCY) equals two times the input oscillator time base period. All specified values
are based on characterization data for that particular oscillator type under standard operating conditions
with the device executing code. Exceeding these specified limits may result in an unstable oscillator
operation and/or higher than expected current consumption. All devices are tested to operate at
“Minimum” values with an external clock applied to the OSC1 pin. When an external clock input is used,
the “Maximum” cycle time limit is “DC” (no clock) for all devices.
3: Measurements are taken in EC mode. The CLKO signal is measured on the OSC2 pin.
4: This parameter is characterized, but not tested in manufacturing.

Note the following details of the code protection feature on Microchip devices:
• Microchip products meet the specification contained in their particular Microchip Data Sheet.
• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Microchip received ISO/TS-16949:2009 certification for its worldwide
headquarters, design and wafer fabrication facilities in Chandler and
Tempe, Arizona; Gresham, Oregon and design centers in California
and India. The Company’s quality system processes and procedures
are for its PIC® MCUs and dsPIC® DSCs, KEELOQ® code hopping
devices, Serial EEPROMs, microperipherals, nonvolatile memory and
analog products. In addition, Microchip’s quality system for the design
and manufacture of development systems is ISO 9001:2000 certified.
