5.1.1 Inter-Processor Communication
The Inter-Processor Communication (IPC) infrastructure between the Single Core
Modem and Application Subsystem is made up of a shared RAM between the
ARM9 and the C55x+, and a mailbox mechanism, on top of which the NetMux
software infrastructure exposes virtual channels to client components on both
Application (AP) and Baseband Processor (BP) sides.
5.1.2 Modem Software Architecture Overview
In this platform, the W3G processor includes a C55x+ DSP that runs the whole
2G/3G modem stack (supporting HSDPA/HSUPA) thus leaving the ARM9 fully
dedicated to native services.
This approach enables native services to run on the application processor without
the complexity of mixing hard real-time software (modem) with the applications.
The SCM architecture enables running all the modem functions: 2G and 3G
Signal Processing Layer (SPL) and 2G Stack and 3G stack on the SAM core
(C55x+ core).
Only what is needed to support modem functions is implemented on the C55x+
DSP core.
Interfaces have been split into 3 main domains: SPL, Stack and Infrastructure.
The Single Core Modem Software architecture is composed of the following
elements:
•
The Signal Processing Layer (SPL): this software layer implements the
physical layer.
o Uplink signal processing: channel coding and modulation, GSM
convolutional encoding and WCDMA convolutional encoding or
Turbo-encoding.
o Downlink signal processing: GSM equalization, GSM channel
decoding, WCDMA interface/control and WCDMA hardware
accelerators (3G Sub-System).
•
Stack component is the component from L1 Control to L3 handling all the
logical part of the GSM/GPRS/EGPRS and WCDMA protocols:
o GSM/GPRS/EDGE protocols: Layer 1, Layer2-Link Access Protocol
on the Dm channel (L2-LAPDm), GPRS Radio Link Control (RLC),
Logical Link Control (LLC) and the Sub-Network Dependent
Convergence Protocol (SNDCP).
Motorola Confidential Proprietary – Disclosed Under NDA
Page 10 of 43
MOTOROLA HSPA LGA Module User Guide
o WCDMA protocols: WCDMA Layer 1, Radio Resource Control
(RRC), WCDMA Radio Link Control (W-RLC), Broadcast Message
Control (BMC) and the Packet Data Convergence Protocol (PDCP).
o Dual Mode protocols: Layer 1, GPRS Radio Resource/Radio Resource
management (GRR/RR/RRC/RRLP), Mobility Management (MM),
GPRS Mobility Manager (GMM), Session Management (SM),
Intelligent Data Router (IDR) and Connection Management (CM),
which consists of Call Control (CC), Supplementary Services (SS) and
Short Message Management (SMS) entities. A new created entity is
the Translation Layer (TL) which allows the 2G/WCDMA Engine
Layer to interface with the AP (especially L3/L4 interface).
The Infrastructure: this is the component providing the low-level mechanisms required by
other SCM entities (Stack, SPL, IPC, AGPS and Audio control). It contains hardware
drivers required by the others components like interrupt, watchdog, GPIO, and also
entities for communicating with the application processor (IPC). Finally, it contains
modules to relay functions to the application processor like NVM proxy, SIM proxy and
Audio Proxy.
5.1.3 ARM9 Software Architecture Overview
The Application Software Architecture uses the MotoAndroid architecture. The
Android Linux kernel is made of the Linux Kernel with some additional patches
including alarm, ashmem, binder, power management, low memory killer, kernel
debugger, and logger. The Linux kernel version is 2.6.27 and includes several
improvements made by OHA to the reference release in kernel.org.
The layers provide a view in which system functionality is increasingly abstracted
from hardware at the bottom layer, towards user functionality at the top layer.
The Linux kernel provides the operating system kernel services. It separates all
higher layers from the device hardware. Android relies on Linux version 2.6.27
for core system services such as security, memory management, process
management, network stack, and driver model. The kernel also acts as an
abstraction layer between the hardware and the rest of the software stack.

8. LGA module Interfaces
8.1.1 LGA Interface Signals
The HTM1100-L connects with netbook, notebook or MID using LGA module interface
signals. HTM1100-L uses USB interface on the module to connect with netbook,
notebook or MID. Electrically the module will be seen as a USB device since it uses a
standard USB2.0 connection. Power is supplied by motherboard. A SIM card must be
provided by PC manufacturer for user authentication.
A Radio disable (W_Disable) signal is connected from PC to the card; this allows the
user to enable/disable RF activity (Airplane mode) with a hardware switch. The module
controls one of the PC’s LEDs to indicate RF activity has been disabled or enabled. This
is driven by the signal LED_WWAN_B.
To summarize main characteristics of LGA Module:
• Standard USB interface
• B+ (3.0V to 4.2V) power supply from motherboard is used. Filter caps must
be added on these lines based on the PCB design.
• Expected max current in worst case scenario (with VSWR = 4) is around 1.1A
averaged over 1sec, 2.75A averaged over 100µs.
• W_DISABLE is used to enable/disable RF activity: 30s to disable, 1s to
enable.
• PC WWAN LED is controlled by the module.
The following table shows signals on LGA interface. The I/O level of all the pins is 1.8V.

8.1.2 SIM Interface
A standard ISO7816 SIM interface has been used on the card. SIM card is connected to
the SIM controller on ARM9.
A SIM slot must be provided by PC manufacturer on the final platform. SIM signals do
not have ESD protection. ESD protection is expected to be provided by PC manufacturer
and SIM connector should ne placed as close possible to the module by following the
guidelines in ISO7816 specification.
SIM signals are routed through the LGA module interface. SIM signals are shown in the
previous section.
SIM detection is done by SW polling. SW polls to see if SIM is present or not. SIM_CD
line is tied to w_disable and SIM_CD is not used for SIM detection.
8.1.3 WWAN_LED
WWAN_LED status indicator is in compliance with WWAN_LED signal in PCIe
specification 1.2. WWAN_LED signal is capable of sinking to ground as specified in
PCIe Specification 1.2.
WWAN_LED signal is a status indicator and the indicator is used to drive LED on the
host. WWAN_LED cannot change the brightness of the LED. Host is expected to provide
the source for LED and also capability to manage the brightness.
8.1.4 Audio Interface
HTM1000-L module will have the capability to support PCM Audio and Analog Audio.
Hardware support has been implemented; however SW support has not been
implemented yet. SW support for PCM audio and Analog audio will be available in the
future. Contact Motorola Applications Engineering for details.

9. Communication with Host
This chapter describes the way the UMTS LGA module will communicate with
the Host, i.e. the PC.
9.1.1 Overview
The LGA module communicates with the host via the USB 2.0 link, and the
W_DISABLE# pin.
Figure 6: Communication between Host and LGA Module
Motorola Confidential Proprietary – Disclosed Under NDA
Page 21 of 43
MOTOROLA HSPA LGA Module User Guide
9.1.2 Link Details
Communication with the PC thru USB is made thru a composite driver. There is
only one enumeration which covers all the needs: final user, tests, factory, etc.
The details of this configuration are given by the figure below.
Figure 7: HTM1100-L Modem interface
The link between Card and PC is made of 3 data pipes:
•
USB LAN: used to connect test services as TCMD, Log, as on LJ. The
channel may also be used for NGP services.
•
ACM pipe 1: used for data connection. DUN services will send dial up AT
commands thru this channel. When a connection is established, PPP is
Motorola Confidential Proprietary – Disclosed Under NDA
Page 22 of 43
MOTOROLA HSPA LGA Module User Guide
used to transfer data across the link. On the LGA module side, IP frames
are routed directly (thru line discipline) to the appropriate Netmux
channel.
•
ACM pipe 2: this ACM pipe is used for all control which is not related to
DUN. It is used by the connection manager on the PC side.
On the LGA module, ADB is not added on top of these three pipes as no external
developer will ever use ADB tools to develop on this card. And for AP log, the
same feature can be achieved by setting the variable ADBHOST on the PC to the
LGA module IP address.
The W_DISABLE# signal is also used to notify the card to go into airplane mode (signal
is active low, so setting it to ground will set the card to airplane mode). Setting
W_DISABLE# to low triggers an event on SCIM, and causes de-registration which is
handled at CommDrv level.
9.1.3 Host Modem Wakeup Mechanism
HTM1100-L supports optional USB remote wakeup capability by enabling the remote
wakeup flag in USB configuration descriptor and using electrical signaling as described
in Section 7.1.7.7 of USB Spec 2.0 to remote wakeup USB host. However, some USB
controllers and/or USB host software may not support USB remote wakeup. Therefore,
GPIO signaling is used to support remote wakeup.
During USB enumeration, HTM110-L will always enable USB remote wakeup flag in
USB configuration descriptor by default. That is to say, bit 5 of bmAttributes in USB
configuration descriptor is always 1 (enable).
Remote wakeup is implemented in two ways:
9.1.3.1 Using USB inband signalling
If USB host (HW and SW) supports USB remote wakeup, the built-in USB remote
wakeup functionality in device and host controller is used, HOST_WAKE is kept in its
default state as input and it is not used.
9.1.3.2 Using Host_Wakeup pad of HTM1100-L
If USB host does not support USB remote wakeup, it should disable this capability (see
sections 9.1.1.6, 9.2.5.2 and 9.4.1 of USB Spec 2.0) by clearing (disable) this feature. The
standard request to clear this feature is 0x0001010000000000. USB host should disable this
feature during or after USB enumeration but before USB suspend happens. HTM1100-L
can acknowledge this request, disable USB remote wakeup functionality and configure
HOST_WAKE as output LOW. If HTM110-L USB device is suspended and needed to
wakeup host, it will assert HOST_WAKE high. This should generate an interrupt to host
and host should start a standard USB resume process. HTM110-L USB will de-assert
Motorola Confidential Proprietary – Disclosed Under NDA

HOST_WAKE to low when it gets resume interrupt. The Figure 1 shows the GPIO
remote wakeup signaling.

10. AT commands
The LGA module supports AT commands interface using TTY/ACM. There will be two
TTY ports supported for AT commands, and both allow all the AT commands. PC
Connection Manager client must use only one instance for PPP at any time. Since the PC
Connection Manager Client cannot execute AT commands when data is active using PPP,
a second TTY Port instance of AT parser was added to execute non-data commands like
SMS or SIM.
The PC Connection Manager client must use all the relevant dependent AT commands on
one instance of AT parser only. E.g. For CGACT to work CGDCONT and any other
dependent commands need to be issued on the same TTY port.
The LGA module supports only one PDP context/PPP and the Context ID 1 must be used.
AT parser allows only one PDP activation using AT+CGACT or ATD*99#, so any time
one PDP is active AT Parser returns an ERROR for the next PDP activation request.
LGA module supports only USIM based Phonebook and SMS.
LGA module supports 27.007 Rel5 Spec defined options and parameters and there are
some deviations from the specifications. Refer to HTM1000_AT_Commands_spec for
details.
LGA module AT parser checks the existence and validity of mandatory fields. If any
mandatory field is absent or validity check fails then LGA module AT parser returns
ERROR.
LGA module AT parser supports extended error reporting.
The PC Connection manager client must use ATD*99# to trigger the PPP and Data call
activation.
The values stored using any of the AT commands like CGDCONT are not persistent
across power cycle.
10.1 LGA module AT command interface allows the below mentioned
functionality on high level using Different AT commands:

11. NVM/FLASH
The LGA module uses Single Level Cell (SLC) Large Page (LP) NAND flash to store all
data. Flash block sizes is 128K, divided each in 64 pages of 2K each.. Default flash size
if fixed to 64 Mbytes.
NAND flash is shared for AP and BP needs, but can only be physically accessed by the
AP side.
12. RF Calibration/Phasing
All boards are calibrated and tested in order to meet 3GPP specifications with margins.
In 2G, output powers are calibrated for each PCL and with compensation over frequency.
2G Calibration points are then validated by testing output power levels in GMSK and
8PSK. Critical parameters such as modulation and switching spectrum are also tested.
RSSI levels are also calibrated across the range with frequency compensation. BLER and
BER level are measured to validate sensitivity meets expectations.
In 3G, output power is calibrated through the whole range (from below -55dBm up to the
maximum output power level for each band). The receive chain is calibrated for input
power levels. There are some compensations over frequency both in uplink and
downlink.
3G calibration points are also validated by checking output power together with ACLR
and EVM. BLER is measured is WCDMA for different transfer rates in order to validate
the downlink path.

17. Known Issues
17.1 LGA Module Power up Timing
Issue: Power is provided to LGA module using B+. To turn Off the power to the module
B+ should be dropped down to 550mv or lower. If the supply voltage stays between 550
to 1150mV and then ramps to 3.3V the module will not turn ON when it’s powered up.
Resolution: Caution should be taken to drop the supply voltage to below 550mv while
designing a platform. If the supply voltage does not drop down to 550mv or lower, time
lapse between power down and power up should be at least 250ms.
