COM Express Module COM-TC
1.1 Introduction
The original embedded board manufacturer, is pleased to announce
the debut of their new generation COM Express Module-- COM-TC.
The COM-TC is a cutting-edge product that provides high performance
and low power consumption in the embedded market.
COM-TC adopts the latest Intel
®
Atom™ E620/E680 processor. The
system memory deploys with onboard DDR2 667/800 memory up to 2
GB. In addition, Realtek RTL8211CL supports 10/100/1000Base-TX
that allows faster network connections. This model applies two
PCI-Express[x1], 4-bit SDIO multiplexed with GPIO pins, one LPC bus,
and one SMBus. Moreover, one SATA SSD onboard, one or two
SATA 3.0Gb/s, and one PATA are configured on the COM-TC.
COM-TC also equips seven USB2.0 (six USB Host and one USB
Client) for flexible I/O expansions.
The display of COM-TC supports LVDS/SDVO independent display
and High definition video 2D/3D encoder/decoder. This brand new
COM Express Module is developed to cater to the requirements of
Automation, Medical, ticket machine, transportation, gaming, KIOSK,
and POS/POI applications.

2.1 Safety Precautions
Always completely disconnect the power cord
from your board whenever you are working on
it. Do not make connections while the power is
on, because a sudden rush of power can
damage sensitive electronic components.
Always ground yourself to remove any static
charge before touching the board. Modern
electronic devices are very sensitive to static
electric charges. Use a grounding wrist strap at
all times. Place all electronic components on a
static-dissipative surface or in a static-shielded
bag when they are not in the chassis

3.1 System Test and Initialization
These routines test and initialize board hardware. If the routines
encounter an error during the tests, you will either hear a few short
beeps or see an error message on the screen. There are two kinds
of errors: fatal and non-fatal. The system can usually continue the
boot up sequence with non-fatal errors.
System configuration verification
These routines check the current system configuration against the
values stored in the CMOS memory. If they do not match, the
program outputs an error message. You will then need to run the
BIOS setup program to set the configuration information in memory.
There are three situations in which you will need to change the
CMOS settings:
1. You are starting your system for the first time
2. You have changed the hardware attached to your system
3. The CMOS memory has lost power and the configuration
information has been erased.
The COM-TC CMOS memory has an integral lithium battery backup
for data retention. However, you will need to replace the complete
unit when it finally runs down.

3.2 AMI BIOS Setup
AMI BIOS ROM has a built-in Setup program that allows users to
modify the basic system configuration. This type of information is
stored in battery-backed CMOS RAM so that it retains the Setup
information when the power is turned off.
Entering Setup
Power on the computer and press <Del> or <F2> immediately. This
will allow you to enter Setup.
Main
Set the date, use tab to switch between date elements.
Advanced
Enable disable boot option for legacy network devices.
Chipset
host bridge parameters.
Boot
Enables/disable quiet boot option.
Security
Set setup administrator password.
Save&Exit
Exit system setup after saving the changes.

A.1 General Information
The COM-TC utilizes EC fucntion as its watchdog timer Controller.
The other Watchdog timer is set to second or minute and the range is 1
to 255 seconds or minutes.
When the timeout has occurred, that will generate a status bit to indicate
it and write one will be clear.
A.2 Access Interface
The EC provides LPC access interface, to read/write internal registers.
The index of LPC interface is 610(Hex) , the data of LPC interface is 611
(Hex) .
The LPC I/O interface wil be mapping to virtual memory address . The
EC/Host communication interface registers can be accedssed on follow
register.
