1.1 Introduction
The AEC-6831 is an Embedded Control PC with Intel Atom
Processor. The Anti-vibration and high temperature tolerances
are the main design features of the AEC-6831. This allows the
AEC-6831 to be installed in a rugged transportation environment
despite high ambient vibration and temperature.
In addition to the Atom CPU, the AEC-6831 have DVI + VGA
output for video output and DC power supply is commonly used
in most vehicles and factory equipments, the AEC-6831 can
powered by a DC 9~30V input with low power consumption and
high performance. You can also choose an additional external
AC power adapter for power redundancy purposes.
Transportation has become part of most people’s life and forms a
necessary part of their lifestyle. From cars to trains to ships, we
rely on those tools a lot. The AEC-6831 is designed to improve
transportation control and enhance the quality of our lives.

Embedded Controller AEC-6831
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. Non-fatal error messages
usually appear on the screen along with the following instructions:
Press <F1> to RESUME
Write down the message and press the F1 key to continue the boot
up sequence.
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 AEC-6831 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 Award BIOS Setup
Awards 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.

Power on the computer and press <Del> immediately. This will
allow you to enter Setup.

Appendix A Programming the Watchdog Timer A-1
Embedded Controller AEC-6831
A.1 Programming
AEC-6831 utilizes ITE 8781 chipset as its watchdog
timer controller. Below are the procedures to complete its
configuration and the AAEON initial watchdog timer
program is also attached based on which you can
develop customized program to fit your application.
Configuring Sequence Description
After the hardware reset or power-on reset, the ITE 8781 enters the
normal mode with all logical devices disabled except
KBC. The initial state (enable bit ) of this logical device (KBC) is
determined by the state of pin 121 (DTR1#) at the falling edge of
the system reset during power-on reset.
Appendix A Programming the Watchdog Timer A-2
Embedded Controller AEC-6831
There are three steps to complete the configuration setup: (1) Enter
the MB PnP Mode; (2) Modify the data of configuration re gisters; (3)
Exit the MB PnP Mode. Undesired result may occur if the MB PnP
Mode is not exited normally.
(1) Enter the MB PnP Mode
To enter the MB PnP Mode, four special I/O write operations are to
be performed during Wait for Key st ate. To ensure the initial st ate of
the key-check logic, it is necessary to p erform four write opera-tio ns
to the Special Address port (2EH). Two different enter keys are
provided to select configuration ports (2Eh/2Fh) of the next step.
(2) Modify the Data of the Regist ers
All configuration registers can be accessed after entering the MB
PnP Mode. Before accessing a selected register, the content of
Index 07h must be changed to the LDN to which the register
belongs, except some Global registers.
(3) Exit the MB PnP Mode
Set bit 1 of the configure control register (Index=02h) to 1 to exit the
MB PnP Mode.
Appendix A Programming the Watchdog Timer A-3
Embedded Controller AEC-6831
WatchDog Ti mer Configuration Registers
Configure Control (Index=02h)
This register is write only. Its values are not sticky; that is to say, a
hardware reset will automatically clear the bits, and does not
require the software to clear them.
