Appendix A Programming the Watchdog Timer

A - 2

A.1 Programming

ETX-821 utilizes ITE 8712 chipset as its watchdog timer

controller.

Below are the procedures to complete its configuration and

the AAEON intial 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 8712

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.
