Appendix B Programming the Watchdog Time

B-2

B.1 Programming

PCM-8300 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.
