Appendix A Programming the Watchdog Timer 

A-2 

A.1 Programming 

AEC-6905 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.
