Appendix A Programming the Watchdog Timer 

A-2 

A.1 Programming 

AEC-6850 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.
