Appendix A Programming the Watchdog Timer

 

A - 2

 

A.1 Programming 

EMB-900M 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.
