HOW TO USE WATCH-DOG TIMER

You could enable the watch-dog for when your application software monitors an

unexpected or not respond event, then the hardware timer generates a reset to reboot

your system. The watch-dog timer period (from enable to reset) was decided by the

jumper setting of the watch-dog time out period. Please refer the chapter of jumper

settings and connectors. During the period of enable to reset, you could still cancel

reset bt disabling the watch-dog.

EX.1: For DOS

Execute the DEBUG.EXE file under DOS, Then key-in i443. The system will reboot

automatically according to the time-out you set.

For example, if you want to Set 4 seconds for the time-out, you should set JP14: 4-8 ON

Enable

C:\DOS> DEBUG

-i443

Disable

C:\DOS>DEBUG

-i43

EX.2: For assemble Language

Enable :

MOV DX, 443H

IN AL, DX

Disable :

IN AL, 43H
