Watch Dog Enable/Disable
JWD controls the Watch Dog function.
Watch Dog is a system monitor that
can reboot the system when a software
application hangs. Jumping pins 1-2
will cause WD to reset the system if an
application hangs. Jumping pins 2-3
will generate a non-maskable interrupt
signal for the application that hangs.
See the table on the right for jumper
settings. Watch Dog must also be en-
abled in BIOS.
Note:
When enabled, the user needs to
write their own application software in
order to disable the Watch Dog Timer.
