Watch Dog Enable/Disable
JWD controls the Watch Dog func-
tion. Watch Dog is a system monitor
that can reboot the system when a
software application is “hung up”. Pins
1-2 will cause WD to reset the system
if an application is hung up. Pins 2-3
will generate a non-maskable interrupt
signal for the application that is hung
up. See the table on the right for jump-
er settings. Watch Dog must also be
enabled in BIOS.
Note: When enabled, the user must
write their own application software in
order to disable the Watch Dog Timer.

tions associated with the connection
