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 enabled in BIOS.
Note: When enabled, the user needs to write
their own application software in order to dis-
able the Watch Dog Timer.
