Watch Dog
JWD1 controls the Watch Dog function. Watch Dog is a monitor that can reboot the system
when a software application hangs. Jumping pins 1-2 will cause Watch Dog to reset the
system if an application hangs. Jumping pins 2-3 will generate a non-maskable interrupt
signal for the application that hangs. Watch Dog must also be enabled in BIOS. The default
setting is Reset.
Note: When Watch Dog is enabled, the user needs to write their own application software
to disable it.
