Watch Dog
JWD1 controls the Watch Dog function. The 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. The Watch Dog must also be enabled in the BIOS. The
default setting is Reset.
Note: When Watch Dog is enabled, users need to write their own application software to
disable it.
