JWD1 controls the Watch Dog function. Watch Dog is a monitor that can reboot the system

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 must write their own application
software to disable it.
