Watch Dog

J31 controls Watch Dog, a system monitor that takes action when a software application freezes the system. Pins 1-2 will have WD re- set the system if a program freezes. Pins 2-3 will generate a non-maskable interrupt for the pro- gram that has frozen (requires soft- ware implementation). Watch Dog must also be enabled in BIOS.
