Watchdog timer output (JWDT1)

The AIMB-701 contains a watchdog timer that will reset the CPU. This feature means
the AIMB-701 will recover from a software failure or an EMI problem. The JWDT1
jumper settings control the outcome of what the computer will do in the event the
watchdog timer is tripped.
