Watchdog timer output (JWDT1)
The AIMB-766 contains a watchdog timer that will reset the CPU. This feature means
the AIMB-766 will recover from a software failure or an EMI problem. The
JSETCOM2 jumper settings control the outcome of what the computer will do in the
event the watchdog timer is tripped.
