1.8.7 Watchdog timer output (JWDT1)
The SIMB-982 contains a watchdog timer that will reset the CPU. This feature means
the SIMB-982 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.
