1.8.3 Watchdog timer output (JWDT1)
The PCE-5120 contains a watchdog timer that will reset the CPU in the
event the CPU stops processing. This feature means the PCE-5120 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.
