1.8.3 Watchdog timer output (JWDT1)
The PCE-5125 contains a watchdog timer that will reset the CPU or send a signal to
IRQ11 in the event the CPU stops processing. This feature means the PCE-5125 will
recover from a software failure or an EMI problem. The JWDT1 jumper settings con-
trol the outcome of what the computer will do in the event the watchdog timer is
tripped.
