1.8.3 Watchdog timer output (J4)
The DVMB-554E contains a watchdog timer that will reset the CPU or
send a signal to PIRQE in the event the CPU stops processing. This
feature means the DVMB-554E will recover from a software failure or an
EMI problem. The J4 jumper settings control the outcome of what the
computer will do in the event the watchdog timer is tripped.
