1.8.3 Watchdog timer output (J2)
The AIMB-740-6CB1 contains a watchdog timer that will reset the CPU
or send a signal to IRQ11 in the event the CPU stops processing. This fea-
ture means the AIMB-740-6CB1 will recover from a software failure or
an EMI problem. The J2 jumper settings control the outcome of what the
computer will do in the event the watchdog timer is tripped.
