1.8.3 Watchdog timer output (J2)

The PCA-6009 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 PCA-6009 will recover from a software failure or an EMI
problem. The J2 jumper settings control the outcome of what the com-
puter will do in the event the watchdog timer is tripped.
