Watchdog Timer Configuration (J4)

An onboard watchdog timer reduces the chance of disruptions which EMP
(electromagnetic pulse) interference can cause. This is an invaluable protective
device for standalone or unmanned applications. Setup involves one jumper and
running the control software. (Refer to Appendix B.)
When the watchdog timer activates (i.e. CPU processing has come to a halt), it can
reset the system or generate an interrupt on IRQ11. This can be set via jumper J4
as shown below:
