5.5 Watchdog Timer Configuration
An on-board 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.)
5.5.1 Watchdog activity selection (JP15)
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 JP15 as shown below:
