5.7 Watchdog Timer Configuration
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.)
5.7.1 Watchdog activity selection (JP7)
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 JP7 as shown below:
