1.5.4 Watchdog timer configuration (JP4)

An on-board watchdog timer reduces the chance of disruptions caused

by EMP (electro-magnetic pulse) interference. It is an invaluable

protective device for standalone or unmanned applications. Setup

involves two jumpers and running the control software. (Refer to

Appendix A.)

When the watchdog timer is enabled and the CPU shuts down, the

watchdog timer will automatically either reset the system or generate

an interrupt on IRQ 11, depending on the setting of jumper JP4, as

shown below:
