Appendix A. Watchdog Timer

The Watchdog Timer is a device to ensure that standalone

systems can always recover from catastrophic conditions that

cause the CPU to crash. This condition may have occurred by

external EMI or a software bug. When the CPU stops working

normally, hardware on the board will perform hardware reset

(cold boot) to bring the system back to a known state.

Three I/O ports control the Watchdog Timer.
