Appendix B. Watch-Dog Timer

The Watch-Dog Timer is provided to ensure that standalone
systems can always recover from catastrophic conditions that
caused the CPU to crash. This condition may have occurred by
external EMI or a software bug. When the CPU stops working
correctly, hardware on the board will either perform a hardware
reset (cold boot) or a non-maskable interrupt (NMI) to bring the
system back to a known state.
