17.2.5 Digital Watchdog (DWD)

The digital watchdog (DWD) is an optional safety diagnostic which can detect a runaway CPU and

generate either a reset or NMI (non-maskable interrupt) response. It generates resets or NMIs after a

programmable period, or if no correct key sequence was written to the RTIWDKEY register. Figure 17-8

illustrates the DWD.
