4.20 Digital Windowed Watchdog

This device includes a digital windowed watchdog (DWWD) module that protects against runaway code
execution.

The DWWD module allows the application to configure the time window within which the DWWD module
expects the application to service the watchdog. A watchdog violation occurs if the application services the
watchdog outside of this window, or fails to service the watchdog at all. The application can choose to
generate a system reset or an ESM group2 error signal in case of a watchdog violation.

The watchdog is disabled by default and must be enabled by the application. Once enabled, the watchdog
can only be disabled upon a system reset.
