Overview

The Watchdog Timer is useful in monitoring the condition where a CPU and software get into an unrecoverable unknown or “stuck” state. Software periodically “kicks” the watchdog by writing to it to reset its timeout counters.

The Watchdog Timer module is a programmable reset controller module. The module is a standard APB Slave component peripheral; the Watchdog Timer registers are accessed through this interface. The module implements a 32-bit down counter with a selectable prescaler in order to produce a delayed reset signal and a watchdog reset signal, as well as a warning interrupt.
