54.3.1 Watchdog refresh mechanism

The watchdog resets the MCU if the watchdog counter is not refreshed. A robust refresh
mechanism makes it very unlikely that the watchdog can be refreshed by runaway code.

To refresh the watchdog counter, software must execute a refresh write sequence before
the timeout period expires. In addition, if window mode is used, software must not start
the refresh sequence until after the time value set in the WIN register. See the following
figure.

54.3.1.1 Window mode

Software finishing its main control loop faster than expected could be an indication of a
problem. Depending on the requirements of the application, the WDOG can be
programmed to force a reset when refresh attempts are early.
