If the device is in fail-safe mode, the control registers are locked for writing. To change the
watchdog timing out of fail-safe mode, first the fail-safe condition must be solved, respective
confirmed from the microcontroller. Afterwards the new watchdog timing can be
programmed using the sequence from
condition can differ from the root cause of the fail safe the following diagram shows the
general procedure how to change the watchdog timing out of fail-safe mode.
shows the procedure to change watchdog timing with a previous watchdog failure, since this
is a special fail-safe scenario.
