clock (WDCLK) is the IRC.
The WWDT cannot be reset by software.
The WWDT interrupt is connected to slot # 7 in the Event router.
Internally resets chip if not reloaded during the programmable time-out period.
Optional windowed operation requires reload to occur between a minimum and
maximum time-out period, both programmable.
Optional warning interrupt can be generated at a programmable time prior to
watchdog time-out.
Programmable 24 bit timer with internal fixed pre-scaler.
Selectable time period from 1,024 watchdog clocks (T

Safe watchdog operation. Once enabled, requires a hardware reset or a Watchdog
reset to be disabled.
Incorrect feed sequence causes immediate watchdog reset if enabled.
The watchdog reload value can optionally be protected such that it can only be
changed after the “warning interrupt” time is reached.
Flag to indicate Watchdog reset.
The WWDT uses the IRC as a fixed clock source.
