The watchdog is triggered by toggling the trigger bit (CR0, D19).
Note:
The active trigger window will be reset after each correct trigger write operation.
In case of reset (NReset low for 2ms) the trigger bit is set to “0”.
In case of a WD failure, the outputs (Lsx, Hsx, V2) are switched off and NReset is pulled low
for 2ms.
Writing to control register 0 without inverting the WD trigger bit is possible at any time.
