Watchdog timer operation during power-down
The watchdog timer can be kept on during normal conditions when READY is high (depending
on the user’s settings).
In this condition, the watchdog timer can be disabled or enabled. If the watchdog timer is
enabled, the timer needs to be cleared before the programmed count of the timer is reached. If
the programmed count is reached, the STBY will be asserted.
It is advisable not to enable the watchdog timer during normal operation.
