Product(s) - Obsolete Product(s) Note:

Obsolete Caution:

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.
