For a basic operation, follow these steps:

During the start-up time after enabling the AC, the output of the AC may be invalid.

The start-up time of the AC by itself is at most 2.5 ┬Ás. If an internal reference is used, the reference start-up time is normally longer than the AC start-up time.

To avoid the pin being tri-stated when the AC is disabled, the OUT pin must be configured as output in PORTx.DIR.
