Notes:

1.

When selecting the digital filter by the INTi input filter select bit, use an INTi input HIGH width of either (1/digital filter clock

frequency × 3) or the minimum value of standard, whichever is greater.

2.

When selecting the digital filter by the INTi input filter select bit, use an INTi input LOW width of either (1/digital filter clock

frequency × 3) or the minimum value of standard, whichever is greater.
