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.
