Cautions 1. A write operation to bit 0 is ignored.
2. Changing the ADA0M1.ADA0FR2 to ADA0M1.ADA0FR0 bits is prohibited while A/D

If the ADA0M0, ADA0M2, ADA0S, ADA0PFM, and ADA0PFT registers are written in other
modes during A/D conversion (ADA0EF bit = 1), the following will be performed,
according to the mode.
