ADFM
If the A/D FRC clock source is selected, a delay of one T
clock starts. This allows the SLEEP instruction to be executed before starting a conversion.
ADFM: A/D Result Format Select bit
1 = Right justified
0 = Left justified
ADCAL: A/D Calibration bit
1 = Calibration is performed on the next A/D conversion
0 = Normal A/D Converter operation
