When the A/D clock source is selected as F
cycle after the GO/DONE bit is set to allow the SLEEP instruction to be executed.
ADFM: A/D Conversion Result Format Select bit
1 = Right justified
0 = Left justified
Unimplemented: Read as ‘0’
ACQT<2:0>: A/D Acquisition time select bits. Acquisition time is the duration that the A/D charge hold-
ing capacitor remains connected to A/D channel from the instant the GO/DONE bit is set until conver-
sions begins.
