ADFM
If the A/D F
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
Unimplemented: Read as ‘0’
ACQT2:ACQT0: A/D Acquisition Time Select bits
111 = 20 T
110 = 16 T
101 = 12 T
100 = 8 T
011 = 6 T
010 = 4 T
001 = 2 T
000 = 0 T
ADCS2:ADCS0: A/D Conversion Clock Select bits
