ADFM
If the A/D RC clock source is selected, a delay of one T
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
ACQT<3:0>: A/D Acquisition Time Select bits
0000 = No delay (conversion starts immediately when GO/DONE is set)
0001 = 2 T
0010 = 4 T
0011 = 6 T
0100 = 8 T
0101 = 10 T
0110 = 12 T
0111 = 16 T
1000 = 20 T
1001 = 24 T
1010 = 28 T
1011 = 32 T
1100 = 36 T
1101 = 40 T
1110 = 48 T
1111 = 64 T
ADCS<2:0>: A/D Conversion Clock Select bits
000 = F
001 = F
010 = F
