bit 7
ADFM: A/D Result Formed Select bit
1 = Right justified
0 = Left justified
VCFG: Voltage Reference bit
1 = V
0 = V
Unimplemented: Read as zero
CHS2:CHS0: Analog Channel Select bits
000 =Channel 00 (AN0)
001 =Channel 01 (AN1)
010 =Channel 02 (AN2)
011 =Channel 03 (AN3)

GO/DONE: A/D Conversion STATUS bit
1 = A/D conversion cycle in progress. Setting this bit starts an A/D conversion cycle.
0 = A/D conversion completed/not in progress
ADON: A/D Conversion STATUS bit
1 = A/D converter module is operating
0 = A/D converter is shut-off and consumes no operating current

000 = F
001 = F
010 = F
x11 = F
100 = F
101 = F
110 = F
Unimplemented: Read as ‘0’.
