ADFM: A/D Result Formed Select bit
1 = Right justified
0 = Left justified
VCFG: Voltage Reference bit
1 = VREF pin
0 = VDD
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)
100 =Channel 04 (AN4)
101 =Channel 05 (AN5)
110 =Channel 06 (AN6)
111 =Channel 07 (AN7)
GO/DONE: A/D Conversion STATUS bit
1 = A/D conversion cycle in progress. Setting this bit starts an A/D conversion cycle.
This bit is automatically cleared by hardware when the A/D conversion has completed.
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
Legend:
R = Readable bit
- n = Value at POR
W = Writable bit
’1’ = Bit is set
U = Unimplemented bit, read as ‘0’
’0’ = Bit is cleared x = Bit is unknown

ADCS<2:0>: A/D Conversion Clock Select bits
000 = FOSC/2
001 = FOSC/8
010 = FOSC/32
x11 = FRC (clock derived from a dedicated internal oscillator = 500 kHz max)
100 = FOSC/4
