bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7 ADFM: A/D Result Formed Select bit
1 = Right justified
0 = Left justified
bit 6 VCFG: Voltage Reference bit
1 = V
REF pin
0 = V
DD
bit 5-4 Unimplemented: Read as ‘0’
bit 3-2 CHS1:CHS0: Analog Channel Select bits
00 = Channel 00 (AN0)
01 = Channel 01 (AN1)
10 = Channel 02 (AN2)
11 = Channel 03 (AN3)
bit 1 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
bit 0 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
