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
CHS1:CHS0: Analog Channel Select bits
00 = Channel 00 (AN0)
01 = Channel 01 (AN1)
10 = Channel 02 (AN2)
11 = 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
Legend:
R = Readable bit
- n = Value at POR
ADFM
R/W-0
This bit is automatically cleared by hardware when the A/D conversion has completed.
