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

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.

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
