ADFM: A/D Result Formed Select bit

= Right justified

= Left justified

bit 6

VCFG: Voltage Reference bit

= VREF pin

= VDD

bit 5-4

Unimplemented: Read as ‘0’

bit 3-2

CHS<1:0>: Analog Channel Select bits

= Channel 00 (AN0)

= Channel 01 (AN1)

= Channel 02 (AN2)

= Channel 03 (AN3)

bit 1

GO/DONE: A/D Conversion Status bit

= 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.

= A/D conversion completed/not in progress

bit 0

ADON: A/D Conversion Status bit

= A/D converter module is operating

= A/D converter is shut off and consumes no operating current

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
