bit 0

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

bit 7

bit 6

bit 5

bit 4-2

bit 1

bit 0

ADFM: A/D Conversion Result Format Select bit

1 = Right justified

0 = Left justified

VCFG: Voltage Reference bit

1 = VREF pin

0 = VDD

Unimplemented: Read as ‘0’

CHS<2:0>: Analog Channel Select bits

000 = Channel 00 (AN0)

001 = Channel 01 (AN1)

010 = Channel 02 (AN2)

011 = Channel 03 (AN3)

100 = CVREF

101 = 0.6V Reference

110 = 1.2V Reference

111 = Reserved. Do not use.

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: ADC Enable bit

1 = ADC is enabled

0 = ADC is disabled and consumes no operating current

Note 1: When the CHS<2:0> bits change to select the 1.2V or 0.6V reference, the reference output voltage will

have a transient. If the Comparator module uses this 0.6V reference voltage, the comparator output may

momentarily change state due to the transient.
