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 Format Select bit

1 = Right justified

0 = Left justified

bit 6

Unimplemented: Read as ‘0’

bit 5-3

ACQT<2:0>: A/D Acquisition Time Select bits

111 = 20 TAD

110 = 16 TAD

101 = 12 TAD

100 = 8 TAD

011 = 6 TAD

010 = 4 TAD

001 = 2 TAD

000 = 0 TAD(1)

bit 2-0

ADCS<2:0>: A/D Conversion Clock Select bits

111 = FRC (clock derived from A/D RC oscillator)(1)

110 = FOSC/64

101 = FOSC/16

100 = FOSC/4

011 = FRC (clock derived from A/D RC oscillator)(1)

010 = FOSC/32

001 = FOSC/8

000 = FOSC/2

Note 1:

If the A/D FRC clock source is selected, a delay of one TCY (instruction cycle) is added before the A/D

clock starts. This allows the SLEEP instruction to be executed before starting a conversion.
