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 6-3

bit 2-0

ADFM: A/D Result Format Select bit

1 = Right justified

0 = Left justified

ACQT<3:0>: A/D Acquisition Time Select bits

0000 = No delay (conversion starts immediately when GO/DONE is set)(1)

0001 = 2 TAD

0010 = 4 TAD

0011 = 6 TAD

0100 = 8 TAD

0101 = 10 TAD

0110 = 12 TAD

0111 = 16 TAD

1000 = 20 TAD

1001 = 24 TAD

1010 = 28 TAD

1011 = 32 TAD

1100 = 36 TAD

1101 = 40 TAD

1110 = 48 TAD

1111 = 64 TAD

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

000 = FOSC/2

001 = FOSC/8

010 = FOSC/32

011 = FRC/4

100 = FOSC/4

101 = FOSC/16

110 = FOSC/64

111 = FRC (Internal A/D RC Oscillator)

Note 1: If the A/D RC 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.
