Legend:

R = Readable bit

u = Bit is unchanged

‘1’ = Bit is set

W = Writable bit

x = Bit is unknown

‘0’ = Bit is cleared

U = Unimplemented bit, read as ‘0’

-n/n = Value at POR and BOR/Value at all other Resets

bit 3-2

bit 1-0

ADFM: ADC Result Format Select bit

1 = Right justified. Six Most Significant bits of ADRESH are set to ‘0’ when the conversion result is

loaded.

0 = Left justified. Six Least Significant bits of ADRESL are set to ‘0’ when the conversion result is

loaded.

ADCS<2:0>: ADC Conversion Clock Select bits

000 = FOSC/2

001 = FOSC/8

010 = FOSC/32

011 = FRC (clock supplied from an internal RC oscillator)

100 = FOSC/4

101 = FOSC/16

110 = FOSC/64

111 = FRC (clock supplied from an internal RC oscillator)

Unimplemented: Read as ‘0’

ADPREF<1:0>: ADC Positive Voltage Reference Configuration bits

00 = VRPOS is connected to VDD

01 = Reserved

10 = VRPOS is connected to external VREF+ pin(1)

11 = Reserved

Note 1: When selecting the VREF+ pin as the source of the positive reference, be aware that a minimum voltage

specification exists. See Section 28.0 “Electrical Specifications” for details.
