bit 7 bit 0

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 Unimplemented: Read as ‘0’

bit 6-4 ADCS<2:0>: A/D Conversion Clock Select bits

000 = F

OSC/2

001 = F

OSC/8

010 = F

OSC/32

x11 = F

RC (clock derived from a dedicated internal oscillator = 500 kHz max)

100 = F

OSC/4

101 = F

OSC/16

110 = F

OSC/64

bit 3-0 ANS<3:0>: Analog Select bits

Analog select between analog or digital function on pins AN<3:0>, respectively.

1 = Analog input. Pin is assigned as analog input

(1)

0 = Digital I/O. Pin is assigned to port or special function.

Note 1: Setting a pin to an analog input automatically disables the digital input circuitry, weak pull-ups and interrupt-on-change,

if available. The corresponding TRIS bit must be set to Input mode in order to allow external control of the voltage on

the pin.
