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

= FOSC/2

001

= FOSC/8

010

= FOSC/32

x11

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

100

= FOSC/4

101

= FOSC/16

110

= FOSC/64

bit 3-0

ANS<3:0>: Analog Select bits

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

= Analog input. Pin is assigned as analog input(1).

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

Note

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.
