Unimplemented: Read as ‘0’.

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

ANS3:ANS0: Analog Select bits

(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. The corresponding TRISIO bit must be set

to Input mode in order to allow external control of the voltage on the pin.

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
