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
