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  
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  
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 inter-  
rupt-on-change. The corresponding TRISIO bit must be set to Input mode in order to allow external control  
of the voltage on the pin.
