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 7-3

Unimplemented: Read as ‘0’

bit 2-0

ANSE<2:0>: Analog Select between Analog or Digital Function on Pins RE<2:0>, respectively

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

= Analog input. Pin is assigned as analog input(1). Digital Input buffer disabled.

Note 1:

When setting a pin to an analog input, the corresponding TRIS bit must be set to Input mode in order to

allow external control of the voltage on the pin.

ANSELE register is not implemented on the PIC16F722/723/726/PIC16LF722/723/726. Read as ‘0’

Note

These registers are not implemented on the PIC16F722/723/726/PIC16LF722/723/726 devices, read as ‘0’.

This bit is always ‘1’ as RE3 is input only.
