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 7-3
bit 2-0
Unimplemented: Read as ‘0’
ANSE<2:0>: Analog Select between Analog or Digital Function on Pins RE<2:0>, respectively
0 = Digital I/O. Pin is assigned to port or Digital special function.
1 = 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.
2: ANSELE register is not implemented on the PIC16F722/723/726/PIC16LF722/723/726. Read as ‘0’

x = unknown, u = unchanged, – = unimplemented locations read as ‘0’. Shaded cells are not used by PORTE
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.
