Legend:
R = Readable bit
u = Bit is unchanged
‘1’ = Bit is set
W = Writable bit
x = Bit is unknown
‘0’ = Bit is cleared
U = Unimplemented bit, read as ‘0’
-n/n = Value at POR and BOR/Value at all other Resets
bit 7-4
bit 3-0
Unimplemented: Read as ‘0’
LATE<3:0>: PORTE Output Latch Value bits⁽¹⁾
Note 1: Writes to PORTE are actually written to corresponding LATE register. Reads from PORTE register is
return of actual I/O pin values.
2: LATE register is not implemented on the PIC16(L)F1938. Read as ‘0’

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 PIC16(L)F1938. Read as ‘0’
