Writes to PORTE are actually written to corresponding LATE register. Reads from PORTE register is
return of actual I/O pin values.
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 PIC16F1933/1936/1938/PIC16LF1933/1936/1938. Read as ‘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
Unimplemented: Read as ‘0’
LATE<3:0>: PORTE Output Latch Value bits
