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.
x = unknown, u = unchanged, – = unimplemented locations read as ‘0’. Shaded cells are not used by PORTE.
Applies to ECCP modules only.
ANSE<7:0> : Analog Select between Analog or Digital Function on Pins RE<7:0>, respectively
0 = Digital I/O. Pin is assigned to port or digital special function.
1 = Analog input. Pin is assigned as analog input
