— = unimplemented location, read as ‘0’. Shaded cells are not used by PORTA.
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 PORTA.

Unimplemented: Read as ‘0’
ANSA5: Analog Select between Analog or Digital Function on pins RA<5>, 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’
ANSA<3:0>: Analog Select between Analog or Digital Function on pins RA<3:0>, respectively
0 = Digital I/O. Pin is assigned to port or digital special function.
