— = 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.
