This chip has inputs designated as ANxx. This is clear it is an analogue input.
It also has inputs Axx . – I am under the impression this is also analogue.
It also has ADxx – I am under the impression this is also analogue.
However, I cannot assign Axx And ADxxx to the potentiometer.
What type of inputs are these.

Hi

ANxx such as Port A1 = Analogue Input

Axx such as Port H2 = Address bit for external memory

ADxx such as Port E3 = Address / data bit for external memory

Chapter 10 of the 18F8520 datasheet explains in detail and of course the pins have other functions too such as Digital I/O.

Thank you.
