Configuring Port A, Pin 4 as a general I/O pin in the PIC18F442



Hello World,

I'm using the PIC18F442 and I can't seem to configure Pin 4 of Port A
to be a normal I/O Pin.

I've tried to disable the T0CON register that also has functionality
on that pin and I still can't use the pin as a general I/O pin.

I need it for a project and I have already made the PCB board so that
pin has to work. Can anyone help me?

Thanks a million.
