I am NOT familiar with the chip you are using, but just yesterday I was near to pulling out my few remaining hairs before realizing that I had not set my TRIS registers to output. Is this necessary on the 18LF66K80?

Try adding this:

Then check the warnings during compile. It will tell you how to make all pins digital.

You set port D to digital but I see nothing for port A.
