Of course, you can not "see" anything inside of the PIC
using normal interfaces (that is, not using a "programmer"
or "debugger") without the help from some code running
as part of the PIC application.

You can not "make a register available to the UART".

The code could (on request) take the value from a register
and write it out to the outside using teh UART (to InTouch
or whatever are at the other end of the "line").

I've no idea what has to be done in InTuch...
