Rams,
If you have a question, word it to be clear and easily understood.

PIC have code protect option to prevent software pirates from making
illegal copies of the original software author's code.

The software inside a programmed PIC has been put there to give the PIC
instructions on what to do, how to do it, when to do it, and what to do
it with.

This software takes time to write, experience to do well, and equipment
to transfer the program into the PIC, therefore the programmer usually
does not want to give the program away for nothing.

Your question does not make clear wether the PC is there to pirate code
from the PIC, or to connect to the PIC as part of an application
programme.
