As many others have said - anything which can program
a PIC can ERASE the chip, and doing so will reset the
code protect bit. =20

Now, if you are trying to turn code protection OFF
without erasing the code which is in there, you have a
problem.  That is exactly what the code protect bit
is in there to prevent.

Please be more specific as to what and why.
