Code Protection

[Del Tapparo]

Simple question: If I turn on code protection for the program memory of a PIC, this will obviously not allow program memory to be read. Can I still write to it? (e.g. If I want to update the software in the future.)

I would assume so, but I don't want to potentially waste a chip to find out.

With a flash-based part yes. Just erase it before re-programming it.

With an OTP no. Once programmed, it's a done deal.
