Neil,

You can reprogram flash pics even they are code protected.
It will first erase the program memory to make it blank
Then it becomes unprotected part to allow you to reprogram

I read in some places (datasheets, etc) that code protection is a great
feature, etc and what is does, etc.  Great!  However, on other sites,
I've read that I should absolutely not use it cause the chip will be
forever un-reusable, even if it's erased.  Huh???

So what's the real (and lastest) deal here?  Is there a problem with a
specific PIC or series of PIC's?  Is a a non-reliable feature for all
PIC's?
I'm using the PIC16F84A and PIC16F872 for now, so I mostly concerned
about these for now.

Cheers,
-Neil.
