Did I fry my PIC?

I'm using a PIC18LF2525 and accidentally hooked up +9V to pin B0. Now I can't get B0 to do anything. Even a simple

Code:

output_high(PIN_B0);

doesn't work, but all other pins seem to be working fine. Should I read my PIC its last rites? Is it in a better place now?

At the very least you have trashed some or all of port B. Probably best to swich to a new chip and be carefull.

Put a new chip in and everything works now. Butterfingers beware I suppose.
