  *Probably* not, but there's no reason to do it and it conflicts with
the prime objective of embedded programming; to use all the pins to best
advantage.

  If you wish to use RB0 as interrupt, fine.  What's good about the PIC
is that when you need an output, you TRIS that same pin into an output,
and TRIS it back to an input when you're finished.

  You will find the code *much* simpler to manage that way.
