Hi!

I have a port on my 16f877, PORTA.
All pins set as output. RA4 and RA5 are controlled from another part of my
application but I wanna write a nybble to RA0->RA3, in C, without touching
RA4 and RA5.

I tried reading, anding, oring but nothing worked. I had to do a switch and
set RA0->RA3 bit by bit. Do I need a shadow reg. for RA4 and RA5?

Is there an easier way?
