Hi, So I have this strange issue with 16f628a. If I connect RB4 it to +5V, everything hangs, all ports go to 0. It does that no matter whether it is set to input or output. My program is very complex, so to make sure that it is not because of a logical mistake, I tried with this simple program instead - http://pastebin.com/mDNvixWv . The problem stays. Is there some sort of trick for this port/controller that I don't know of or am I mistaking somewhere?
