Hello, This is probably becoming a legacy topic. I hope there's someone out there who can assist. According to the 68HC11 reference manual, Port A PA3-6 can be general purpose outputs, or driven by timer output compare functions. If one disables the latter then it should simply be a matter ...Strange behaviour, I/O port, 68HC11
