An interesting aside to this saga. Jeff from Melabs emailed me back about this quirk. This is important for anyone using Analog inputs with digital outputs. When the uP is commanded to change a bit, it reads, modify,writes the entire port. Since Analog bits are read as zero, when the port is rewritten, any Analog bit will be written as a zero. Even if it was used as a digital high output,as was in my case. Verrrry interesting!
