 		 #95577 - a question based on a guess
Responding to: ???'s previous message
In one my project my optoisolator was damaged and the output was in this range of signal,so mcu couldn't realize it and it was stoped when it was reading appropriate pin
a question based on a guess: are you using a pin both for memory access and I/O?. I can see no other way (besides awfully bad programming such as waiting for a pin to go high without a timeout) for a bad input signal to stop a program.
