Design Tips
Question 1:
Answer 1:
You may be getting stuck in an infinite loop with the comparator interrupt service routine if you
did not follow the proper sequence to clear the CMIF flag bit. First you must read the CMCON
register, and then you can clear the CMIF flag bit.
My program appears to lock up.
