Hi, INT has no connection with Timer0. Timer0 in count mode is clocked by transistions on RA4 / T0CKI. But you can make RA4 behave like INT by setting Timer0 to FF and clocking it to generate a T0 overflow interrupt. Then reload Timer0 with FF for the next one (Don't forget RA4 pull-up and pre-scaler assignment) -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
