But note that it is still the value loaded into the TMRH-buffer from the *last* loop that us used, so it's a "bug" just waiting to happen, so to speek. If you for some reason later on decides that you want different TMR0H values each loop, you'd had a very nasty bug there... :-) Jan-Erik. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
