Arg You can save yourself all these little troubles by using my PIC 18 interrupt template QQQ_INTR18.ASPIC at http://www.embedinc.com/pic. You configure it at the top for single or high/low interrupt priorities and assembly time magic takes care of the rest. You only have to insert your application-specific interrupt code. ****************************************************************** Embed Inc, Littleton Massachusetts, (978) 742-9014. #1 PIC consultant in 2004 program year. http://www.embedinc.com/products -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
