That's probably why nobody had noticed this discrepancy in the manual before. Why do you care about the power up state of FSR0? ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
