Because you pretty much said you read everything except the data sheet, like you weren't aware of it or couldn't get hold of it. I thought I was giving you useful information that the data sheet was both necessary and sufficient to solve your problem. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
