The relevant specs that I know of are the min/max Vdd limits during operation. I don't recall the data sheet telling me (nor should it) how to produce this voltage, only what it needs to be. > Are you just trying to be difficult? I thought it was a legitimate question that deserved a straight answer. If you're going to be uppity, you need to be right first. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
