Microchip wouldn't have provided multiple power and ground pins unless they were needed. Yes, they are connected internally with a teeny tiny little bond wire, but that's not the same as being shorted with a decent copper trace externally. I always make sure these pins are connected to each other with as small a loop as possible. ******************************************************************** Olin Lathrop, embedded systems consultant in Littleton Massachusetts (978) 742-9014, olin@embedinc.com, http://www.embedinc.com -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
