How about a cap on one of the MCLR lines to guarantee one processor starts before the other? Some startup protocol using the UART lines between the processors can then be used so that each one knows if it's first or second. Just watch the max MCLR rise time. You may need something a little more sophisticated than a cap to get the delay and minimum rise time. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com#nomail Going offline?
