I'm sure that will give you a pretty good idea. Obviously having caps and a crystal connected to these pins will raise the capacitance of the data and clock lines which may cause timing problems. If you can say, I'm curious why you have a crystal oscillator on RB6/7! -- Best regards Tony mICros http://www.bubblesoftonline.com mailto:sales@bubblesoftonline.com -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
