You don't tell what the problem is, so it's a bit hard to tell what you're asking for... The best way is to read whatever the datasheet has to tell *first*, then ask about the unclear points. That makes is much easier for everyone, and we don't have to repeat the parts of the datasheet that you actualy *did* understand... :-) Best Regards, Jan-Erik. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
