>That's why I suggested looking at DS00734A. This is a source of confusion in itself. Although the document number is DS00734x where x is the document revision, the title is AN734, and the electronic form of the document on the microchip website is 00734x.pdf, without either DS or AN as a prefix. This is why people have problems searching the Microchip site for documents. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
