I am looking hard for an _official_ app note showing how it is done, exactly. I mean, code snippet, targeted at new "enhanced" arch pics, perhap= s 10F320 which is what I am dealing with now. I know how to do it, but too much depends on small omissions or missteps. If there is such an app note, then I cannot find it! Can someone please point me right? Only thing I foun= d is "Emulating Data EEPROM for PIC18 and PIC24 ..." which is not directly an= d _specifically_ relevant to the new 'enhanced' pics. thanks, Peter --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
