Is there a document that describes the values of memory between locations 0x2000 and 0x2007 on a mid-range PIC? After scanning the mid-range data book, I've developed a map that looks like this. 0x2000 - ID Word 0x2001 - ID Word 0x2002 - ID Word 0x2003 - ID Word 0x2004 - ??? 0x2005 - ??? 0x2006 - ??? 0x2007 - Configuration Word What are 0x2004 through 0x2006 used for? -Mike -- http://www.piclist.com hint: The PICList is archived three different ways.
