Microchip doesn't make much effort to give us the information we need. They leave beta testing to the customers. You shouldn't have to track down and study multiple documents to figure out which chip revision you have and which errata applies to it. None of us have time for that. No one but you and a couple of others on this list who design programmers should ever have any reason to read programming specifications. Microchip is spread way too thin, and there are too many bugs in their chips. Cheerful regards, Bob -- http://www.fastmail.fm - mmm...
