Just when you think you are getting on top of the new chips and what appears to be a new programming algorithm for each, you spot the 16F7x7 series. Example: the BOREN and BORSEN bits. These give 4 options to set the BOR function, (11, 10, 01, 00), but each bit is in seperate FUSE registers. I'm sure Microchip is trying to discourage third party programmers. Oh well, back to the drawing board :-( regards Tony -- http://www.piclist.com#nomail Going offline? Don't AutoReply us! email listserv@mitvma.mit.edu with SET PICList DIGEST in the body
