My copy of the english help file only shows topic headings on the left nothing on the right? Any Ideas. This is my first chip programer so I would not mind reading the help file. Specifically when I go to program a chip what does the LOCK Bit do? Through trial and error I have found that if LOCK Bit is checked when I run the Verify command it fails. If LOCK Bit is unchecked Verify passess and the chip works.
