Jan your method worked like a charm. Was able to get the SerProgEn fuse re-enabled going by the recommended P3.3-P3.7 sequence and the parallel programming specification.
Now I seem to have another issue. I cannot get my AT89ISP software to write the fuse bits. I have my final revision of code and am about to distribute the pre-loaded chips. The software seems to write the lock bits fine, but if I try to disable the SerProgEn fuse, it doesn't do it. I uncheck it, it gives me the warning, in which I click OK, then I click the "Write" button. Only to find that the fuse bits are still the same. Anyone else experience this issue? |
