16 years agoThanks again FvM,
We observed that, during programming, only write cycles are done (no polling) and write cycles are done with short time intervals measured (with oscilloscope) between 10 us and 57 us; those values seem shorter than the conventional word programming times (200 us reported on Intel/Numonyx P30 data sheet). The data sheet reports that the flash chip has a small buffer for write operations so the option bit (that are a small) can be saved in the buffer while most part of the data are lost due to, most likely, a buffer overflow having insufficient pauses between writes. But I am not shure I have understood correctly your suggestion. sincerely, gabrigob
