#186491 - AT89S8253 SerProgEn Fuse
I have an AT89S8253 that I would like to erase. However, I think the firm that programmed it cleared the SerProgEn fuse on it, which would prohibit my AT89ISP cable from being able to do it. Does anyone know of any parallel programmers that will allow me to erase the chip and reset the SerProgEn fuse to allow future programming via the ISP programmer?
