hi,

I use isp downloading.
I have problem with ISP fuse bit. I already disable the ISP programming fuse, so I can not programming the chip via ISP. How to clear the fuse bit to default state. Datasheet says: The ISP Enable Fuse must be enabled before entering ISP mode. By other words is you disable ISP mode then there is no way to invoke this mode once again till you enable the mode with parallel programming. Regards, Oleg |
