Just want to verify if I am reading correctly
On the ATmega8, by programming a fuse the RESET pin can be used as PC6
Since the serial and parallel programing modes us the RESET, if this fuse is programmed, the chip can only be reprogrammed by the boot loader.
Further, since the fuse bit can not be written by the boot loader, once it is programmed, there is no way to undo it.
Is this correct, or have I missed something :?:
