I know that on a Tiny13V, if you disable the reset fuse, you can no longer do serial low voltage programming, which it mentions in the datasheet.
I am getting ready to start a project using a MEGA48V and am going to need every I/O. Therefore, I will be programming this fuse. I don't see any thing in the data sheet that says that once programmed, it required HV programming to unprogram it.
Does anybody know if I can program and unprogram this fuse using low voltage serial ISP programming?>
