Re: How does Floating MOSFETs in a PROM actually create a group of instructions?

How does the Floating MOSFET array in a PROM turn into a group of
instructions? I mean, you burn the "fuses" allowing for either a 1 or a
0 on each MOSFET, but how does this in turn, turn into a, do this if
this does that. Whats actually occuring?

All uP instructions are nothing more than data. The processor just
fetches bytes at the instruction pointer location and interprets them as
instructions. Same as reading executable instructions from RAM, but with
microcontrollers the program doesn't change. So its just burned into a
PROM (or an EPROM, or other non-volatile memory).
