Hi

Hi. I was just wondering if it is possible to have my software store data in it's own program memory?

For example:

I am using the 89C4051 with 4kb flash memory. Now my code is 3kb big. That leaves 1kb of unused program memory. The 89C4051 doesn't have any onboard EEPROM. Thus I cannot store any data without external components.

So the question: Is it possible to use the last 1kb as a psuedo-EEPROM to store data? I would prefer if this needed no external components. However, for experiment purposes if external components are needed I would love to see how it can be done.

I would imagine it cannot to be done normally, but would there be a way to trick the controller into doing it?

Thanks
