hello everyone.
I am from china. Now I was in trouble with designning a interface with an old device controled by 8749, an old mcs48 series microcontroller. The chip is so old that any device i have now cannot read it. So what i can do is setting up a circuit to read it. But i had no idea of how to read the program from 8749. I cannot find it in the datasheet.
can anyone help me?
