AT89S51 interface MT8888C

Eric Yeow

Hi friends....

Now I have a software question...

I want interafce MT8888C, which is compatible with fast versions (16MHZ ) of the 80C51, with AT89C51 using 12MHZ clock.

How can I realize this control by inserting cycles?

I only get a 12MHZ emulator is the main reason for me to chose 12MHZ clock.

Thank you for your generous suggestions....

    Hi
    You wouldn't have any problem in interfacing MT8888C with your emulator(12MHz)since MT8888C operates according to /RD or /WR signals.
    When the datasheet notes that the IC is compatible with fast versions it means the timings of the /RD & /WR signals can be fast(in otherwords its bus can operate at higher rates).

    Best Regards,
    A.E.
