    What exactly is your doubt here?

    Some 8051-derivates need some configuration (SFRs, etc) to control external memory access - is that it?
    If so, you need to state what chip you're using!

    Or do you mean how to design the hardware?
    That's in the so-called "bible", plus any specifics from the documentation for your particular chip.

    Otherwise, it's just a matter of using CODE and/or XDATA space - you can look that up in the C51 manual
