  • hi,
    no way to discuss it. Use port0: 4 bits as output and 4 bits as input (do not forget to add pull-up resistors for last ones). If you search for keyboard management IC especialy then there are some x51 MCUs with such option, for example Atmel's
    AT89C51RB2/RC2 - they have built-in Keyboard Interrupt Interface.

    Good days!
