    Register Definition
    The KBI includes three registers:
    An 8-bit pin status and control register
    An 8-bit pin enable register
    An 8-bit edge select register
    Refer to the direct-page register summary in Chapter 4, “Memory,” for the absolute address assignments
    for all KBI registers. This section refers to registers and control bits only by their names.
    The KBI registers are summarized in Table 7-2.
    7.3.1
    KBI Status and Control Register (KBISC)
    KBISC contains the status flag and control bits, which are used to configure the KBI.

    Field
    Description

    KBF
    Keyboard Interrupt Flag — KBF indicates that a keyboard interrupt is detected. Writes have no effect on KBF.
    0 No keyboard interrupt detected.
    1 Keyboard interrupt detected.
    2
    KBACK
    Keyboard Acknowledge — Writing a 1 to KBACK is part of the flag-clearing mechanism. KBACK always reads
    as 0.
