    80C51XA
    The Philips 80C51XA MCU family supports an 8-
    or 16-bit multiplexed bus that can have burst cy-
    cles. Address bits (A3-A0) are not multiplexed,
    while (A19-A4) are multiplexed with data bits
    (D15-D0) in 16-bit mode. In 8-bit mode, (A11-A4)
    are multiplexed with data bits (D7-D0).
    The 80C51XA can be configured to operate in
    eight-bit data mode (as shown in Figure
    24
    ).
    The 80C51XA improves bus throughput and per-
    formance by executing burst cycles for code fetch-
    es. In Burst Mode, address A19-A4 are latched
    internally by the PSD, while the 80C51XA changes
    the A3-A0 signals to fetch up to 16 bytes of code.
    The PSD access time is then measured from ad-
    dress A3-A0 valid to data in valid. The PSD bus
    timing requirement in Burst Mode is identical to the
    normal bus cycle, except the address setup and
    hold time with respect to Address Strobe (ALE/AS,
    PD0) does not apply.
