    Clock Waveforms
    Valid in normal clock mode. In X2 mode XTAL2 signal must be changed to XTAL2 divided by
    two.
    Figure 11-14.
    Clock Waveforms
    This diagram indicates when signals are clocked internally. The time it takes the signals to prop-
    agate to the pins, however, ranges from 25 to 125 ns. This propagation delay is dependent on
    variables such as temperature and pin loading. Propagation also varies from output to output
    and component. Typically though (T
    A
    =25
    °
    C fully loaded) RD and WR propagation delays are
    approximately 50ns. The other signals are typically 85 ns. Propagation delays are incorporated
    in the AC specifications.
