Notes: • For signal-to-signal timing, see Figure 21.7.8, "Read Timing (Relative to Read Pulse),"
and Figure 21.7.9, "Write Timing (Relative to Write Pulse)."
• When using the threshold switching function, the data input and WAIT# voltage levels are
determined with respect to the rated minimum and maximum values for VIH and VIL.
