In the data cycle, program wait insertion and pin wait insertion by the WAIT pin are enabled in the
same way as in the basic bus interface. For details, refer to section 6.5.4, Wait Control. Wait
control settings do not affect the address cycles.

In the address/data multiplexed I/O interface, the read strobe timing of data cycles can be modified
in the same way as in the basic bus interface. For details, refer to section 6.5.5, Read Strobe (RD)
Timing. Figure 6.30 shows an example when the read strobe timing is modified.
