Wait Control; Read Strobe (Rd) Timing - Renesas H8SX/1650 Hardware Manual

6.9.7

Wait Control

In the data cycle of the address/data multiplexed I/O interface, 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,
see section 6.6.4, Wait Control.
Wait control settings do not affect the address cycles.
6.9.8

Read Strobe (RD) Timing

In the address/data multiplexed I/O interface, the read strobe timing of data cycles can be modified
in the same way as in basic bus interface. For details, see section 6.6.5, Read Strobe (RD) Timing.
Figure 6.31 shows an example when the read strobe timing is modified.
