Section 6 Bus Controller
Example of Wait State Control Settings: A reset initializes ASTCR and WCER to H'FF and
WCR to H'F3, selecting programmable wait mode and three wait states for all areas. Software can
select other wait modes for individual areas by modifying the ASTCR, WCER, and WCR settings.
Figure 6.16 shows an example of wait mode settings.
