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.
