Section 6 Bus Controller (BSC)
Figure 6.20 shows an example of the timing when the CS assertion period is extended in basic bus
3-state access space.
Both extension state T
basic bus cycle, or only one of these, can be specified for individual areas. Insertion or non-
insertion can be specified for the T
register, and for the T
