Section 6 Bus Controller (BSC)
6.6.8
In the address/data multiplexed I/O interface, extension cycles can be inserted before and after the
data cycle. For details, see section 6.5.6, Extension of Chip Select (CS) Assertion Period. Figure
6.31 shows an example of the timing when the chip select assertion period is extended in the data
cycle.
