Section 9 Bus Controller (BSC)
9.10.10 Controlling Byte and Word Accesses
When 16-bit bus DRAM is used, two CAS signals can be used to control byte and word accesses.
Figures 9.45 and 9.46 show control timing examples with use of two CAS signals (in big endian
format). Figure 9.47 shows an example of connection for control with two CAS signals.
