9.11.11 Controlling Byte and Word Accesses
When 16-bit bus SDRAM is used, byte and word accesses are performed through the control of
DQMLU and DQMLL.
Figures 9.69 and 9.70 show control timing examples of the DQM signals in the big endian format.
Figure 9.71 shows a connection example when the DQM signals are used for the byte and word
control.
