Section 13 Bus State Controller (BSC)
Byte specification is performed by DQM0 to DQM7. A read/write is performed for the byte for
which the corresponding DQM signal is low. When the bus width is 64 bits, in big-endian mode
DQM7 specifies an access to address 8n, and DQM0 specifies an access to address 8n + 7. In
little-endian mode, DQM7 specifies an access to address 8n + 7, and DQM0 specifies an access to
address 8n.
Figures 13.26 and 13.27 show examples of the connection of 16M × 16-bit synchronous DRAMs.
