Section 12 Bus State Controller (BSC)
Single Read: A read access ends in one cycle when data exists in non-cacheable region and the
data bus width is larger than or equal to access size. As the burst length is set to 1 in synchronous
DRAM burst read/single write mode, only the required data is output.
Figure 12.20 shows the single read basic timing.
