Section 9 Bus State Controller (BSC)
(4)
A read access ends in one cycle when data exists in a cache-disabled space and the data bus width
is larger than or equal to the access size. As the SDRAM is set to the burst read with the burst
length 1, only the required data is output. A read access that ends in one cycle is called single read.
Figure 9.19 shows the single read basic timing.
