A write access ends in one cycle when data is written in a cache-disabled space and the data bus
width is larger than or equal to access size. As a single write or burst write with burst length 1 is
set in SDRAM, only the required data is output. The write access that ends in one cycle is called
single write. Figure 9.21 shows the single write basic timing.
