fill operation in the event of a cache miss, the missed data is read first, then 16-byte boundary data
including the missed data is read in wraparound mode.
Single Read: Figure 12.15 shows the timing when a single address read is performed. As the burst
length is set to 1 in synchronous DRAM burst read/single write mode, only the required data is
output. Consequently, no unnecessary bus cycles are generated even when a cache-through area is
accessed.
