NOTE A: A write cycle or a read-modify-write cycle can be mixed with the read cycles as long as the write and read-modify-write timing
specifications are not violated and the proper state of DSF is latched on the falling edge of RAS and CASx to select the desired write
mode (normal, block write, etc.).
