Note 1-1: tw (cycle) and trec (CTRL) are necessary when accessing the FIFO.
Note 1-2: The control signal when writing data is a combination of CS_N, WR1_N, and WR0_N.
Note 1-3: The control signal when reading data is a combination of CS_N and RD_N.
Note 1-4: RD_N, WR0_N and WR1_N should not be timed to fall at the same time that CS_N is rising. Similarly,
CS_N should not be timed to fall at the same timing that WR0_N and WR1_N are rising. In the instances noted
above, an interval of at least 10 ns must be left open.
