1. NOP commands are shown for ease of illustration; other commands may be valid at these times.
2. The BL8 setting is activated by either MR0[1, 0] = 0, 0 or MR0[0, 1] = 0, 1 and A12 = 1 during READ command at T0.
3. DO n = data-out from column n.
4. BL8, RL = 5 (AL = 0, CL = 5).
5. Output timings are referenced to V
6.
7. Early data transitions may not always happen at the same DQ. Data transitions of a DQ can vary (either early or late)

within a burst.
DQSQ defines the skew between DQS, DQS# to data and does not define DQS, DQS# to clock.
