NOTES: 1. BL8, RL = 6 (CL = 6, AL = 0).
2. Dout n (or b) = data-out from column n (or column b).
3. NOP commands are shown for ease of illustration; other commands may be valid at these times.
4. BL8 setting activated by either MR0 A[1:0] = 00 or MR0 A[1:0] = 01 and A12 = 1 during READ commands at T0 and T4.
