1. AL = 0, RL = 8.
2. DO n (or b) = data-out from column n (or column b).
3. Seven subsequent elements of data-out appear in the programmed order following DO n.
4. Seven subsequent elements of data-out appear in the programmed order following DO b.
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] = 00 or MR0[1:0] = 01 and A12 = 1 during the READ command at
3. DO n = data-out from column, DI b = data-in for column b.
