Notes:
1. DI n (or b) = data-in for column n (or column b).
2. Seven subsequent elements of data-in are applied in the programmed order following DO n.
3. Each WRITE command may be to any bank.
4. Shown for WL = 7 (CWL = 7, AL = 0).

Notes:

WTR controls the WRITE-to-READ delay to the same device and starts with the first rising clock edge after the last
write data shown at T9.
3. The BL8 setting is activated by either MR0[1:0] = 00 or MR0[1:0] = 01 and MR0[12] = 1 during the WRITE command
at T0. The READ command at Ta0 can be either BC4 or BL8, depending on MR0[1:0] and the A12 status at Ta0.
4. DI n = data-in for column n.
5. RL = 5 (AL = 0, CL = 5), WL = 5 (AL = 0, CWL = 5).
