Notes: 1. BC4, RL = 5 (CL = 5, AL = 0), WL = 5 (CWL = 5, AL = 0).
2. Dout n = data-out from column n, Din b= data-in from column b.
3. NOP commands are shown for ease of illustration; other commands may be valid at these times.
4. BC4 setting activated by MR0 bit [A1, A0] = [0, 1] and A12 = 0 during READ command at T0 and WRIT command T4.
