Notes

27.Q00 refers to output from address A0. Q01 refers to output from the next internal burst address following A0, that is, A0 + 1.

28.Outputs are disabled (High-Z) one clock cycle after a NOP.

29.In this example, if address A4 = A3, then data Q40 = D30 and Q41 = D31. Write data is forwarded immediately as read results. This note applies to the whole diagram.
