Notes

31.Q00 refers to output from address A0. Q01 refers to output from the next internal burst address following A0, i.e., A0+1.

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

33.In this example, if address A2 = A1, then data Q20 = D10 and Q21 = D11. Write data is forwarded immediately as read results. This note applies to the whole diagram.
