Notes

28. Q00 refers to output from address A0. Q01 refers to output from the next internal burst address following A0, that is, A0+1.
29. Outputs are disabled (High-Z) one clock cycle after a NOP.
30. In this example, if address A2 = A1, then data Q20 = D10, Q21 = D11, Q22 = D12, and Q23 = D13. Write data is forwarded immediately as read results. This note 

applies to the whole diagram.
