26. Q00 refers to output from address A0. Q01 refers to output from the next internal burst address following A0, that is, A0+1.
27. Outputs are disabled (High-Z) one clock cycle after a NOP.
28. In this example, if address A0 = A1, then data Q00 = D10 and Q01 = D11. Write data is forwarded immediately as read results. This note applies to the whole diagram.
