Notes:
25. Q00 refers to output from address A0. Q01 refers to output from the next internal burst address following A0 i.e., A0+1.
26. Outputs are disabled (High-Z) one clock cycle after a NOP.
27. 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.
