Switching Waveforms
[28, 29, 30]
Notes:
28.Q00 refers to output from address A0. Q01 refers to output from the next internal burst address following A0, i.e., A0 + 1.
29.Output are disabled (High-Z) one clock cycle after a NOP.
30.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
