Figure 5. Waveform for 2.0 Cycle Read Latency
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. The third NOP cycle between read to write transition is not necessary for correct device operation when Read Latency = 2.0 cycles; however at high frequency
operation, it may be required to avoid bus contention.
