Timing Waveform of Read Cycle for Pipelined Operation
(FT/PIPE
NOTES:
1. OE is asynchronously controlled; all other inputs depicted in the above waveforms are synchronous to the rising clock edge.
2. ADS = V
3. The output is disabled (High-Impedance state) by CE
4. Addresses do not have to be accessed sequentially since ADS = V
5. If BE
6. "x" denotes Left or Right port. The diagram is with respect to that port.
