Read Cycle for Flow-Through Output (FT/PIPE = VIL)
[14, 15, 16, 17]
Read Cycle for Pipelined Operation (FT/PIPE = VIH)
[14, 15, 16, 17]
Notes:
14. OE is asynchronously controlled; all other inputs are synchronous to the rising clock edge.
15. ADS = VIL, CNTEN and CNTRST = VIH.
16. The output is disabled (high-impedance state) by CE0=VIH or CE1 = VIL following the next rising edge of the clock.
17. Addresses do not have to be accessed sequentially since ADS = VIL constantly loads the address on the rising edge of the CLK. Numbers are for reference only.
