Notes
26. CE is internal signal. CE = LOW if CE0 = LOW and CE1 = HIGH. For a single Read operation, CE only needs to be asserted once at the rising edge of the CLK and
can be deasserted after that. Data is out after the following CLK edge and is three-stated after the next CLK edge.
27. OE is asynchronously controlled; all other inputs (excluding MRST and JTAG) are synchronous to the rising clock edge.
28. ADS = CNTEN = LOW, and MRST = CNTRST = CNT/MSK = HIGH.
29. The output is disabled (high-impedance state) by CE = VIH following the next rising edge of the clock.
30. Addresses do not have to be accessed sequentially since ADS = CNTEN = VIL with CNT/MSK = VIH constantly loads the address on the rising edge of the CLK.
Numbers are for reference only.
