AC CHARACTERISTICS)
Notes:
1. RDY active with data (A18 = 0 in the Configuration Register).
2. RDY active one clock cycle before data (A18 = 1 in the Configuration Register).
3. Cxx indicates the clock that triggers Dxx on the outputs; for example, C60 triggers D60. Figure shows the device not crossing
4. If the starting address latched in is either 3Eh or 3Fh (or some 64 multiple of either), there is no additional 2 cycle latency at
