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 crossing a
