Notes:

17. When tSKEW1 > minimum specification, tFRL (maximum) = tCLK + tSKEW2. When tSKEW1 < minimum specification, tFRL (maximum) = either 2*tCLK + tSKEW1 or tCLK + tSKEW1.

The Latency Timing applies only at the Empty Boundary (EF = LOW).

18. The first word is available the cycle after EF goes HIGH, always.
