NOTES:

1. Only applies for a clock edge that does a FIFO read.

2. Requirement to count the clock edge as one of at least four needed to reset a FIFO.

3. Skew time is not a timing constraint for proper device operation and is only included to illustrate the timing relationship between CLKA cycle and CLKB

cycle.
