NOTES:
1. When tSKEW1 minimum specification, tFRL (maximum) = tCLK + tSKEW1. When tSKEW1 < minimum specification, tFRL (maximum) = either 2 * tCLK + tSKEW1, or tCLK + tSKEW1. The
Latency Timing apply only at the Empty Boundary (
EF = LOW).
2. Select this mode by setting (
FL, RXI, WXI) = (0,0,0), (0,1,1), (1,0,0) or (1,1,1) during Reset.
NOTES:
1. tSKEW1 is the minimum time between a rising RCLK edge and a rising WCLK edge to guarantee that
FF will go HIGH during the current clock cycle. If the time between the rising edge
of RCLK and the rising edge of WCLK is less than tSKEW1, then
FF may not change state until the next WCLK edge.
2. Select this mode by setting (
FL, RXI, WXI) = (0,0,0), (0,1,1), (1,0,0) or (1,1,1) during Reset.
