Figure 7. Read Cycle Timing with Single Register-Buffered EF (IDT Standard Mode)
NOTES:
1. tSKEW1 is the minimum time between a rising WCLK edge and a rising RCLK edge to guarantee that
EF will go HIGH during the current clock cycle. If the time between the rising edge
of WCLK and the rising edge of RCLK is less than tSKEW1, then
EF may not change state until the next RCLK 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.

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
applies only at the Empty Boundary (
EF = LOW).
2. The first word is available the cycle after
EF goes HIGH, always.
3. Select this mode by setting (
FL, RXI, WXI) = (0,0,0), (0,1,1), (1,0,0) or (1,1,1) during Reset.
