If the time between the rising edge of WCLK and the rising edge of RCLK is less than tSKEW2, then it is not guaranteed that EF will change state until the next following RCLK edge. 2. tFRL (First-Read Latency) is the minimum time between a rising WCLK edge and a rising RCLK edge to assure a correct readout of the first data word D0 in response to the next RCLK edge. Thus, tFRL = tCLK + tSKEW2. If tFRL is not met, D0 may be available either at tCLK + tSKEW2, or after one more clock cycle delay at 2 tCLK + tSKEW2. The First-Read Latency timing restrictions apply only when the FIFO has been empty (EF = LOW). 3. EF may be used to determine when the first data word D0 may be read. D0 always is available on the next cycle after EF has gone HIGH. LOW BOLD ITALIC = Enhanced Operating Mode. EF2 tREF tREF Figure 11.
