OR
OR Flag Timing and First Word Fall Through when FIFO is Empty (FWFT 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 after one RCLK cycle plus tREF. If the time between the rising edge
of WCLK and the rising edge of RCLK is less than tSKEW1. then the
EF deassertion may be delayed an extra RCLK cycle.
2.
LD = HIGH
3. Select this mode by setting (
FL, RXI, WXI) = (0,1,0) or (1,1,0) during Reset.

EF (IDT Standard Timing)
NOTES:
1. tSKEW1 is the minimum time between a rising WCLK edge and a rising RCLK edge for
OR to go HIGH during the current cycle. If the time between the rising edge of WLCK and the rising
edge of RCLK is less than tSKEW1, then the
OR deassertion may be delayed one extra RCLK cycle.
2.
LD = HIGH, OE = LOW
3. Select this mode by setting (
FL, RXI, WXI) = (0,0,1) or (1,0,1) during Reset.
