signals of multiple devices. Status flags can be detected from any one
device. The exceptions are the EF and FF functions in IDT Standard mode
and the IR and OR functions in FWFT mode. Because of variations in skew
between RCLK and WCLK, it is possible for EF/FF deassertion and IR/OR
assertion to vary by one cycle between FIFOs. In IDT Standard mode, such
problems can be avoided by creating composite flags, that is, ANDing EF
NOTES:
1. Use an AND gate in IDT Standard mode, an OR gate in FWFT mode.
2. Do not connect any output control signals directly together.
3. FIFO #1 and FIFO #2 must be the same depth, but may be different word widths.

72V2113 devices. If x18 Input or x18 Output bus Width is selected, D
each device form a 36-bit wide input bus and Q
a 36-bit wide output bus. If both x9 Input and x9 Output bus Widths are selected,
