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.
OPTIONAL CONFIGURATIONS
WIDTH EXPANSION CONFIGURATION
Word width may be increased simply by connecting together the control
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
of every FIFO, and separately ANDing
FF of every FIFO. In FWFT mode,
