These FIFOs are in a single Device Configuration when the First Load (FL),
Write Expansion In (WXI) and Read Expansion In (RXI) control inputs are
configured as (FL, RXI, WXI = (0,0,0), (0,0,1), (0,1,0), (1,0,0), (1,0,1) or
(1,1,0) during reset (Figure 28).

Synchronous FIFO Memory Used in a Width Expansion Configuration
WIDTH EXPANSION CONFIGURATION
Word width may be increased simply by connecting together the control
signalsofmultipledevices. Statusflagscanbedetectedfromanyonedevice.

BecauseofvariationsinskewbetweenRCLKandWCLK,itispossibleforflag
assertion and deassertion to vary by one cycle between FIFOs. To avoid
