OPERATIONAL MODES (cont’d)

Compound FIFO Expansion

A combination of word-width expansion and depth

cascading may be implemented easily by operating

groups of depth-cascaded FIFOs in parallel.

Bidirectional FIFO Operation

Bidirectional data buffering between two systems may

be implemented by operating LH540203 devices in par-

allel, but in opposite directions. The Data In inputs of each

LH540203 are tied to the corresponding Data Out outputs

of another LH540203, which is operating in the opposite

direction, to form a single bidirectional bus interface. Care

must be taken to assure that the appropriate read, write,

and flag signals are routed to each system. Both word-

width expansion and depth cascading may be used in

bidirectional applications.
