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 LH540202 devices in par-
allel, but in opposite directions. The Data In inputs of each
LH540202 are tied to the corresponding Data Out outputs
of another LH540202, 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.
