Width Expansion Configuration
Word width may be increased simply by connecting the corre-
sponding input control signals of FIFOs A and B. A composite
flag should be created for each of the end-point status flags
EFA and EFB, also FFA and FFB. The partial status flags
PAEA, PAFB, PAFA, PAFB can be detected from any one de-
vice. Figure 3 demonstrates an 18-bit word width using the two
FIFOs contained in one CY7C4801/4811/4821/4831/4841
/4851. Any word width can be attained by adding additional
CY7C4801/4811/4821/4831/4841/4851s.
When the CY7C4801/4811/4821/4831/4841/4851 is in a
Width Expansion Configuration, the Read Enable 2 (RENA2
and RENB2) control unputs can be grounded (see Figure 3).
In
this
configuration,
the
(WENA2/LDA,WENB2/LDB) pins are set LOW at Reset so that
the pin operates as a control to load and read the programma-
ble flag offsets.
