TWO PRIORITY DATA BUFFER
CONFIGURATION
The two FIFOs contained in the IDT72801/72811/72821/72831/72841/
72851canbeusedtoprioritizetwodifferenttypesofdatasharedonasystembus.
When writing from the bus to the FIFO, control logic sorts the intermixed data

BIDIRECTIONAL CONFIGURATION
The two FIFOs of the IDT72801/72811/72821/72831/72841/72851 can
be used to buffer data flow in two directions. In the example that follows, a
processor can write data to a peripheral controller via FIFO A, and, in turn,
the peripheral controller can write the processor via FIFO B.
