data according to type, sending one kind to FIFO A and the other kind to FIFO
B. Then, at the outputs, each data type is transferred to its appropriate
destination. Additional IDT72801/72811/72821/72831/72841/72851s permt
more than two priority levels. Priority buffering is particularly useful in network
applications.
The two FIFOs contained in the IDT72801/72811/72821/72831/72841/
72851 can be used to prioritize two different types of data shared on a system
bus. When writing fromthe bus to the FIFO, control logic sorts the intermxed

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.
