CONTROLS:
SHIFT IN (SI)
can be written to the FIFO via the D0-4 lines. The data has to meet set-up and
hold time requirements with respect to the rising edge of SI.
SHIFT OUT (SO)
MASTER RESET (MR)
FIFO should be cleared with a Master Reset. Master Reset is active LOW.
HALF-FULL FLAG (HF)
INPUT READY (IR)
to it. When IR is LOW, the FIFO is unavailable for new input data, IR is also
used to cascade many FIFOs together, as shown in Figure 13.
NOTES:
1. IR HIGH indicates space is available and a SI pulse may be applied.
2. Input Data is loaded into the FIFO.
3. IR goes LOW indicating the FIFO is unavailable for new data.
4. The write pointer is incremented.
5. The FIFO is ready for the next word.
6. If the FIFO is full, then IR remains LOW.
7. SI pulses applied while IR is LOW will be ignored (see Figure 4).

INPUT DATA
Shift In controls the input of the data into the FIFO. When SI is HIGH, data
Shift Out controls the outputs data from the FIFO.
Master Reset clears the FIFO of any data stored within. Upon power up, the
Half-Full Flag signals when the FIFO has 32 or more words in it.
