NOTES:
1. FIFO is initially full.
2. SO pulse is applied.
3. SI is held HIGH.
4. As soon as IR becomes HIGH the Input Data is loaded into the FIFO.
5. The write pointer is incremented. SI should not go LOW until (t
OUTPUT DATA
NOTES:
1. This data is loaded consecutively A, B, C.
2. Data is shifted out when SO makes a HIGH to LOW transition.
OUTPUT DATA
NOTES:
1. OR HIGH indicates that data is available and a SO pulse may be applied.
2. SO goes HIGH causing the next step.
3. OR goes LOW.
4. The read pointer is incremented.
5. OR goes HIGH indicating that new data (B) is now available at the FIFO outputs.
6. If the FIFO has only one word loaded (A DATA) then OR stays LOW and the A DATA remains unchanged at the outputs.
7. SO pulses applied when OR is LOW will be ignored.
