With FIFO empty; SO is held HIGH in anticipation
Notes to Fig.10
1. FIFO is initially empty, SO is held HIGH
2. SI pulse; loads data into FIFO and initiates ripple through process
3. DOR flag signals the arrival of valid data at the output stage
4. Output transition; data arrives at output stage after the specified propagation delay between the rising edge of the
5. DOR goes LOW; data shift-out is complete, FIFO is empty again
6. SO set LOW; necessary to complete shift-out process. DOR remains LOW, because FIFO is empty.
