pointers for obtaining the 6X register data for passing to the appropriate 4X XMIT parameterization
registers. Figure 37 illustrates the logic to accomplish this task.
Figure 37. Segment 3 Network 8 – Cyclic Poll Cessation Logic
Segment 3 Network 9:
As illustrated, this is essentially a copy of Segment 3 Network 3 logic. It is copied here in order to keep
the same philosophy for instruction parameter loading whether it is from a cyclic poll request or a FIFO
task interruption. The logic is shown in Figure 38.
Figure 38. Segment 3 Network 9 – XMIT Pointer Computation Logic
Segment 3 Network10:
This network determines that the FIFO is empty and cyclic polling using the logic in Segment 3 Network 2
resumes. The Logic is illustrated in Figure 39.
