Example 4
Suppose that the start scan input channel is AI14 and the stop scan
input channel is AI3. If AI14 is D, AI0 and AI1 are S, AI2 is D, then the
scan sequence is AI14, AI0, AI1, AI2, AI14, AI0, AI1, AI2, AI14, AI0,
AI1...
Example 5
Suppose that the start scan input channel is AI11 and the stop scan
input channel is AI15. If AI11 is S, AI12 is D, AI14 is D, then the scan
sequence is AI11, AI12, AI14, AI11, AI12, AI14, AI11, AI12...
Example 6
Suppose that the start scan input channel is AI4 and the stop scan
input channel is AI7. If AI4 is S, AI5 is D, AI6 is D, then the scan
sequence is AI4, AI5, AI7, AI4, AI5, AI7, AI4, AI5...
Note
This is an error setting of channel scan sequence, user have to avoid
setting even channel as S and odd channel as D.
