Before completing the deskew process the display on the oscilloscope screen should appear as below. F2
has been saved to M2 and has been saved to M3. The skew between M2 and M3 is calculated in P1.
This is the skew value which will be used during the testing. This value is stored in QPHY-SAS3 and it is
not necessary to re-run this process every time you run QPHY-SAS3.
