This section provides a step-by-step procedure to run a matrix and shape-scan. The

shape-scan procedure is described first.

Shape-Scan Procedure:

1. Ensure the offset and step parameters described in Table 4-6 are set to their default

values.

2. Configure the 4-point error rate threshold by setting each of the parameters listed

in Table 4-7.

3. Configure the eye monitor to run a shape-scan by setting

CTRL_EYE_SHAPE_SCAN_B to 1.

4. Start the scan and poll the scanner status register until the scan is complete. Please

refer to the flow diagram in Figure 4-10.
