Holdoff angle: The angle until
the scanning starts to detect the
next minimum width.
Algorithm: The algorithm
used to compute the minimum
width from the result of scanning.

Angle Limit: The angle within which if the minimum width is not detected,
an error is returned as the status of the result.
Parameters are set using LOAD_CMD (40).
