4. Setting example of the conversion table for scaling
A setting example for the 16-bit operation is shown below.
For the 32-bit operation, set each item using a 32-bit binary value.
In the case of the conversion characteristics for scaling shown in the figure below, set the following data table.

When coordinates are specified using three points in this
way, the output value can be set to an intermediate value.
In this example, the output value (intermediate value) is
specified by the Y coordinate of the point 5.
If the x coordinate is the same at three points or more, the
value at the second point is also output.

When coordinates are specified using two points in this
way, the output value is the Y coordinate at the next point.
In this example, the output value is specified by the Y
coordinate of the point 9.
