(8) Output update time unit and point-to-point interpolation method (number of data items: 1)
Set the unit of the output update time and the point-to-point interpolation method for each point.
The output update time unit and the point-to-point interpolation method for the n-th point are applied
between the n-th point and the (n+1)-th point.
When the pattern is repeated, the output update time unit and the point-to-point interpolation method are
applied between the final point and the first point.
When the pattern is not repeated, the output update time unit and the point-to-point interpolation method
for the final point are ignored.
A 4-digit hexadecimal number, H, is allocated as shown below.
