4, 5: C levels
This data specifies the white detection region.
Of all 8 bits of this data, the data that can be changed consists of 7 bits (128/256 = 1/2), and the white
detection region can be changed over up to 1/2 of the full data range.
The C level data correspondences are as follows:
C level 1 + → The down direction of the (Mg-G) signal.
C level 1 – → The down direction of the (R-B) signal.
C level 2 + → The up direction of the (Mg-G) signal.
C level 2 – → The up direction of the (R-B) signal.
