34.4.16 Color Space Conversion Coefficient Register 2
This register contains color space conversion coefficients in two's compliment notation.
The Coeffient 2 register contains coeffients used in the color space conversion algorithm.
C2 is the coeffient that is used to multiply the chroma (Cr/V) component of the data for the
green component. C3 is the coeffient that is used to multiply the chroma (Cb/U) component
of the data for the green component. Both values should be coded as a two's compliment
fixed point number with 8 bits right of the decimal.
