Controls the gain common to the R, G and B channels. Since control is
performed by multiplying with R/G/B DRIVE, the white balance can be
adjusted by R/G/B DRIVE and the luminance can be adjusted by
CONTRAST.
Controls Pin 21 (R BACKGROUND) output voltage.
Controls Pin 20 (G BACKGROUND) output voltage.
Controls Pin 19 (B BACKGROUND) output voltage.
