Chapter 6 Register Set

6.5.33 Register 31h: R_COARSE

The R_COARSE Register is the first adjustment for the red channel of the ADC. It is used to coarsely

adjust the analog signal used by the ADC. (See also Section 6.5.36, “Register 34h: R_FINE”.)

6.5.34 Register 32h: G_COARSE

The G_COARSE Register is the first adjustment for the green channel of the ADC. It is used to coarsely

adjust the analog signal used by the ADC. (See also Section 6.5.37, “Register 35h: G_FINE”.)
