Chapter 6 Register Set
6.5.36 Register 34h: R_FINE
The R_FINE Register is the second adjustment for the red channel of the ADC. It is used to fine tune the
top reference used by the ADC. (See also Section 6.5.33, “Register 31h: R_COARSE”.)

These bits adjust the amount of voltage to the top reference of
the red channel of the ADC.
• 0 = Lowest-voltage value
• 255 = Highest-voltage value
6.5.37 Register 35h: G_FINE
The G_FINE Register is the second adjustment for the green channel of the ADC. It is used to fine tune the
top reference used by the ADC. (See also Section 6.5.34, “Register 32h: G_COARSE”.)

6.5.38 Register 36h: B_FINE
The B_FINE Register is the second adjustment for the blue channel of the ADC. It is used to fine tune the
top reference used by the ADC. (See also Section 6.5.35, “Register 33h: B_COARSE”.)
