Red channel offset DAC value.
Green channel offset DAC value
Blue channel offset DAC value
A write to this register location causes the red, green and blue offset DAC
registers to be overwritten by the new value
Determines the gain of the red channel PGA according to the equation:
Red channel PGA gain = 208/(283-PGA[7:0])
Determines the gain of the green channel PGA according to the equation:
Green channel PGA gain = 208/(283-PGA[7:0])
Determines the gain of the blue channel PGA according to the equation:
Blue channel PGA gain = 208/(283-PGA[7:0])
A write to this register location causes the red, green and blue PGA gain
registers to be overwritten by the new value
