will be updated by internal auto A/D BLC circuit, and write a value to this register with SCCB
has no effect. If COMG2=1, V channel offset adjustment will use the register stored value
which can be changed by SCCB. If COMF1=1, this register has no effect to A/D output data. If
output raw data, this register will adjust R/G/B data.
