V7-V0: V channel digital output offset adjustment. Range: +128mV ~ -128mV. If COMG2=0, this register

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.

V7: Offset adjustment direction: o - Add V[6:0]; 0-Substrate V[6:0].

If COMJ0 = 0, this register value is common to U and V channel.

Address [2F] - [5F] are reserved for internal use.

SPCA7: 1.5x gain boost.

SPCA6: Reserved.

SPCA5: “1” disables green averaging for UV channel.

SPCA4: “1” disables green averaging for lumninance channel.

SPCA<3:2> Reserved.

SPCA<1:0>: Reserved. Color set to “0111”; B&W set to “0000”.

SPCB7: “1” YUV mode; “0” raw data mode.

SPCB6: Reserved. Always set to “0”.

SPCB5: Reserved. Always set to “0”.

SPCB4: Reserved. Always set to “0”.

SPCB3: Reserved. Always set to “0”.

SPCB2: Limits range of register [6] to half value.

SPCB<1:0>: Auto Brightness target reference level: (00) -- 0 IRE; (01) -- 6 IRE; (10) -- 10 IRE;

(11) -- 20 IRE.
