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.
Register 2F ~ 5F - w: Reserved
Address [2F] - [5F] are reserved for internal use.
Register 60
-
rw: Signal Process Control A
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”.
Register 61
-
rw: Signal Process Control B
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.
