DC_Offset[3:0]
Bit 1
Bit 0
Bits 3–0: Determines the video reference level at the RGB video outputs on pins 57, 58 and 59. A setting of 0xF gives a DC
Offset of about 0.5V and 0x0 gives a DC Offset of about 1.4V.

C auto increment function is active. When set to a 1, the I
2
C auto increment function is disabled. In
the auto increment mode, a given register can be updated continuously using an ADDR - DATA - DATA - ... - DATA
transmission sequence.
Bit 5: When set to 0, the outputs of DACs 1–3 are full scale (0V–4.2V). When this bit is a 1, the output DC range is halved
