Bits:

Bit 0 of register DC selects the DAC bypass mode. A value of ‘1’ outputs the incoming data directly at the
DAC[2:0] outputs.
Bits 2-1 of register DC control the DAC gain. DACG0 should be set low for NTSC and PAL-M video standards,
and high for PAL and NTSC-J video standards. DACG1 should be low when the input data format is RGB (IDF =
0-3), and high when the input data format is YCrCb (IDF = 4).
Bits 4-3 of register DC select the signal to be output from the C/H Sync pin according to
Table 9
below.

Bits 2-0 of register BCO select the signal output at the BCO pin, according to
Table 10
below:
Bit 3 of register BCO selects the polarity of the BCO output. A value of ‘1’ does not invert the signal at the output
pad.
Bit 4 of register BCO enables the BCO output. When BCOEN is high, the BCO pin will output the selected signal.
When BCOEN is low, the BCO pin will be held in tri-state mode.
