This bit is only effective when OUT_MODE[1:0] = 11, HDTV_EN = 1, and RASTER_SEL is
nonzero.
0 = Standard color space conversion for RGB to Y (R-Y) (B-Y) based on
Y =0 .299R +0 .587G +0 .114 B (DEFAULT)
1 = HDTV color space conversion for RGB to Y (R-Y) (B-Y) based on
Y = 0.2126R + 0.7152G + 0.0722B
0 = Normal operation. (DEFAULT)
1 = Invert CVBS_DLY output.
No more than 1 DAC should be disabled at any time.
0 = Normal operation. (DEFAULT)
1 = Disables DACA output. Current is set to 0 mA; output will go to 0 V.
No more than 1 DAC should be disabled at any time.
0 = Normal operation. (DEFAULT)
1 = Disables DACB output. Current is set to 0 mA; output will go to 0 V.
