0 = Interlaced operation.
1 = Noninterlaced operation.
0 = CCIR601 operation.
1 = Square pixel operation.
0 = The I2C read-back information contains the version number.
1 = The I2C read-back information contains closed-captioning status and field number.
0 = Normal operation.
1 = Enable RGB outputs.
The RGBOUT pin is logically ORed with the RGBO register bit.
0 = Normal operation.
1 = Blank chroma.
0 = Normal operation.
1 = Enable color bars.
0 = Normal operation. The subcarrier phase is reset to zero at the beginning of each color field
1 = Disable subcarrier reset event at beginning of field sequence.
0 = Video is blanked during the vertical blanking interval.
1 = Enable active video during vertical blanking interval. Setup is added during VBI, if SETUPDIS = 0,
0 = Black burst (only if ECBAR = 0).
1 = Enable normal video.
0 = Normal operation.
1 = Enable clipping; DAC values less than 63 are made 63. This limit corresponds to roughly one-fourth
