During the duration of the vertical blanking as defined by the VBLK start and stop line registers at
subaddresses 22h through 25h (see Sections 2.11.22 and 2.11.23), the chroma samples are replaced by luma
samples. This feature can be used to support VBI processing performed by an external device during the
vertical blanking interval. In order to use this bit, the output format must be 10-bit ITU-R BT.656 mode.
Luminance signal delay [3:0]: Luminance signal delays with respect to the chroma signal in 1
