2× luma output enable:
0 = Output depends on bit 4, luminance bypass enabled during vertical blanking (default).
1 = Outputs 2x luma samples during the entire frame. This bit takes precedence over bit 4.
Pedestal not present:
0 = 7.5 IRE pedestal is present on the analog video input signal.
1 = Pedestal is not present on the analog video input signal (default).
Disable raw header:
0 = Insert 656 ancillary headers for raw data
1 = Disable 656 ancillary headers and instead force dummy ones (0x40) (default)
Luminance bypass enabled during vertical blanking:
0 = Disabled. If bit 7, 2× luma output enable, is 0, normal luminance processing occurs and YCbCr samples are output during
the entire frame (default).
1 = Enabled. If bit 7, 2× luma output enable, is 0, normal luminance processing occurs and YCbCr samples are output during
VACTIVE and 2× luma samples are output during VBLK. Luminance bypass occurs for the duration of the vertical blanking
as defined by registers 18h and 19h.
Luma signal delay with respect to chroma signal in pixel clock increments (range –8 to 7 pixel clocks):
1111 = –8 pixel clocks delay
1011 = –4 pixel clocks delay
1000 = –1 pixel clocks delay
0000 = 0 pixel clocks delay (default)
0011 = 3 pixel clocks delay
0111 = 7 pixel clocks delay
