Pedestal not present:
0 = 7.5 IRE pedestal is present on the analog video input signal (default)
1 = Pedestal is not present on the analog video input signal
Luminance bypass mode during vertical blanking:
0 = No (default)
1 = Yes
When the luminance bypass is enabled, the luminance comb and notch filters are turned off and the chrominance
components of the output video are sent to a zero color state. Luminance bypass occurs for the duration of the vertical
blanking as defined by register 18 and 19. This feature may be used to prevent distortion of test and data signals
present during the vertical blanking interval.
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
