Hsync polarity
Hsync is active LOW, line starts at rising edge of pin VHS
Hsync is active HIGH, line starts at falling edge of pin VHS
Vsync polarity
Vsync is active LOW, line starts at rising edge of pin VVS
Vsync is active HIGH, line starts at falling edge of pin VVS
Clamp pulse polarity
Pulse is active LOW
Pulse is active HIGH
Gain correction pulse polarity
Pulse is active LOW
Pulse is active HIGH
ADC sample sequence
ADC 0 is sampled first after Hsync (video input port A, B, C)
ADC 1 is sampled first after Hsync (video input port D, E, F)
Input interface activation
