CM Offset: Fine bottom-level clamp common mode offset enable. The common mode offset is approximately 300 mV when enabled. Has no

effect when the coarse clamp or fine mid-level clamp is selected. See registers 10h and 2Dh.

0 = Common mode offset disabled (default)

1 = Common mode offset enabled

Note: The 300-mV common-mode offset can be enabled to improve isolation and channel crosstalk, when inputs with sync

tips larger than nominal (>300 mV) must be supported.

Reserved [6:5]:

0 = Normal operation (default)

Fine swsel: Fine clamp time constant adjustment

00 = Longest time constant (default)

11 = Shortest time constant

Reserved [2]:

1 = Normal operation (default)

Fine GB: Active high fine clamp enable for Green and Blue channel

0 = Green channel fine clamp disabled

1 = Green and Blue channel fine clamps enabled (default)

Fine R: Active high fine clamp enable for Red channel

0 = Red channel fine clamp disabled

1 = Red channel fine clamp enabled (default)

Note: Leave Fine GB and Fine R bits turned on for proper clamp operation. See register 10h for mid and bottom level clamping control.

0 = ADC green channel power-down disabled (default)

1 = ADC green channel power-down enabled

PW ADC R: Active high power-down for ADC red channel

0 = ADC red channel power-down disabled (default)

1 = ADC red channel power-down enabled
