0: AC coupled (positive input connected to clamp DAC
during clamp time, negative input disconnected from
outside pad and always internally tied to appropriate
clamp DAC).
1: DC coupled (+ and - inputs are brought to pads and
never connected to clamp DACs). Analog clamp
signal is turned off in this mode.

0: DC restore clamping and ABLC™ suspended
during COAST.
1: DC restore clamping and ABLC™ continue during

0: Interval between HSYNC pulses masked
(preventing PLL from seeing Macrovision and any
spurious glitches).
1: Interval between HSYNC pulses not masked
(Macrovision will cause PLL to lose lock).
