Quad Input RGB VIC

The Quad Input RGB VIC consists of four sets of RGBHV inputs
and operates in a manner similar to a switcher. The four inputs are
multiplexed so that only one is enabled at a specific time.
Software selects the desired input channel through the IIC bus
and ensures that only one RGB VIC is enabled. When one of the
channels assigned to the Quad RGB VIC is selected, the
/SEL_VIC line to the Video Processor is enabled.
