1. Use INSEL[3:0] to configure the routing and format decoding
(CVBS, Y/C, or YPrPb). For the 64-lead and 48-lead L QF P,
see Table 13. For the 40-lead and 32-lead LFCSP, see Table 14.
2. If the input requirements are not met using the INSEL[3:0]
options, the analog input muxing section must be configured
manually to correctly route the video from the analog
input pins to the ADC. The standard definition processor
block, which decodes the digital data, should be configured
to process the CVBS, Y/C, or YPrPb format. This is performed
by INSEL[3:0] selection.

INSEL[3:0] has predefined analog input routing schemes that
do not require manual mux programming (see Table 13 and
Table 14). This allows the user to route the various video signal
types to the decoder and select them using INSEL[3:0] only.
The added benefit is that if, for example, the CVBS input is
selected, the remaining channels are powered down.
