0012    to select the correct routing: the operating mode and the selection
0013    of the Y input (external or internal).
0014
0015    The first two operating modes expect a composite signal on the Y input,
0016    the second two operating modes use both the Y and C inputs.
0017
0018    Normally YCS_MODE is used for tuner and composite inputs, and the
0019    YCNR mode is used for S-Video inputs.
0020
0021    The external Y-ADC is selected when the composite input comes from a
0022    upd64031a ghost reduction device. If this device is not present, or
0023    the input is a S-Video signal, then the internal Y-ADC input should
0024    be used. */
