  23. to select the correct routing: the operating mode and the selection
  24. of the Y input (external or internal).
  25. The first two operating modes expect a composite signal on the Y input,
  26. the second two operating modes use both the Y and C inputs.
  27. Normally YCS_MODE is used for tuner and composite inputs, and the
  28. YCNR mode is used for S-Video inputs.
  29. The external Y-ADC is selected when the composite input comes from a
  30. upd64031a ghost reduction device. If this device is not present, or
  31. the input is a S-Video signal, then the internal Y-ADC input should
  32. be used. */
