| 21 | to select the correct routing: the operating mode and the selection | |
| 22 | of the Y input (external or internal). | |
| 23 | ||
| 24 | The first two operating modes expect a composite signal on the Y input, | |
| 25 | the second two operating modes use both the Y and C inputs. | |

| 28 | YCNR mode is used for S-Video inputs. | |

| 30 | The external Y-ADC is selected when the composite input comes from a | |
| 31 | upd64031a ghost reduction device. If this device is not present, or | |
| 32 | the input is a S-Video signal, then the internal Y-ADC input should | |
