520 | is the responsibility of the module using the tda9887 to set | |
521 | these values in case of changes in the tvnorm. | |
522 | In many cases port 2 should be made active (0) when selecting | |
523 | SECAM-L, and port 2 should remain inactive (1) for SECAM-L'. | |
524 | ||
525 | For the other standards the tda9887 application note says that | |
