TX_ASQ_DURATION_LOW
TX_ASQ_LEVEL_HIGH
TX_ASQ_DURATION_HIGH
TX_RDS_INTERRUPT_SOURCE
Configures the duration which the input audio level must
be below the low threshold in order to detect a low audio
condition.
Configures high audio input level detection threshold.
This threshold can be used to detect activity on the
incoming audio.
Configures the duration which the input audio level must
be above the high threshold in order to detect a high
audio condition.
