Table 21. Si472x Property Summary (Continued)
Enables interrupt sources.
Configure digital audio outputs (Si4721 only)
Configure digital audio output sample rate (Si4721 only)
Sets the limiter release time. Default is 102 (5.01 ms)
Configures measurements related to signal quality met-
rics. Default is none selected.
Configures low audio input level detection threshold.
This threshold can be used to detect silence on the
incoming audio.
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.
Si4721 Only. Configure RDS interrupt sources. Default
is none selected.
Si4721 Only. Sets transmit RDS program identifier.
Si4721 Only. Configures mix of RDS PS Group with
RDS Group Buffer.
Si4721 Only. Miscellaneous bits to transmit along with
RDS_PS Groups.
Si4721 Only. Number of times to repeat transmission of
a PS message before transmitting the next PS mes-
sage.
Si4721 Only. RDS Program Service Alternate Fre-
quency. This provides the ability to inform the receiver of
a single alternate frequency using AF Method A coding
and is transmitted along with the RDS_PS Groups.
Si4721 Only. Number of blocks reserved for the FIFO.
Note that the value written must be one larger than the
desired FIFO size.
Sets the release time for audio dynamic range control.
Default is 4 (1000 ms).
Sets the gain for audio dynamic range control.
Default is 15 dB.
