Table 13. Si473x Property Summary (Continued)
Sets high threshold for SNR interrupt.
Sets low threshold for SNR interrupt.
Sets high threshold for RSSI interrupt.
Sets low threshold for RSSI interrupt.
Sets the blend threshold for blend interrupt when boundary is
crossed.
Sets the attack and decay rates when entering and leaving soft
mute.
Sets maximum attenuation during soft mute (dB). Set to 0 to dis-
able soft mute. Default is 16 dB.
Sets SNR threshold to engage soft mute. Default is 4 dB.
Sets the bottom of the FM band for seek. Default is 8750.
Sets the top of the FM band for seek. Default is 10790.
Selects frequency spacing for FM seek.
Sets the SNR threshold for a valid FM Seek/Tune. Default value
is 3 dB.
Sets the RSSI threshold for a valid FM Seek/Tune. Default
value is 20 dBuV.
Configures RDS interrupt behavior.
Sets the minimum number of RDS groups stored in the receive
RDS FIFO required before RDS RECV is set.
Configures RDS setting.
Sets deemphasis time constant. Can be set to 50 us. Deempha-
sis is disabled by default.
Selects the bandwidth of the channel filter for AM reception. The
choices are 6, 4, 3, or 2 (kHz). The default bandwidth is 2 kHz.
Configures interrupt related to Received Signal Quality metrics.
All interrupts are disabled by default.
Sets high threshold for SNR interrupt. The default is 0 dB.
Sets low threshold for SNR interrupt. The default is 0 dB.
Sets high threshold for RSSI interrupt. The default is 0 dB.
Sets low threshold for RSSI interrupt. The default is 0 dB.
Sets the rate of attack when entering or leaving soft mute. The
default is 278 dB/s.
Sets the AM soft mute slope. The bigger the number, the higher
the max attenuation level. Default value is a slope of 2.
