Table 12. Si473x Command Summary
Table 13. Si473x Property Summary
Power up device and mode selection. Modes include AM or FM receive and
reference clock or crystal support.
Returns revision information on the device.
Power down device.
Sets the value of a property.
Retrieves a property’s value.
Read interrupt status bits.
Reserved command used for firmware file downloads.
Reserved command used for firmware file downloads.
Selects the FM tuning frequency.
Begins searching for a valid frequency
Queries the status of previous FM_TUNE_FREQ or FM_SEEK_START
command.
Queries the status of the Received Signal Quality (RSQ) of the current
channel.
Returns RDS information for current channel and reads an entry from the
RDS FIFO (Si4731 only).
Tunes to a given AM frequency.
Begins searching for a valid frequency.
Queries the status of the already issued AM_TUNE_FREQ or
AM_SEEK_START command.
Queries the status of the Received Signal Quality (RSQ) for the current
channel.
Sets the prescaler value for RCLK input.
Enables interrupt sources.
Sets frequency of reference clock in Hz. The range is 31130 to
34406 Hz, or 0 to disable the AFC. Default is 32768 Hz.
Sets deemphasis time constant. Default is 75 us.
Sets RSSI threshold for stereo blend (Full stereo above thresh-
old, blend below threshold). To force stereo set this to 0. To
force mono set this to 127. Default value is 49 dBuV.
Sets RSSI threshold for mono blend (Full mono below thresh-
old, blend above threshold). To force stereo set this to 0. To
force mono set this to 127. Default value is 30 dBuV.
Sets the maximum freq error allowed before setting the AFC rail
(AFCRL) indicator. Default value is 30 kHz.
Configures interrupt related to Received Signal Quality metrics. 0x0000
