Table 12. Si4707 Property Summary
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 the output volume.
Mutes the audio output. L and R audio outputs may be muted
independently in FM mode.
Maximum change in frequencies from the WB_TUNE_FREQ to
which the AFC will lock.
Configures interrupts related to RSQ 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.
Configures 1050 Hz alert tone interrupts. All interrupts are
disabled by default.
Configures SAME interrupt sources. All interrupts are disabled
by default.
