Sets the top of the AM band for seek.
Selects frequency spacing for AM seek. Default is 10 kHz
spacing.
Sets the SNR threshold for a valid AM Seek/Tune. If the value is
zero, then SNR threshold is not considered when doing a seek.
Default value is 5 dB.
Sets the RSSI threshold for a valid AM Seek/Tune. If the value
is zero, then RSSI threshold is not considered when doing a
seek. Default value is 25 dBuV.
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.
Configures 1050 Hz alert tone interrupts. All interrupts are dis-
abled by default.
