Description
Default
Sets the top of the AM band for seek.
0x06AE
Selects frequency spacing for AM seek. Default is 10 kHz
spacing.
0x000A
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.
0x0005
0x0019
Sets the output volume.
0x003F
Mutes the audio output. L and R audio outputs may be muted
independently in FM mode.
0x0000
Maximum change in frequencies from the WB_TUNE_FREQ to
which the AFC will lock.
0x000F
Configures interrupts related to RSQ metrics. All interrupts are
disabled by default.
0x0000
Configures 1050 Hz alert tone interrupts. All interrupts are dis-
abled by default.
