Set to zero for normal operation.
Sets the -3dB corner of the highpass filter used for DC offset removal at
baseband (only possible when the automatic DC-offset-cancellation bit
(CONFIG.B5) is disabled):
0 0 = 8.6kHz highpass corner
0 1 = 17.2kHz highpass corner
1 0 = 100kHz highpass corner
1 1 = 1MHz highpass corner
Zero shuts down everything except serial interface and registers, retaining
their values.

Sets LNA operating mode according to the following:
1 = high gain
0 = low gain
Sets mixer linearity in high-gain mode:
0 = medium linearity
1 = high linearity
Sets MIXER operating mode according to the following:
1 = high gain
0 = low gain
Sets output common-mode voltage for baseband I/Q outputs:
0 = 1.2V
1 = 1.42V
