R/W Selects between two different strategies for LNA and LNA2
gain adjustment. When 1, the LNA gain is decreased first.
When 0, the LNA2 gain is decreased to minimum before
decreasing LNA gain.
R/W Sets the relative change threshold for asserting carrier sense

R/W Sets the absolute RSSI threshold for asserting carrier sense
(Equal to channel filter amplitude when AGC has not
decreased gain). The 2-complement signed threshold is
programmed in steps of 1 dB and is relative to the
MAGN_TARGET setting.
