6 AGC_LNA_PRIORITY
1
R/W Selects between two different strategies for LNA and
LNA 2 gain adjustment. When 1, the LNA gain is
decreased first. When 0, the LNA 2 gain is decreased
to minimum before decreasing LNA gain.
5:4 CARRIER_SENSE_REL_THR[1:0] 0 (00) R/W Sets the relative change threshold for asserting carrier
sense

3:0 CARRIER_SENSE_ABS_THR[3:0] 0
R/W Sets the absolute RSSI threshold for asserting carrier
(0000)
sense. The 2-complement signed threshold is
programmed in steps of 1 dB and is relative to the
MAGN_TARGET setting.
