XOVEREN2: Enables RSSI conversion to use the XOVER2 value during RSSI2 conversions.
0 = Uses hysteresis for linear RSSI measurements.
1 = XOVER2 value is enabled for nonlinear RSSI measurements.
BITS 5:4
RSSI2_FC and RSSI2_FF: RSSI2 force coarse and RSSI2 force fine. Control bits for RSSI mode of
operation on the RSSI2 conversion.
00b = (default) Normal RSSI mode of operation.
01b = The fine settings of scale and offset are used for RSSI2 conversions.
10b = The coarse settings of scale and offset are used for RSSI2 conversions.
11b = Normal RSSI mode of operation.
BIT 2
XOVEREN1: Enables RSSI conversion to use the XOVER1 value during RSSI1 conversions.
0 = Uses hysteresis for linear RSSI measurements.
1 = XOVER1 value is enabled for nonlinear RSSI measurements.
BITS 1:0
RSSI1_FC and RSSI1_FF: RSSI1 force coarse and RSSI1 force fine. Control bits for RSSI mode of
operation on the RSSI1 conversion.
00b = (default) Normal RSSI mode of operation.
01b = The fine settings of scale and offset are used for RSSI1 conversions.
10b = The coarse settings of scale and offset are used for RSSI1 conversions.
11b = Normal RSSI mode of operation.
