BIT 7
XOVEREN: Enables RSSI conversion to use the XOVER (A2h Table 02h, Register 90h–91h) value
during RSSI conversions.
0 = Uses hysteresis for linear RSSI measurements.
1 = XOVER value is enabled for nonlinear RSSI measurements.
BIT 6
RESERVED
BIT 5
TXDM3: Enables TXD to reset alarms and warnings associated to RSSI during a TXD event.
0 = TXD event has no affect on the RSSI alarms and warnings.
1 = RSSI alarms and warnings are reset during a TXD event.
BIT 4
RESERVED
BIT 3
TXDFLT: See Figure 10.
0 = TXF pin has no affect on TXDOUT.
1 = TXF pin is enabled and ORed with other possible signals to create TXDOUT.
BIT 2
TXDIO: See Figure 10.
0 = TXD input signal is enabled and ORed with other possible signals to create TXDOUT.
1 = (Default) TXD input signal has no affect on TXDOUT.
BITS 1:0
RSSI_FC and RSSI_FF: RSSI force coarse and RSSI force fine. Control bits for RSSI mode of
operation on the RSSI conversion.
00b = (Default) Normal RSSI mode of operation.
01b = The fine settings of scale and offset are used for RSSI conversions.
10b = The coarse settings of scale and offset are used for RSSI conversions.
11b = Normal RSSI mode of operation.
