XOVEREN: Enables RSSI conversion to use the XOVER FINE (Table 02h, Register A0h –A1h) value
during MON3 conversions.
0 = Uses hysteresis for linear RSSI measurements.
1 = XOVER value is enabled for nonlinear RSSI measurements.
RESERVED
TXDM34: Enables TXD to reset alarms, warnings, and quick trips associated to MON3 and MON4
during a TXD event.
0 = TXD event has no effect on the MON3 and MON4 alarms, warnings, and quick trips.
1 = MON3 and MON4 alarms, warnings, and quick trips are reset during a TXD event.
TXDFG: See Figure 13.
0 = FETG, an internal signal, has no effect on TXDOUT.
1 = FETG is enabled and ORed with other possible signals to create TXDOUT.
TXDFLT: See Figure 13.
0 = TXF pin has no effect on TXDOUT.
1 = TXF pin is enabled and ORed with other possible signals to create TXDOUT.
TXDIO: See Figure 13.
0 = (Default) TXD input signal has no effect on TXDOUT.
1 = TXD input signal is enabled and ORed with other possible signals to create TXDOUT.
RSSI_FC and RSSI_FF: RSSI Force Coarse and RSSI Force Fine. Control bits for RSSI mode of
operation on the MON3 conversion.
00b = Normal RSSI mode of operation (default).
01b = The fine settings of scale and offset are used for MON3 conversions.
10b = The coarse settings of scale and offset are used for MON3 conversions.
11b = Normal RSSI mode of operation.
