XCEN
I (CMOS)
Transceiver Enable Input. Enables the bandgap reference and voltage
regulators when high. Consumes only leakage current in STANDBY
mode when low. This is a CMOS input, and the thresholds are
referenced to VCCA and VSSMX.

TXON
I (CMOS)
TX/RX Control Input. Switches the transceiver between TRANSMIT and
RECEIVE modes. Circuits are powered up and signal paths reconfigured
according to the operating mode. This is a CMOS input, and the
thresholds are referenced to VCCA and VSSMX.

RXGN
I (CMOS)
Gain Step Input Control. Switches the receiver between high gain (when
HIGH) and low gain (when LOW). This dual-gain design allows the
system designer to achieve low noise figure for low input signals while
maintaining a good IIP3 under high input signal conditions. This is a
CMOS input, and the thresholds are referenced to VCCA and VSSMX.
