Reserved. Set to 0 for normal operation.
Works with RCP_TURBO2 (in the configuration register) to set the turbo
charge-pump mode (see Table 7).

Reserved. Set to 01 for normal operation.
Reserved. Set to 00 for normal operation.
3-bit gain balancing control. Increases IF gain by approximately 2dB per
LSB. Provides a means for adjusting balance between RF and IF gain for
optimized linearity.
Reserved. Set to 0 for normal operation.
LO buffer enable.
0 = LO buffer off.
1 = LO buffer on.
Selects type of modulation.
0 = Selects direct VCO modulation (IF VCO is directly modulated and the
I/Q modulator is bypassed).
1 = Selects quadrature modulation.
Standby control.
0 = Shuts down everything except the registers and serial interface.
1 = Normal operation.
Transmitter standby control.
0 = Shuts down the modulator and upconverter leaving PLLs locked and
registers active. This bit’s functionality is equivalent to that of the
TX_GATE pin.
1 = Normal operation.
Shutdown control.
0 = Shuts down everything except the serial interface.
1 = Normal operation.
