3.9.9 RX to TX State Machine

The RX to TX state machine disables all components that would be disabled by the RX disable state machine. These are the RX DSP, the IF amplifier, the antenna damping and the ADC clock. It, additionally, turns the LNA and the ADC off completely. If configured in SSMCR.SETRPA/B, it disables the transparent outputs as well.

After the RX to TX state machine is done, the system is ready to start the TX path beginning with the PLL lock state machine or optionally with the VCO tuning state machine, as shown in Figure 3-40.
