3.9.10 TX to RX State Machine

The TX to RX state machine initially waits for the end of an ongoing transmission by waiting for a PA output off signal coming from the flag FSCR.PAON. Then, it switches all TX DSP components off as they are deactivated by the TX DSP disable state machine. In addition, it turns the power amplifier off and enables the LNA and ADC for receive operation.

As shown in Figure 3-41, the system is now ready to run either the VCO tuning state machine or run the PLL lock state machine directly.

There are no user settings that influence the behavior of this state machine.
