To optimize the output power spectral density (PSD), the PA buffer and PA are enabled
sequentially, see in
rising edge of pin 11 (SLP_TR). The radio transceiver state changes from PLL_ON to
BUSY_TX. The modulation of the frame starts 16µs after SLP_TR rising edge.
Register 0x05 (PHY_TX_PWR):
The PHY_TX_PWR register controls the output power of the transmitter.
Figure 9-5. Register PHY_TX_PWR.
 Bit 3:0 – TX_PWR
The register bits TX_PWR determine the TX output power of the radio transceiver.
