2. If VDD_IO ramps cannot be guaranteed, an external reset circuit is recommended, see the AX8052 Application Note: Power On Reset.

3. 20 MHz Fast RC oscillator, voltage conditioning and supervisory circuit running.

4. Power setting 14, which gives 13 dBm typical power at nominal temperature.

5. Current consumption value is given for a matching network that is optimized for maximum power (setting 14, also nominal setting).
