1. VDD=3.3 V, Temperature =25 °C
2. See crystal or resonator manufacturer's recommendation
3. Cx,Cy can be provided by using either the integrated capacitors or by using external components.
4. When low power mode is selected, RF is integrated and must not be attached externally.
5. The EXTAL and XTAL pins should only be connected to required oscillator components and must not be connected to any
other devices.
