External 32kHz crystal has a nominal frequency of 32.768kHz and provides good frequency
stability. If used as Bluetooth low power clock, External 32kHz can support Bluetooth

Internal 150kHz RC oscillator. The accuracy of this clock is a lot larger than 500ppm which is required
in Bluetooth communication, so don't select this option in scenarios such as BLE connection state.
