(1) Probing or otherwise stopping the XTAL while the DC-DC converter is enabled may cause permanent damage to the device.
(2) Includes initial tolerance of the crystal, drift over temperature, ageing and frequency pulling due to incorrect load capacitance. As per
Bluetooth and IEEE 802.15.4 specification.
(3) Kick-started based on a temperature and aging compensated RCOSC_HF using precharge injection.
