(1) Probing or otherwise stopping the crystal while the DC-DC converter is enabled may cause permanent damage to the device.
(2) The crystal startup time is low because it is kick-started by using the RCOSC_HF oscillator (temperature and aging compensated) that
is running at the same frequency.
5.12.3.2 32.768-kHz Crystal Oscillator (XOSC_LF)
Measured on the Texas Instruments CC1310EM-7XD-7793 reference design with Tc = 25°C, VDDS = 3.0 V, unless otherwise
