NOTE
The internal 32.768-kHz crystal oscillator is kept enabled by default when the chip goes to
hibernate in response to nHIB being pulled low.

(1) Ensure that the nHIB low duration is not less than the specified width under all conditions, including power-ON, MCU hibernation, and so
forth.
(2) If temperature changes by more than 20°C, initialization time from HIB can increase by 200 ms due to radio calibration.
