* '''RTC Hardware clock''': hardware clock is controlled by PMIC IC using its internal RTC peripheral. RTC PMIC can afford two behaviours:
** RTC battery is not used: PMIC RTC peripheral keeps hardware clock alive when OS isn't running and power source is active. If the power source fails, the RTC Hardware clock will lose its clock.
** RTC battery is used: PMIC RTC peripheral keeps hardware clock alive when OS isn't running and backup battery powers the backup state as far as the input voltage is high enough.
