22      Select one of two possible clock sources for the RTC:
23        * RTC: RTC prescaler increments using RTC clock.
24        * LPO: RTC prescaler increments using 1 kHz LPO.
25      The default corresponds to the reset value of the register field,
26      and there is no additional code configuration in the driver.
