8.4.4 RTC prescaler divider register (RTC_DIVH / RTC_DIVL)
During each period of TR_CLK, the counter inside the RTC prescaler is reloaded with the
value stored in the RTC_PRL register. To get an accurate time measurement it is possible to
read the current value of the prescaler counter, stored in the RTC_DIV register, without
stopping it. This register is read-only and it is reloaded by hardware after any change in the
RTC_PRL or RTC_CNT registers.
