WebThe RTC clock source could be any of the following ones HSE clock divided by 128. LSE oscillator clock. LSI oscillator clock. Two separate reset types: The APB1 interface is reset by system reset. The RTC core is reset only by a Backup domain reset. Three dedicated maskable interrupt lines: WebThe RTC can be clocked from different sources: internal and external. It makes sense to clock it with sources that are independent of VDD: LSE or LSI. The LSI is independent from the high speed clocks and very useful for the IWDG (Independent Watchdog), but very inaccurate. So use the LSE if you need some accurate and predictable clock.
