There is a bug in F0 LL library rcc module.
RCC_GetSystemClockFreq() is incorrect if the mcu use HSI48 as system clock,
in this case it returns HSI_VALUE but not 48MHz.
This is forwarded internally to the appropriate team and will be fixed in next releases.
Thanks for bringing this to our attention and for your contribution to the enhancement of our STM32 resources.
