Hi guys!

I have a problem with stm32f103, I want to check MCU Reset cause, I use RCC_GetFlagStatus is ok, after that i'll clear rcc flag but It's not working & MCU not working when user RCC_ClearFlag. If i remove RCC_ClearFlag function then MCU work normal but RCC Register Reset don't clear so i don't know cause MCU reset.

I try RCC -> CSR |=0x01000000 set RMVF to clear flag but it also not working

Can you help me, thank a lot!
