Is there a way to find out the reset cause by reading register or such, on STM32F429ZI Micro?

I have found the RCC( Reset and clock control) module, I think this is the one which tells us the reset cause. please confirm!!

The CSR register of the RCC module stores flags for recent reset reasons (e.g. software, watchdog, brownout). To acquire the last reset's cause you should clear these flags after you have read them, as they are only cleared by software.
