I'm analyzing some code downloaded from a STM32F401 and have come across references to reserved memory addresses 0x42470000 and 0x42470E80, so my question is what do these addresses belong to please?
These are bit-banded aliases into RCC, in particular 0x42470000=0x4002'3800 bit 0 i.e. RCC_CR.HSION, and 0x42470E80 = 0x4002'3874 bit 0 i.e. RCC_CSR.LSION.
