why 0x40010800 + 0x0C equals 0x40010830?

I tried to access RCC_APB2ENR register as a first step to blink green led on stm32nucleo f103rb then I added 0x0C to 0x40010800(RCC base address). The expected result was 0x4001080C but the actual result was 0x40010830!!! It seems 0x0C was left…

LED Blinks "Too" Fast @ NUCLEO-H755ZI-Q

Hi! According to the STM32H755ZI's manual RM0399, §9.5.6 (pg. 377), the default clock should be 64 MHz (HSI) after reset. Since the same code worked perfectly on other devices like e.g. a NUCLEO-F303K8, I expected the (red) LED to blink with 1 Hz.…
