Hi all,

I'm working with stm32f103zhc6 mcu and the issue is that I cant write AFIO_MAPR2 register. Is the issue because the register exists in XL-density devices only or some special action should be applied to get an access to this register?

Can you modify any of the AFIO registers? Is the AFIO clock enabled?

AFIO clock enabled and I can successfully write to MAPR (but not to MAPR2)

I, and apparently Google, are not familiar with your STM32F103ZH part, care to cite a data sheet for it?

Since a lot of the values appear to relate to peripherals only in the XL series parts, yes I'd assume it's related to that.
