There was a problem hiding this comment.
so this would require the hals have these two functions. Probably not a terrible requirement for cortex chips, but at the moment they don't. We could start a discussion (on discord, but also file an issue). This PR could maybe have this part live in the stm32 hal until we get buy-in for the other HALs.
