Any Core Hardware Register available to user which is not used by HAL or the Processor itself which I can safely use without disturbing the rest of the MCU?I am using an STM32L431. To keep the System State in check I am using a Volatile uint32_t vari...

I checked everything today and worked as expected. Thanks.Just moved from a custom board that used STMG0 to a STM32H723. I am so ecstatic to finally be able to figure out TCM, Cache Write back, and just trying to unlock every bit of performance. Kind...
