Hi, I'm trying to figure out why my basic timer interrupt on the STM32H7B3x dev board isn't working as expected. It seems to be triggering more often than I expect depending on when I clear the flag within the interrupt.

I am using the STM32H7B3LI-DK dev kit and want to use a simple timer with an interrupt. Using the most basic function, I've added a variable that simply increments within the interrupt. The timer is configured to hit the preloaded value at approx 1ms...
