Need more understanding about the Timer enabling fn I am changing CNT register of the Timer in order to get a changed time period on the go (for down counting mode), but doing so correctly is getting delayed by one period.

So I am using STM32H725 on which I have Timer 2 (general purpose timer) which is in down counting, one pulse mode with an interrupt which is triggered at underflow. Once the interrupt is fired, the TIMx_CNT register value is changed and then __HAL_TI...
