I’m facing an issue with the update event triggering in STM32 TIM1. I’ve configured TIM1 to generate PWM signals and set the update event to Center-Aligned Mode 3. However, I’ve noticed that the update event is occurring both when the timer’s counter reaches the auto-reload value (ARR) and when it reaches zero. This is causing a problem because I specifically need the update event to occur only at ARR to trigger the ADC for sampling.
