STM32 TIMER synchronize with interrupt every rising edge?

[parth kothiya]

i want to control AC voltage using timer PWM mode ..

reference zero crossing signal interrupt every rising edge of zero crossing

frequency of pwm signal (100Hz) some time frequency of AC mains very between 99-100Hz so i need to synchronize my timer with every rising edge of zero crossing how can i synchronize TIMER?

You can reset or change the phase by writing into the TIMx->CNT register.​
