How can I set the timer to trigger ADC on counter overflow?

Hi,

I have set the timer4 in center alligned mode 3 and I want to trigger ADC on counter overflow. If I understand correctly the ADC trigger input TIM4_TRGO can be set in timer configuration as update event output but that means also in underflow will send the timer a trigger for conversion.

Do you know any solution?
