What is the name of the ADC operation mode with peak interrupts in stm32?

Question

Microcontrollers

there is a signal that periodically crosses the threshold "zero", it is necessary that an interrupt is triggered by the maximum value of the signal, or that the interrupt is triggered when the signal reaches the threshold zero. the goal is to get an extremum on the interval between two "threshold zeros"

Answer 1

I don’t know what it is called specifically in STM32, but in general it is called Comparator
