How to count the rising edge count of the waveform?

Hi

There is a square waveform and I want to count the rising edge.

Because the rising edge may caused 2000 times every second, if use irq method, the RTOS may do a lot of context switch, and I think it may waster too much.

Does the AURIX platform have any function to count the rising edge?

Can IOM be used for this case?

 

Thanks a lot.

A submodule named TIEM(TIM Input Event Mode) in TIM can count the edge.
