Esp32S3 : Is there any input capture function/module in the Esp32S3 please ?

[ThomasESP32]

Good morning,

I am working with an Esp32S3 in a project and I need to determine the frequency of an external clock
running normally at 32768 Hz (which can drift).

Do you think the esp32S3 has an input capture module that I can use to count the number of rising edge
of that clock per second please ?
If the answer is yes, do you think I can use the pin 18 for that clock in order to realise this function ?

Could you help me on the subject please ?
Best regards,

Also the MCPWM module may have something you can use.

Thank you, using the pulse counter module, I managed to implement the functionnality.
