MPCER can count a number of different things. What specifically are you counting?


Yes, Sorry, I meant I set MPCER to 0x01 to count CPU cycles and then measure the cycles using MPCCR register. I also set MPCER to 0x02 to measure the number of instructions.

Here's the part of the code I use ...

I am doing a project using the ESP32-C3 development board.

I wanted to measure the clock cycles it takes while a function is called the first time and when it is called again (basically measuring the miss and hit cycles for instruction load from the flash). I wrote a basic function in assembly ...
