Hi every body!!

I'm using an ST72F521R9T6 and I don't have enough place on my electronic board to put an external oscillator.

So I use the internal RC oscillator...

But how can I know the value of the internal frequency of my CPU. I've seen that this value depends on the internal components..

Is there a way to know this value?

Thanks for answering

Best regards.

Use the MCO pin. You will have to select the alternate function in MCCSR.
