Can i mesure period of High Speed External (HSE) oscillator period with help of  DWT?
I initialized DWT and can mesure number of cycles of operations.

I use stm32f207 microcontroller.
Thanks in advice.

p.s. Or maybe are there some other better methods. For example use Timers (is it possible to mesure 20 MHz signal?)
