Please go over the documentation for clock management. HFXO is only turned on upon request and is switched off automatically after the requester releases it.

what is the difference from standart clock operation?

If you want to observe the oscillations of HFXO, then you should try to request HFXO in your application like I mentioned before.

my main goal was to observe the oscillations of hfxo. however, according to my observations, there is an oscillation at 450 ms and the rest of the time it goes into low mode and is not triggered.

Hi Oguzhann,

Are you trying to see the crystal oscillations on the scope? And are you trying to do so by looking into the short time that the radio is active?

If yourmain goal is to see the crystal oscillations, I think you are better off setting up an application that request the external crystal and high frequency clock, rather than trying to catch the short radio activity interval.
