How to use the HFXO in nRF Connect SDK

[Alex Guo]

Hi,

I want to use the 64MHz crystal oscillator (HFXO) as the source for HFCLK clock controller. How can I need to enable or disable the item in KConfig on nRF Connect SDK?

Hope your reply, many thanks.

Hi Alex, 

Could you let me know what you want to achieve ?
Note that by default if you use the radio, the SoC in the ramp-up period will automatically start the crystal and use it as the HFCLK source before transmitting/receiving. You don't have to do any extra configuration.
