change HFXO from HFINT

[sfujimoto]

hello, I want to use HFXO with high accuracy. How can I switch between HFINT and HFXO?

than you,

[Wojtek]

According to documentation

The HFINT will be used when HFCLK is requested and HFXO has not been started. The HFXO is started by triggering the HFCLKSTART task and stopped using the HFCLKSTOP task. A HFCLKSTARTED event will be generated when the HFXO has started and its frequency is stable.

thank you, How can HFXO trigger the HFCLKSTART task?
