I would like to use the KL25 Freedom board and running the RTC.
But the clock sources for the RTC are RTC_CLKIN, or 32KHz crystal which need external component, or the LPO 1KHz signal.
Is there a way to get 1 second time base with the LPO? I don't know how to configure the RTC to manage this not 32KHz frequency.
Thank you for your help.
