I am using the KL25Z on the FRDM board. The clock is running at the default frequency of 20.97MHz. Is there is an easy way to change it to 48MHz? I see there is a function SystemCoreClockUpdate() and there are also macro definition for the MCG_MODE with MCG_MODE_FBI the one I need.
However, I cannot find (or understand) documentation on how to use these definitions.
Thanks for any help.
That would seem most likely - the clock system and its configuration is highly vendor specific, so it would be down to the vendor to provide suppoer for their particular features.
