KW2x - Clock at power-up

Regarding the KW21x256 Development board...

 

I'd like to learn more about the state of the clock at power-up since it does something that is a little different than what I'm used to.

My understanding is that the MCR20A transceiver has it's own crystal and that clock is initialized and shared with the MCU. Can anyone give more detail on this? What's the clock speed seen by the MCU at power-up?
