Hi, I'm a bit confused about how to USB device in the MCF52223 should be clocked.
What clock frequency should the USB device have? Is it connected to the clock tree like all the other internal devices or is it getting the clock directly from oscilator block?
 
In the MCF52223 Reference Manual Rev. 2 Figure 5-1 the USB device is not shown. Is that an error? Is the FlexCAN device replaced with USB??
 
Best Regards  Hjerrild
