    change clock source in operation


      Is this possible? We are hoping to change between PLL1 which is ECO trimmed to Direct_Sel or something else that can be sourced from IMO and USB trimmed. The reason why is that when power is disconnected from the host Laptop, the communication timing appears to change a little bit, and when the clock is trimmed by the host it seems to handle it better. I am hoping to change the clock source whenever VBus is detected but return to normal when it is disconnected to keep good timing on a CAN bus also connected to the micro.
