  36  *  code sections depending on if they are defined or not.

  46  *  tokens may be defined, to allow the user code to conditionally enable or disable
  47  *  code based on the USB controller family and allowable USB modes. These tokens may
  48  *  be tested against to eliminate code relating to a USB mode which is not enabled for
