* This section describes compile tokens which affect USB driver stack as a whole in the LUFA library.

- * <b>ORDERED_EP_CONFIG</b> - (\ref Group_EndpointManagement , \ref Group_PipeManagement) - <i>AVR8 Only</i> \n
+ * <b>ORDERED_EP_CONFIG</b> - (\ref Group_EndpointManagement , \ref Group_PipeManagement) - <i>AVR8, UC3</i> \n
* The USB AVRs do not allow for Endpoints and Pipes to be configured out of order; they <i>must</i> be configured in an ascending order to
* prevent data corruption issues. However, by default LUFA employs a workaround to allow for unordered Endpoint/Pipe initialization. This compile
* time token may be used to restrict the initialization order to ascending indexes only in exchange for a smaller compiled binary size. Use
* can be accurately set and the \ref EVENT_USB_Device_Connect() and \ref EVENT_USB_Device_Disconnect() events manually raised by the RAISE_EVENT macro.
* When defined, this token disables the library's auto-detection of the connection state by the aforementioned suspension and wake up events.
*
- * <b>NO_SOF_EVENTS</b> - (\ref Group_Events) - <i>All Architectures</i> \n
+ * <b>NO_SOF_EVENTS</b> - (\ref Group_Events) - <i>AVR8, UC3</i> \n
* By default, there exists a LUFA application event for the start of each USB frame while the USB bus is not suspended in either host or device mode.
* This event can be selectively enabled or disabled by calling the appropriate device or host mode function. When this compile time token is defined,
* the ability to receive USB Start of Frame events via the \ref EVENT_USB_Device_StartOfFrame() or \ref EVENT_USB_Host_StartOfFrame() events is removed,
