// Change History:
// $Log: usbf_rf.v,v $
// Revision 1.6 2003/10/17 02:36:57 rudi
// - Disabling bit stuffing and NRZI encoding during speed negotiation
// - Now the core can send zero size packets
// - Fixed register addresses for some of the higher endpoints
// (conversion between decimal/hex was wrong)
// - The core now does properly evaluate the function address to
// determine if the packet was intended for it.
// - Various other minor bugs and typos
//
// Revision 1.5 2001/11/04 12:22:45 rudi
//
// - Fixed previous fix (brocke something else ...)
// - Majore Synthesis cleanup
//
// Revision 1.4 2001/11/03 03:26:23 rudi
//
// - Fixed several interrupt and error condition reporting bugs
//
// Revision 1.3 2001/09/24 01:15:28 rudi
//
// Changed reset to be active high async.
//
// Revision 1.2 2001/08/10 08:48:33 rudi
//
// - Changed IO names to be more clear.
// - Uniquifyed define names to be core specific.
//
// Revision 1.1 2001/08/03 05:30:09 rudi
//
//
// 1) Reorganized directory structure
//
// Revision 1.2 2001/03/31 13:00:52 rudi
//
// - Added Core configuration
// - Added handling of OUT packets less than MAX_PL_SZ in DMA mode
// - Modified WISHBONE interface and sync logic
// - Moved SSRAM outside the core (added interface)
// - Many small bug fixes ...
//
// Revision 1.0 2001/03/07 09:17:12 rudi
//
//
// Changed all revisions to revision 1.0. This is because OpenCores CVS
// interface could not handle the original '0.1' revision ....
//
// Revision 0.2 2001/03/07 09:08:13 rudi
//
// Added USB controll signaling (Line Status) block. Fixed some minor
// typos, added resume bit and signal.
//
// Revision 0.1.0.1 2001/02/28 08:11:32 rudi
// Initial Release
