Version history

2010-09-12
 
 * Fixed issue with automatic discarding of TX data after link error.
 
 * After link error, spwstream will terminate current packet with EEP even
 
   if the linkdisable signal is active.
 
 * Added code comment to clarify a dependency between spwrecv and spwlink.
 
   (Thanks to Rafael Corsi Ferrao for reporting this obscurity.)
 
 
 
2010-07-12
 
 * Added manual.
 
 * Fix incorrect bitrate during link handshake. The system clock frequency
 
   was used to compute the initial tx clock divider, even when the clock
 
   divider would act on the txclk instead of the system clock.
 
 * Improve fast transmitter. Sending FCT tokens at high bit rate no longer
 
   causes insertion of a NULL token.
 
 
 
2010-06-08
 
 * Initial release.
