http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif Hello, everyone 

I tried to layout a nios board myself, and I followed with the Demo board.  But I found I couldn&#39;t know how does the Lan91c1111 work, synch or asynch?  I read the Lan91c1111 datasheet, and I found the demo board connected both the synch and asynch control signals.   The question is how the SOPC&#39;s Lan91c1111 works , and then I could choose the real one, to reduce my FPGA&#39;s pins.    Thank you in advance!!
