Hello again...

I did some tests and i get this results :

- receive stream : - 8 bits data signal

- 1 bit ready signal

- 1 bit valid signal

- 5 bits error signal

- 1 bit sop

- 1 bit eop

[/INDENT][/INDENT]- transmit stream : - 8 bits data signal

- 1 bit ready signal

- 1 bit valid signal

- 1 bit error signal

- 1 bit sop

- 1 bit eop

[/INDENT][/INDENT]- receive_packet_type : - 1 bit valid signal

- 5 bit data signal

[/INDENT][/INDENT]- receive_fifo_status : - 2 bits data signal

- 1 bit valid signal

[/INDENT][/INDENT]but i still don't know what's in the two last streams receive_fifo_status and receive_packet_type... and i still don't have any piece of information...

Could anyone help?

Thanks.
