Altera transceiver bits swapped

Thanks a lot dwesterg,

So for a "raw" transmission i need to implement myself a synch word and a FSM to realign the received data, right?

But if i use a protocol (eg basic x4) i see in the signaltap anlyzer that the bits keep swapping.

let's say the synch word is "0101111100", is it sent automatically or do i need to inject it periodically in the data?

Thanks again!

Marco

(EDIT)

the answer was yes, i need to inject the synch word and use an optional port to tell the transceiver when to realign.

tnx
