3.1.2.3. Alignment Paired CW

Figure 10. Alignment Paired CW Format

The ALIGN CW is a paired CW with START/END or END/START CWs. You can insert the ALIGN paired CW by either asserting the tx_link_reinit signal, set the Alignment Period counter, or initiating a reset. When the ALIGN paired CW is inserted, the align field is set to 1 to initiate the receiver alignment block to check data alignment across all lanes.
