Word Aligner
The word aligner in XAUI functional mode is configured in automatic
synchronization state machine mode. The Quartus II software automatically
configures the synchronization state machine to indicate synchronization when the
receiver receives four /K28.5/ comma code groups without intermediate invalid code
groups. The synchronization state machine implemented in XAUI mode is compliant
to the PCS synchronization state diagram specified in Clause 48 of the IEEE P802.3ae
specification and is shown in
