In single-width mode, the PMA-PCS interface is either 8 or 10 bits wide. In 8-bit wide
PMA-PCS interface modes, the word aligner receives 8-bit wide data from the
deserializer. In 10-bit wide PMA-PCS interface modes, the word aligner receives
10-bit wide data from the deserializer. Depending on the configured functional mode,
you can configure the word aligner in manual alignment mode, automatic
synchronization state machine mode, or bit-slip mode.
The following functional modes support the 8-bit PMA-PCS interface:

In manual alignment mode, the word aligner operation is controlled by the input
signal rx_enapatternalign. The word aligner operation is edge-sensitive to the
rx_enapatternalign signal. After de-assertion of rx_digitalreset, a rising edge on
the rx_enapatternalign signal triggers the word aligner to look for the word
alignment pattern in the received data stream. In SONET/SDH OC-12 and OC-48
modes, the word aligner looks for 16'hF628 (A1A2) or 32'hF6F62828 (A1A1A2A2),
