The rx_syncstatus signal is not available in bit-slipping mode.
Channel Aligner
The channel aligner is available only in XAUI mode and aligns the signals
of all four channels within a transceiver. The channel aligner follows the
IEEE 802.3ae, clause 48 specification for channel bonding.
The channel aligner is a 16-word FIFO buffer with a state machine
controlling the channel bonding process. The state machine looks for an
/A/ (/K28.3/) in each channel, and aligns all the /A/ code groups in the
transceiver. When four columns of /A/ (denoted by //A//) are
detected, the rx_channelaligned signal goes high, signifying that all
the channels in the transceiver have been aligned. The reception of four
consecutive misaligned /A/ code groups restarts the channel alignment
sequence and sends the rx_channelaligned signal low.
