Ten-bit Interface
In PCS variations with embedded PMA, the PCS function implements a TBI to an external SERDES.
On transmit, the SERDES must serialize tbi_tx_d[0], the least significant bit of the TBI output bus first
and tbi_tx_d[9], the most significant bit of the TBI output bus last to ensure the remote node receives the
data correctly, as figure below illustrates.
