5.3.2.1.6. Word Aligner RX Bit Reversal Feature

The RX bit reversal feature reverses the order of the data received from the PMA. It is performed at the output of the Word Aligner and is available even when the Word Aligner is disabled. If the data received from the PMA is a 10-bit data width, the bit reversal feature switches bit [0] with bit [9], bit [1] with bit [8], and so on. For example, if the 10-bit data is 1000010011, the bit reversal feature, when enabled, changes the data to 1100100001.
