5.3.1.3.6. 8B/10B Encoder Byte Reversal Feature

Figure 260. 8B/10B Encoder Byte Reversal Feature

The byte reversal feature is available only when the PCS-PMA interface width is 16 bits or 20 bits. Byte reversal is performed at the output of the 8B/10B Encoder and is available even when the 8B/10B Encoder is disabled. This feature swaps the LSByte with the MSByte. For example, when the PCS-PMA interface width is 16-bits, [7:0] bits (LSByte) gets swapped with [15:8] bits (MSByte).
