To enable the 8B/10B decoder, RX_8B10B_EN must be driven High. RX_DATA_WIDTH must be set to a multiple of 10 (20 or 40) with the 8B/10B decoder enabled.

To disable the 8B/10B decoder on the GTY and GTYP receiver path, RX_8B10B_EN must be driven Low. When the decoder is disabled, RX_DATA_WIDTH can be set to a multiple of 8 or 10 (16, 20, 32, 40, 64, 80, 128, or 160). The operation of the CH*_RXDATA port with 8B/10B decoding bypassed is described in RX Interface.
