The 8B/10B decoder takes a 10-bit encoded value as input and produces an 8-bit data value and 1-bit control value as output.
Figure 47. Decoding for GbEDx.y(0x8d), Dx.y(0xa4), K28.5(0xbc), and Dx.y(0x50) are received at rx_parallel_data. /K28.5/ is set as the word alignment pattern. rx_patterndetect goes high whenever it detects /K28.5
