5.3.2.4.1. 8B/10B Decoder Control Code Encoding

Figure 203. 8B/10B Decoder in Control Code Group Detection

The 8B/10B decoder indicates whether the decoded 8-bit code group is a data or control code group on rx_datak . If the received 10-bit code group is one of the 12 control code groups (/Kx.y/) specified in the IEEE 802.3 specification, rx_datak is driven high. If the received 10-bit code group is a data code group (/Dx.y/), rx_datak is driven low.
