This set of buses is intended to be used to keep track of sync header errors. There is a pair of outputs for each PCS Lane. The STAT_RX_FRAMING_ERR_[0-19] output bus indicates how many sync header errors were received and it is qualified (that is, the value is only valid) when the corresponding STAT_RX_FRAMING_ERR_VALID[0-19] is sampled as a 1.
