Two-bit wide port disables 8B/10B encoder on a per-byte basis. High-order bit affects
high-order byte of data path.
Two-bit wide ports control disparity of outgoing 8B/10B data. High-order bit affects
high-order byte of data path.
Two-bit wide port flags invalid K character codes as they are encountered. High-order
bit corresponds to high-order byte of data path.
Two-bit wide port indicates current running disparity of the 8B/10B encoder on a per-
byte basis. High-order bit affects high-order byte of data path.
Two-bit wide port flags valid 8B/10B comma characters as they are encountered. High-
order bit corresponds to high-order byte of data path.
Two-bit wide port flags valid 8B/10B K characters as they are encountered. High-order
bit corresponds to high-order byte of data path.
Two-bit wide port indicates current running disparity of the 8B/10B decoder on a per-
byte basis. High-order bit corresponds to high-order byte of data path.
