Toggle. Used to ensure synchronization with the link partner during next page exchange. This bit
always takes the opposite value of the toggle bit of the previously-exchanged link code word. The
initial value in the first next page transmitted is the inverse of bit 11 in the base link code word.
This bit is read-only.
0 Toggle bit of the previously-exchanged link code word was 1.
1 Toggle bit of the previously-exchanged link code word was 0.
Message pages are formatted pages that carry a pre-defined message code, which is
enumerated in IEEE 802.3u/Annex 28C. Unformatted code fields take on an arbitrary value.
