The Message/Unformatted Code bits indicate the message code being transmitted to the Link Partner. The local PHY passes
the message code to the Link Partner without interpreting or reacting to it. By default, this code is set to “000 0000 0001”,
indicating a null message.
25.3.9 Register 8 (08h)–Auto-Negotiation Link Partner Next-Page Receive Register,Clause 28/37 View
SMI Register 8 contains the Link Partner’s Next-Page register contents. The contents of this register are only valid when the
Page Received bit (6.1)
8.15 – LP Next Page
This bit indicates if more pages follow from the Link Partner.
8.14 – LP Acknowledge
This bit returns a “1” when the Link Partner signals that it has received the Link Code Word from the local PHY. The local PHY
uses this bit for proper Link Code Word exchange, as defined in Clause 28 of IEEE 802.3.
8.13 – LP Message Page
The Message Page bit indicates if the page received from the Link Partner is a message page or an unformatted page.
8.12 – LP Acknowledge2
The Acknowledge2 bit indicates whether the Link Partner MAC reports that it is able to act on the information (or perform the
task) indicated in the message. The local PHY does not interpret or act on changes in the state of this bit.
8.11 – LP Toggle
The Toggle bit is used by the arbitration function in the local PHY to ensure synchronization with the Link Partner during Next-
Page exchanges. In the Link Partner, the Toggle bit is automatically set to the opposite state of the Toggle bit in the previously
exchanged Link Code Word from the Link Partner.
8.10:0 – LP Message/Unformatted Code
The Message/Unformatted Code bits indicate the message code being transmitted by the Link Partner.
