describes the definition for the ANNPT register.
AN Next Page Transmit Register (ANNPT)
—
Reserved, should be cleared.
Next page able. This bit is read-only and returns 1 on read. While read as set, indicates local device supports
next page function.
Page received. This bit is read-only. The bit clears on a read to the register.
0 Normal operation.
1 A new page was received and stored in the applicable AN link partner ability or AN next page register. This
bit latches high in order for software to detect while polling.
Reserved, should be cleared.

Msg
Next page indication. [Reference MII bit 7.15 in IEEE 802.3, 2000 Edition Clause 28.2.4]
0 Last page.
1 Additional next pages to follow.
Reserved. (Ignore on read)
Message page. [Reference MII bit 7.13]
0 Unformatted page.
1 Message page.
Acknowledge 2. Used by the next page function to indicate that the device has the ability to comply
with the message. [Reference MII bit 7.12]
0 The local device cannot comply with message.
1 The local device complies with message.
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.
[Reference MII bit 7.11] 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. [Reference MII field
7.10:0]
