7.1.9 Auto-Negotiation Next Page Transmit Register (ANNPTR)
This register contains the next page information sent by this device to its Link Partner during Auto-Negotiation.
0
LP_AN_ABLE
0, RO
Link Partner Auto-Negotiation Able:
1 = indicates that the Link Partner supports Auto-Negotiation.
0 = indicates that the Link Partner does not support Auto-Negotia-
tion.

NP
0, RW
Next Page Indication:
0 = No other Next Page Transfer desired.
1 = Another Next Page desired.

RESERVED
0, RO
RESERVED: Writes ignored, read as 0.

MP
1, RW
Message Page:
1 = Message Page.
0 = Unformatted Page.
12
ACK2
0, RW
Acknowledge2:
1 = Will comply with message.
0 = Cannot comply with message.
Acknowledge2 is used by the next page function to indicate that Lo-
cal Device has the ability to comply with the message received.

TOG_TX
0, RO
Toggle:
1 = Value of toggle bit in previously transmitted Link Code Word
was 0.
0 = Value of toggle bit in previously transmitted Link Code Word
was 1.
Toggle is used by the Arbitration function within Auto-Negotiation
to ensure synchronization with the Link Partner during Next Page
exchange. This bit shall always take the opposite value of the Tog-
gle bit in the previously exchanged Link Code Word.

This field represents the code field of the next page transmission.
If the MP bit is set (bit 13 of this register), then the code shall be
interpreted as a "Message Page”, as defined in annex 28C of IEEE
802.3u. Otherwise, the code shall be interpreted as an "Unformat-
ted Page”, and the interpretation is application specific.
The default value of the CODE represents a Null Page as defined
in Annex 28C of IEEE 802.3u.
