Next Page Indication:
1 = Link Partner desires Next Page Transfer.
0 = Link Partner does not desire Next Page Transfer.
Acknowledge:
1 = Link Partner acknowledges reception of the ability data word.
0 = Not acknowledged.
The Auto-Negotiation state machine will automatically control the
this bit based on the incoming FLP bursts. Software should not at-
tempt to write to this bit.
Message Page:
1 = Message Page.
0 = Unformatted Page.
Acknowledge 2:
1 = Link Partner does have the ability to comply to next page mes-
sage.
0 = Link Partner does not have the ability to comply to next page
message.
Toggle:
1 = Previous value of the transmitted Link Code word equalled 0.
0 = Previous value of the transmitted Link Code word equalled 1.
Code:
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
Clause 28. Otherwise, the code shall be interpreted as an “Unfor-
matted Page,” and the interpretation is application specific.
RESERVED: Writes ignored, Read as 0.
Parallel Detection Fault:
1 = A fault has been detected via the Parallel Detection function.
0 = A fault has not been detected.
Link Partner Next Page Able:
1 = Link Partner does support Next Page.
0 = Link Partner does not support Next Page.
Next Page Able:
1 = Indicates local device is able to send additional “Next Pages”.
Link Code Word Page Received:
1 = Link Code Word has been received, cleared on a read.
