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 this bit based on the
incoming FLP bursts. Software should not attempt 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 message.
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.
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 IEEE 802.3u Annex 28C of Clause 28. Otherwise, the code shall be
interpreted as an Unformatted Page, and the interpretation is application specific.
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.
0 = Link Code Word has not been received.
