NP
0, RO
Next Page Indication:
1 = Link Partner desires Next Page Transfer.
0 = Link Partner does not desire Next Page Transfer.
14
ACK
0, RO
Acknowledge:
1 = Link Partner acknowledges reception of the ability data word.

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.
