needs to exchange more information with the link partner. The PHY defaults to sending only a NULL
message page to the link partner unless the STA overrides the values in the register. Next pages will be
transmitted until the link partner has no more pages to transmit and bit 7.15 has been cleared by the STA.

Message/Unformatted Code Field
Freescale Semiconductor
RESET:
W
Indicates whether the link partner has A/N capabilities.
ACK2 is used to indicate that the receiver is able to act on the information (or perform the task) defined
in the message.
Message code field — Predefined code fields defined in IEEE 802.3u-1995 Annex 28C
Unformatted code field — Eleven bit field containing an arbitrary value
R
1 = Link partner is A/N able
0 = Link partner is not A/N able
1 = Additional next pages will follow
0 = Last page to transmit
1 = Message page
0 = Unformatted page
1 = Receiver is able to perform the task defined in the message
0 = Receiver is unable to perform the task defined in the message
1 = Previous value of the transmitted link code word equalled 0
0 = Previous value of the transmitted link code word equalled 1
