Acknowledge2:
1 = Will comply with message
0 = Cannot comply with message
Acknowledge2 is used by the next page function to indicate that
Local Device has the ability to comply with the message received.

Toggle
RO
0
Toggle:
1 = Toggle bit in previously transmitted Link Code Word was 0
0 = Toggle bit in previously transmitted Link Code Word was 1
Toggle is used by the Arbiitration function within Auto-Negotiation to
synchronize with the Link Parnter during Next Page exchange. This
bit always takes the opposite value of the Toggle bit in the previously
exchanged Link Code Word.

0001
This field represents the code field of the next page transmission. If
the Message Page bit is set (bit [13] of this register), then the code is
interpreted as a Message Page, as defined in annex 28C of IEEE
802.3u. Otherwise, the code is interperated as an Unformatted 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.
