This bit indicates the status of the auto-negotiation
variable, Base Page. It also flags synchronization
with the auto-negotiation state diagram, allowing
detection of interrupted links. This bit is only used if
Register bit 16.1 (Alternate Next Page feature) is
set.
1 = base_page = true
0 = base_page = false
1 = Parallel Detection Fault has occurred.
0 = Parallel Detection Fault has not occurred.
1 = Link partner is Next Page able.
0 = Link partner is not Next Page able.
1 = Local device is Next Page able
0 = Local device is not Next Page able
Indicates that a new page has been received and
the received code word has been loaded into
Register 5 (Base Pages) or Register 8 (Next
Pages) as specified in clause 28 of IEEE 802.3.
This bit is cleared on read. If Register bit 16.1 is set,
the Page Received bit is also cleared when
mr_page_rx = false, or transmit_disable = true.
1 = Link partner is auto-negotiation able.
0 = Link partner is not auto-negotiation able.
1 = Additional Next Pages follow
0 = Last page
Write as 0, ignore on read
1 = Message Page
0 = Unformatted page
