Write as 0, ignore on read
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.
