This bit indicates the status of the Auto-Negotiation variable, base page. It
flags synchronization with the Auto-Negotiation state diagram allowing
detection of interrupted links. This bit is only used if bit 16.1 (Alternate NP
feature) is set.
1 = basepage = true
0 = basepage = 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.
1 = 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 802.3. This bit is cleared on read. If 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
1 = Complies with message
0 = Can not comply with message
1 = Previous value of the transmitted Link Code Word equalled logic
zero
0 = Previous value of the transmitted Link Code Word equalled logic
