Base Page
This register 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 register bit is only used if Register bit 16.1
(alternate Next Page feature) is set.
0 = base_page = false
1 = base_page = true
