Table 101. Auto-Negotiation Expansion ($ Port Index + 0x66)

Bit	Name	Description		Type1	Default
31:6	Reserved	Reserved		RO	0
		This register bit indicates the status of the auto-
		negotiation variable, base page. It flags
		synchronization with the auto-negotiation state
5	Base Page	diagram allowing detection of interrupted links.		RO	0
		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
4	Parallel Detection	0 = Parallel detection fault has not occurred		RO	0
	Fault	1 = Parallel detection fault has occurred
3	Link Partner Next Page	0 = Link partner is not Next Page able		RO	0
	Able	1 = Link partner is Next Page able
2	Next Page Able	0 = Local device is not Next Page able		RO	0
		1 = Local device is Next Page able
		Indicates that a new page has been received and
		the received code word has been loaded into
1	Page Received	Register 5 (base pages) or Register 8 (next pages)		RO	0
		as specified in the EEE 802.3 Standard.
		This bit clears on Read.
0	Link Partner Auto-	0 = Link partner is not auto-negotiation able		RO	0
	Negotiation Able	1 = Link partner is auto-negotiation able
1. RO = Read Only; RR = Clear on Read; W = Write; R/W = Read/Write
