Description
Bit 15 of the Link Partner Received Next Page Register
returns a 1 when the link partner has indicated that more
Next Pages are to be sent. This bit returns a 0 when the
link partner has indicated that this is the last Next Page to
be transmitted.
• 1 = Additional Next Pages follow.
• 0 = Sending last Next Page.
Bit 14 returns a 1 to indicate that the link partner has
received and acknowledged a Next Page. The bit returns
a 0 until the link partner has acknowledged the page.
• 1 = Acknowledge.
• 0 = No acknowledge.
Bit 13 of the Link Partner Received Next Page Register
returns a 1 to indicate that the link partner has sent a
formatted message page. This bit returns a 0 when the
link partner has sent an unformatted page.
• 1 = Formatted page.
• 0 = Unformatted page.
Bit 12 of the Link Partner Received Next Page Register
returns a 1 when the link partner indicates that it can
comply with the Next Page request. This bit returns a 0
when the link partner indicates that it cannot comply with
the Next Page request.
• 1 = Complies with message.
• 0 = Cannot comply with message.
The link partner toggles this bit between different Next
Page exchanges to insure a functional synchronization to
the BCM5722 Ethernet controller. Toggles between
exchanges of different Next Pages.
These 11 bits make up the message code defined IEEE
802.3, Section 28, Annex C, when the link partner has
sent a formatted page. When the link partner has sent
unformatted Next Pages, these 11 bits contain an
arbitrary data value.
