100BASE-TX Half Duplex
This bit will be set to 1 upon reset and is writeable. Writing to
this register has no effect until auto-negotiation is re-initiated.
10BASE-T Full Duplex
This bit will be set to 1 upon reset and is writeable. Writing to
this register has no effect until auto-negotiation is re-initiated.
10BASE-T
This bit will be set to 1 upon reset and is writeable. Writing to
this register has no effect until auto-negotiation is re-initiated.
Protocol Selector Field
The value is 00001 for IEEE 802.3.
Next Page
When 1 is read, it indicates the link partner wishes to engage in
Next Page exchange.
Acknowledge
When 1 is read, it indicates the link partner has successfully
received at least 3 consecutive and consistent FLP bursts.
Remote Fault
When 1 is read, it indicates the link partner has a fault.
Technology Ability Field
This field contains the technology ability of the link partner.
The bit definition is the same as MR4.12:5.
Selector Field
This field contains the type of message sent by the link partner.
For IEEE 802.3 compliant link partner, this field should be
00001.
Reserved
Parallel Detection Fault
When 1 is read, it indicates that more than one technology has
been detected during link up. This bit is cleared when read.
Link Partner Next Page Able
When 1 is read, it indicates the link partner supports the Next
Page function.
Next Page Able
Reads 0 since the 78Q8430 PHY does not support the Next
Page function.
Page Received
Reads 1 when a new link code word has been received into the
Auto-negotiation Link Partner Ability Register. This bit is
cleared upon read.
Link Partner Auto-negotiation Able
When 1 is read, it indicates the link partner is able to participate
in the Auto-Negotiation function.
