Description
Next Page
When set, this bit indicates that the link partner’s Ethernet Controller is
capable of Next page exchanges to provide more detailed information
on the Ethernet Controller’s capabilities.
Acknowledge
When set, this bit indicates that the Ethernet Controller has successfully
received the link partner’s advertised abilities during auto-negotiation.
Remote Fault
Used as a standard transport mechanism for transmitting simple fault
information from the link partner.
Technology Ability Field
The A[7:0] field encodes individual technologies that are supported
by the Ethernet Controller. See the MR4 register for definitions. Note
that bits 12:9 describe functions that are not implemented on the
Stellaris^® Ethernet Controller. Refer to the IEEE 802.3 standard for
definitions.
Selector Field
The S field encodes possible messages for communicating between
Ethernet Controllers.
