Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Next Page
When set, indicates that the link partner’s PHY is capable of Next page
exchanges to provide more detailed information on the PHY’s
capabilities.
Acknowledge
When set, indicates that the device 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.
Technology Ability Field
The A field encodes individual technologies that are supported by the
PHY. See the MR4 register.
Selector Field
The S field encodes possible messages for communicating between
PHYs.
