Description
Technology Ability Field[1]
When set, indicates that the PHY supports the 10Base-T Full-Duplex
signaling protocol. If software wants to ensure that this mode is not used,
this bit can be written to 0 and Auto-Negotiation re-initiated.
Technology Ability Field[0]
When set, indicates that the PHY supports the 10Base-T half-duplex
signaling protocol. If software wants to ensure that this mode is not used,
this bit can be written to 0 and Auto-Negotiation re-initiated.
Selector Field
The S[4:0] field encodes 32 possible messages for communicating
between PHYs. This field is hard-coded to 0x01, indicating that the
Stellaris^® PHY is IEEE 802.3 compliant.
