DATASHEET
This register control the values transmitted by the PHY to the remote partner when advertising its
abilities
NP - Next Page
A ‘1’ indicates the PHY wishes to exchange Next Page information.
ACK - Acknowledge
It is used by the Auto-negotiation function to indicate that a device has successfully received its Link
Partner’s Link code Word.
RF - Remote Fault
When set, an advertisement frame will be sent with the corresponding bit set. This in turn will cause
the PHY receiving it to set the Remote Fault bit in its Status register
T4 - 100BASE-T4
A '1' indicates the PHY is capable of 100BASE-T4
TX_FDX - 100BASE-TX Full Duplex Capable
A '1' indicates the PHY is capable of 100BASE-TX Full Duplex
TX_HDX - 100BASE-TX Half Duplex Capable
A '1' indicates the PHY is capable of 100BASE-TX Half Duplex
10_FDX - 10BASE-T Full Duplex Capable
A '1' indicates the PHY is capable of 10BASE-T Full Duplex
10_HDX - 10BASE-T Half Duplex Capable
A '1' indicates the PHY is capable of 10BASE-T Half Duplex
The management entity sets the value of this field prior to AutoNegotiation.
‘1’ in these bit indicates that the mode of operation that corresponds to these will be acceptable to be
auto-negotiated to. Only modes supported by the PHY can be set.
CSMA
A '1' indicates the PHY is capable of 802.3 CSMA Operation
