10/100 Non-PCI Ethernet Single Chip MAC + PHY

Datasheet

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
