85 / 92 page ![]() Intel ® LXT972M Single-Port 10/100 Mbps PHY Transceiver Datasheet 85 Document Number: 302875-005 Revision Date: 27-Oct-2005 Table 52 lists register #2 status bits. Table 52. Status Register #2 - Address 17, Hex 11 Bit Name Description Type 1 Default 17.15 Reserved Always 0. RO 0 17.14 10/100 Mode 0 = LXT972M Transceiver is not operating 100BASE-TX mode. 1 = LXT972M Transceiver is operating in 100BASE-TX mode. RO 0 17.13 Transmit Status 0 = LXT972M Transceiver is not transmitting a packet. 1 = LXT972M Transceiver is transmitting a packet. RO 0 17.12 Receive Status 0 = LXT972M Transceiver is not receiving a packet. 1 = LXT972M Transceiver is receiving a packet. RO 0 17.11 Collision Status 0 = No collision. 1 = Collision is occurring. RO 0 17.10 Link 0 = Link is down. 1 = Link is up. RO 0 17.9 Duplex Mode 0 = Half-duplex. 1 = Full-duplex. RO 0 17.8 Auto-Negotiation 0 = LXT972M Transceiver is in manual mode. 1 = LXT972M Transceiver is in auto-negotiation mode. RO 0 17.7 Auto-Negotiation Complete 0 = Auto-negotiation process not completed. 1 = Auto-negotiation process completed. This bit is valid only when auto negotiate is enabled. The value is equivalent to the value of Register bit 1.5. RO 0 17.6 Reserved Always 0. RO 0 17.5 Polarity 0 = Polarity is not reversed. 1 = Polarity is reversed. NOTE: Polarity is not a valid status in 100 Mbps mode. RO 0 17.4 Pause 0 = The LXT972M Transceiver is not Pause capable. 1 = The LXT972M Transceiver is Pause capable. R0 17:3 Error 0 = No error occurred 1 = Error occurred (Remote Fault, jabber, parallel detect fault) NOTE: The register bit is cleared when the registers that generate the error condition are read. RO 0 17:2 Reserved Always 0. RO 0 17:1 Reserved Always 0. RO 0 17.0 Reserved Always 0. RO 0 1. RO = Read Only. R/W = Read/Write |
