DP83816 4.0 Register Set (Continued) Bit Bit Name 9 T4 8 TX_FD 7 TX 6 10_FD 5 10 4:0 Selector Description 100BASE-T4 Support: Default: 0/ RO 1= 100BASE-T4 is supported by the local device 0 = 100BASE-T4 not supported 100BASE-TX Full Duplex Support: Default: dependent on setting of the ANEG_SEL in the CFG register 1 = 100BASE-TX Full Duplex is supported by the local device 0 = 100BASE-TX Full Duplex not supported 100BASE-TX Support: Default: dependent on the setting of the ANEG_SEL bits in the CFG register 1 = 100BASE-TX is supported by the local device 0 = 100BASE-TX not supported 10BASE-T Full Duplex Support: Default: dependent on setting of the ANEG_SEL in the CFG register 1 = 10BASE-T Full Duplex is supported by the local device 0 = 10BASE-T Full Duplex not supported 10BASE-T Support: Default: dependent on the setting of the ANEG_SEL bits in the CFG register 1 = 10BASE-T is supported by the local device 0 = 10BASE-T not supported Protocol Selection Bits: Default: <00001> These bits contain the binary encoded protocol selector supported by this port. <00001> indicates that this device supports IEEE 802.3u. 4.3.6 Auto-Negotiation Link Partner Ability Register This register contains the advertised abilities of the Link Partner as received during Auto-Negotiation. The content changes after the successful auto-negotiation if Next-pages are supported. Tag: ANLPAR Offset: 0094h Bit Bit Name 15 NP 14 ACK 13 RF 12:10 Reserved 9 T4 8 TX_FD 7 TX 6 10_FD Size: 16 bits Hard Reset: 0000h Access: Read Only Description Next Page Indication: 0 = Link Partner does not desire Next Page Transfer 1 = Link Partner desires Next Page Transfer Acknowledge: 1 = Link Partner acknowledges reception of the ability data word 0 = Not acknowledged The Device's Auto-Negotiation state machine will automatically control this bit based on the incoming FLP bursts. Remote Fault: 1 = Remote Fault indicated by Link Partner 0 = No Remote Fault indicated by Link Partner Reserved for Future IEEE use: Write as 0, read as 0 100BASE-T4 Support: 1 = 100BASE-T4 is supported by the Link Partner 0 = 100BASE-T4 not supported by the Link Partner 100BASE-TX Full Duplex Support: 1 = 100BASE-TX Full Duplex is supported by the Link Partner 0 = 100BASE-TX Full Duplex not supported by the Link Partner 100BASE-TX Support: 1 = 100BASE-TX is supported by the Link Partner 0 = 100BASE-TX not supported by the Link Partner 10BASE-T Full Duplex Support: 1 = 10BASE-T Full Duplex is supported by the Link Partner 0 = 10BASE-T Full Duplex not supported by the Link Partner 69 www.national.com
