25 / 54 page ![]() Preliminary Data Sheet AC101L 8/9/04 B roa dcom Co rpo rat ion Document AC101L-DS06-R TP PHY Register Summary Page 15 1.13 100BASE-TX Half-Duplex 1 = 100BASE-TX half-duplex capable. 0 = Not TX half-duplex capable. Default value: SPD100 && (ANEN || !DUPLEX). RO See description 1.12 10BASE-T Full-Duplex 1 = 10BASE-T full-duplex capable. 0 = Not 10BASE-T full-duplex capable. Default value: DUPLEX && (ANEN || !SPD100). RO See description 1.11 10BASE-T Half-Duplex 1 = 10BASE-T half-duplex capable. 0 = Not 10BASE-T half-duplex capable. Default value: ANEN || (!SPD100 && !DUPLEX). RO See description 1.[10:7] Reserved – RO 0000 1.6 MF Preamble Suppression The PHY is able to perform management transaction without MDIO preamble. The management interface needs a minimum of 32 bits of preamble after reset. RO 1 1.5 ANEN Complete 1 = Auto-negotiation process completed. Registers 4, 5, and 6 are valid after this bit is set. 0 = Auto-negotiation process is not completed. RO 0 1.4 Remote Fault 1 = Remote fault condition detected. 0 = No remote fault. This bit remains set until it is cleared by reading register 1. RO/LH 0 1.3 ANEN Ability 1 = Able to perform the auto-negotiation function; default value is determined by the ANEN pin. 0 = Unable to perform the auto-negotiation function. RO Set by ANEN 1.2 Link Status 1 = Link is established. If the link fails, this bit clears and remains at 0 until the register is read again. 0 = Link is down. RO/LL 0 1.1 Jabber Detect 1 = Jabber condition detected. 0 = No Jabber condition detected. RO/LH 0 1.0 Extended Capability 1 = Extended register capable. This bit is tied permanently to a value of 1. RO 1 Table 6: Register 1: Status Register (Cont.) Bit Name Description Mode Default |
