The PHY returns a 1 in bit 11, when the SMII receive FIFO encounters an overrun or underrun condition. Locked. The PHY returns a 1 in bit 9 when the de-scrambler is locked to the incoming data stream. Otherwise, it returns a 0. Current 100BASE-X Link Status. The PHY returns a 1 in bit 8 when the 100BASE-X link status is good. Otherwise, it returns a 0. Remote Fault. The PHY returns a 1 while its link partner is signalling a far-end fault condition. Otherwise, it returns a 0. False Carrier Detected. The PHY returns a 1 in bit 5 of the extended status register if a false carrier has been detected since the last time this register was read. Otherwise, it returns a 0. Bad ESD Detected. The PHY returns a 1 in bit 4 if an end-of-stream delimiter error has been detected since the last time this register was read. Otherwise, it returns a 0. Receive Error Detected. The PHY returns a 1 in bit 3 if a packet was received with an invalid code since the last time this register was read. Otherwise, it returns a 0. Table 27: 100BASE-X Auxiliary Status Register (Address 17d, 11h) Bit Name R/W Description Default 15:12 Reserveda a. When writing to this register, preserve existing values of reserved bits by completing a Read/Modify Write. –– 0 11 SMII Overrun/Underrun Detected RO 1 = Error detected 0 = No error 0 10 Reserveda –– PIN 9 Locked RO 1 = Descrambler locked 0 = Descrambler unlocked 0 8 Current 100BASE-X Link Status RO 1 = Link pass 0 = Link fail 0 7 Remote Fault RO 1 = Remote fault detected 0 = No remote fault detected 0 6 Reserveda –– 0 5 False Carrier Detected RO LH 1 = False carrier detected since last read 0 = No false carrier since last read 0 4 Bad ESD Detected RO LH 1 = ESD error detected since last read 0 = No ESD error since last read 0 3 Receive Error Detected RO LH 1 = Receive error detected since last read 0 = No receive error since last read 0 2 Transmit Error Detected RO LH 1 = Transmit error code received since last read 0 = No transmit error code received since last read 0 1 Lock Error Detected RO LH 1 = Lock error detected since last read 0 = No lock error since last read 0 0 MLT3 Code Error Detected RO LH 1 = MLT3 code error detected since last read 0 = No MLT3 code error since last read 0 Note: R/W = Read/Write, RO = Read only, SC = Self Clear, LL = Latched Low, LH = Latched High, LL and LH Clear after read operation. Use default values of reserved bit(s) when writing to reserved bit(s). |
