n BCM5208
BAD ESD DETECTED. The PHY will return 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 will return a “0”.
RECEIVE ERROR DETECTED. The PHY will return a “1” in bit 3 if a packet was received with an invalid code since the
last time this register was read. Otherwise it will return a “0”.
TRANSMIT ERROR DETECTED. The PHY will return a “1” in bit 2 if a packet was received with a transmit error code since
the last time this register was read. Otherwise it will return a “0”.
LOCK ERROR DETECTED. The PHY will return a “1” in bit 1 if the de-scrambler has lost lock since the last time this
register was read. Otherwise it will return a “0”.
MLT3 CODE ERROR DETECTED. The PHY will return a “1” in bit “0” if an MLT3 coding error has been detected in the
receive data stream since the last time this register was read. Otherwise it will return a “0”. ..
100BASE-X RECEIVE ERROR COUNTER
The 100BASE-X receive error counter will increment each time the BCM5208 receives a non-collision packet containing
at least one receive error. The counter will automatically clear itself when read. When the counter reaches its maximum
value, FFh, it stops counting Receive Errors until cleared. See Table 16 for the bit descriptions.
100BASE-X FALSE CARRIER SENSE COUNTER
The 100BASE-X false carrier sense counter will increment each time the BCM5208 detects a false carrier on the receive
input. The counter will automatically clear itself when read. When the counter reaches its maximum value, FFh, it stops
counting False Carrier Sense Errors until cleared. See Table 17 for the bit descriptions.
100BASE-X DISCONNECT COUNTER
The 100BASE-X disconnect counter will increment each time the carrier integrity monitor within the BCM5208 enters the
“link unstable” state. The counter will automatically clear itself when read. When the counter reaches its maximum value,
FFh, it stops counting Disconnects until cleared. See Table 18 for the bit descriptions.
