Table 548: 100Base-X Receive Error Counter (Address 18D, 12H) - Broadcom BCM5722 Programmer's Manual

BCM5722
Remote Fault
The PHY returns a 1 while its link partner is signaling 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.
Transmit Error Detected
The PHY returns 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 returns a 0.
Lock Error Detected
The PHY returns a 1 in bit 1 if the descrambler has lost lock since the last time this register was read. Otherwise, it returns a 0.
MLT3 Code Error Detected
The PHY returns 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 returns a 0.
100BASE-X Receive Error Counter
Bit Name
15:0 Receive Error Counter [15:0]
Receive Error Counter [15:0]
This counter increments each time the PHY receives a non-collision packet containing at least one receive error. The counter
automatically clears itself when read. When the counter reaches its maximum value, FFh, it stops counting receive errors
until cleared.
