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.
