Transmit Jabber Time Out
It is set to indicate that the transmitted frame is truncated due to more than 2048
bytes are transmitted
Loss of Carrier
It is set to indicate the loss of carrier during the frame transmission. It is not valid in
internal loopback mode
No Carrier
It is set to indicate that there is no carrier signal during the frame transmission. It is
not valid in internal loopback mode
Late Collision
It is set when a collision occurs after the collision window of 64 bytes
Collision Packet
It is set to indicate that the collision occurs during transmission
Excessive Collision
It is set to indicate that the transmission is aborted due to 16 excessive collisions
Reserved
Reserved
Transmit Jabber Disable
When set, the transmit Jabber Timer (2048 bytes) is disabled. Otherwise it is
Enable
Excessive Collision Mode Control : 0:aborts this packet when excessive collision
