2.4 microseconds after the ready signal was asserted. This occurs
when reading an empty buffer.
Indicates that the DX-LAN hardware receive buffer became full and
had to reject a packet for lack of space.
Indicates that a packet was received with a CRC error. This usually
means that a collision has corrupted the packet.
Indicates that a <169>runt<170> packet (one less than 15 bytes in
length) was received. This usually occurs after a collision has
truncated the original length.
