Description
Multicast Address Received:
This bit set to 1 indicates that a multicast
packet is received.
Physical Address Matched:
This bit set to 1 indicates that the destination
address of this packet matches the value written in ID registers.
Broadcast Address Received:
This bit set to 1 indicates that a broadcast
packet is received. BAR, MAR bit will not be set simultaneously.
Reserved
Invalid Symbol Error:
(100BASE-TX only) This bit set to 1 indicates
that an invalid symbol was encountered during the reception of this packet.

This bit set to 1 indicates that the received packet
length is smaller than 64 bytes ( i.e. media header + data + CRC < 64
bytes )
Long Packet:
This bit set to 1 indicates that the size of the received
packet exceeds 4k bytes.
CRC Error:
When set, indicates that a CRC error occurred on the
received packet.
