D08 R RXCV 0 Receive packet has code violation
Set to 1 to indicate that the Ethernet PHY asserted
the RXER signal during the data phase of this
frame. RXCV indicates that the PHY encountered
invalid receive codes while receiving the data.
When this bit is set, the RXREGR and RXFIFOH bits
in the Ethernet General Status register remain
inactive. The bad receive packet is flushed
immediately from the FIFO.
D07 R RXLNG 0 Receive packet is too long
Set to 1 to indicate that the next packet in the
receive FIFO is longer than 1518 bits. A long
packet is accepted only when the ERXLNG bit is
set in the Ethernet General Control register.
When this bit is set, the RXREGR and RXFIFOH bits
in the Ethernet General Status register remain
inactive. The bad receive packet is flushed
immediately from the FIFO.
D06 R RXSHT 0 Receive packet is too short
Set to 1 to indicate that the next packet in the
receive FIFO is smaller than 64 bytes. A short
packet is accepted only when the ERXSHT bit is
set in the Ethernet General Control register.
When this bit is set, the RXREGR and RXFIFOH bits
in the Ethernet General Status register remain
inactive. The bad receive packet is flushed
immediately from the FIFO.
