BIT DESCRIPTION
Reserved for future use.
PHY Duplex Polarity. If PhyDuplexPolarity is a logic 0, the duplex
status signal between the PHY and the MAC is active low.
PHY Duplex Status. If PhyDuplexStatus is a logic 1, the PHY is
operating in full duplex mode. If PhyDuplexStatus is a logic 0, the
PHY is operating in half duplex mode.
PHY Speed Status. PhySpeedStatus provides a real-time indication
of the IP100’s PHY speed. If PhySpeedStatus is a logic 1, the
IP100’s PHY is operating at 100Mbps operation. If PhySpeedStatus
is a logic 0, the IP100’s PHY is operating at 10Mbps operation.
PHY Link Status. PhyLinkStatus provides a real-time indication of
the IP100’s PHY link state. If PhyLinkStatus is a logic 1, the IP100’s
PHY link is up. If PhyLinkStatus is a logic 0, the IP100’s PHY link is
down.

BIT DESCRIPTION
Receive Unicast. If ReceiveUnicast is a logic 1, the IP100 receives
unicast frames (frames where the DA field matches the 48-bit value
in the StationAddress register.
Receive Multicast. If ReceiveMulticast is a logic 1, the IP100
receives all multicast frames, including broadcast frames.
Receive Broadcast. If ReceiveBroadcast is a logic 1, the IP100
receives all broadcast frames.
Receive All Frames. If ReceiveAllFrames is a logic 1, the IP100
receives all frames.
Receive Multicast Hash. If ReceiveMulticastHash is a logic 1, the
IP100 receives all which pass the hash filtering mechanism defined
in the HashTable register..
Receive IP Multicast. If ReceiveIPMulticast is a logic 1, the IP100
receives all multicast IP datagrams, which are mapped into Ethernet
multicast frames with destination address of 01:00:5e:xx:xx:xx as
defined in RFC 1112 and RFC 1700. The first 3 bytes require exact
match, and the last 3 bytes are ignored.
