Bit 4 – CAF Copy All Frames

When writing a '1' to this bit, all valid frames will be accepted.

Bit 3 – JFRAME Jumbo Frame Size

riting a '1' to this bit enables jumbo frames of up to 10240 bytes to be accepted. The default length is 10240 bytes.

Bit 2 – DNVLAN Discard Non-VLAN Frames

Writing a '1' to this bit allows only VLAN-tagged frames to pass to the address matching logic.

Writing a '0' to this bit allows both VLAN_tagged and untagged frames to pass to the address matching logic.

Bit 1 – FD Full Duplex

Writing a '1' enables full duplex operation, so the transmit block ignores the state of collision and carrier sense and

allows receive while transmitting.

Writing a '0' disables full duplex operation.

Bit 0 – SPD Speed

Writing a '1' selects 100Mbps operation.

Writing a '0' to this bit selects 10Mbps operation.
