Register Name:
Access Type:
• SPD: Speed
Set to 1 to indicate 100 Mbit/s operation, 0 for 10 Mbit/s. The value of this pin is reflected on the speed pin.
• FD: Full Duplex
If set to 1, the transmit block ignores the state of collision and carrier sense and allows receive while transmitting. Also con-
trols the half_duplex pin.
• Bit rate:
If set to 1 to configure the interface for serial operation. Must be set before receive and transmit enable in the network con-
trol register. If set a serial interface is configured with transmit and receive data being driven out on txd[0] and received on
rxd[0] serially. Also the crs and rx_dv are logically ORed together so either may be used as the data valid signal.
• CAF: Copy All Frames
When set to 1, all valid frames are received.
• JFRAME: Jumbo Frames
Set to one to enable jumbo frames of up to 10240 bytes to be accepted.
• NBC: No Broadcast
When set to 1, frames addressed to the broadcast address of all ones are not received.
• MTI: Multicast Hash Enable
When set, multicast frames are received when the 6-bit hash function of the destination address points to a bit that is set in
the hash register.
• UNI: Unicast Hash Enable
When set, unicast frames are received when the 6-bit hash function of the destination address points to a bit that is set in
the hash register.
• BIG: Receive 1536 bytes frames
Setting this bit means the MACB receives frames up to 1536 bytes in length. Normally, the MACB would reject any frame
above 1518 bytes.
• EAE: External address match enable
When set, the eam pin can be used to copy frames to memory.
