ENET_RCR field descriptions (continued)

MAC control frame enable

Description

Enables/disables the MAC control frame.

0 MAC control frames with any opcode other than 0x0001 are accepted and forwarded to the client

interface.

1 MAC control frames with any opcode other than 0x0001 (pause frame) are silently discarded.

Terminate/forward received CRC

Specifies whether the CRC field of received frames is transmitted or stripped.

NOTE: If padding function is enabled (PADEN = 1), CRCFWD is ignored and the CRC field is checked

and always terminated and removed.

0 The CRC field of received frames is transmitted to the user application.

1 The CRC field is stripped from the frame.

Terminate/forward pause frames.

Specifies whether pause frames are terminated or forwarded.

0 Pause frames are terminated and discarded in the MAC.

1 Pause frames are forwarded to the user application.

Enable frame padding remove on receive

Specifies whether the MAC removes padding from received frames.

0 No padding is removed on receive by the MAC.

1 Padding is removed from received frames.

This read-only field is reserved and always has the value zero.

Enables 10-Mbps mode of the RMII.

0 100 Mbps operation

1 10 Mbps operation

RMII mode enable

Specifies whether the MAC is configured for MII mode or RMII operation.

0 MAC configured for MII mode.

1 MAC configured for RMII operation.

This read-only field is reserved and always has the value zero.

This read-only field is reserved and always has the value zero.

Flow control enable

If set, the receiver detects PAUSE frames. Upon PAUSE frame detection, the transmitter stops

transmitting data frames for a given duration.

Broadcast frame reject
