Receive Control Register
| LOOP | Internal Loopback 0 (LOOP_0): Loopback disabled. 1 (LOOP_1): Transmitted frames are looped back internal to the device and transmit MII output signals are not asserted. DRT must be cleared. |
| DRT | Disable Receive On Transmit 0 (DRT_0): Receive path operates independently of transmit (i.e., full-duplex mode). Can also be used to monitor transmit activity in half-duplex mode. 1 (DRT_1): Disable reception of frames while transmitting. (Normally used for half-duplex mode.) |
| MII_MODE | Media Independent Interface Mode 1 (MII_MODE_1): MII or RMII mode, as indicated by the RMII_MODE field. |
| PROM | Promiscuous Mode 0 (PROM_0): Disabled. 1 (PROM_1): Enabled. |
| BC_REJ | Broadcast Frame Reject |
| FCE | Flow Control Enable |
| RMII_MODE | RMII Mode Enable 0 (RMII_MODE_0): MAC configured for MII mode. 1 (RMII_MODE_1): MAC configured for RMII operation. |
| RMII_10T | Enables 10-Mbit/s mode of the RMII . 0 (RMII_10T_0): 100-Mbit/s operation. 1 (RMII_10T_1): 10-Mbit/s operation. |
| PADEN | Enable Frame Padding Remove On Receive 0 (PADEN_0): No padding is removed on receive by the MAC. 1 (PADEN_1): Padding is removed from received frames. |
| PAUFWD | Terminate/Forward Pause Frames 0 (PAUFWD_0): Pause frames are terminated and discarded in the MAC. 1 (PAUFWD_1): Pause frames are forwarded to the user application. |
| CRCFWD | Terminate/Forward Received CRC 0 (CRCFWD_0): The CRC field of received frames is transmitted to the user application. 1 (CRCFWD_1): The CRC field is stripped from the frame. |
| CFEN | MAC Control Frame Enable 0 (CFEN_0): MAC control frames with any opcode other than 0x0001 (pause frame) are accepted and forwarded to the client interface. 1 (CFEN_1): MAC control frames with any opcode other than 0x0001 (pause frame) are silently discarded. |
| MAX_FL | Maximum Frame Length |
| NLC | Payload Length Check Disable 0 (NLC_0): The payload length check is disabled. 1 (NLC_1): The core checks the frame’s payload length with the frame length/type field. Errors are indicated in the EIR[PLR] field. |
| GRS | Graceful Receive Stopped |
