Transmit Control Register
| GTS | Graceful transmit stop |
| FDEN | Full duplex enable |
| TFC_PAUSE | Transmit frame control pause 0 (0): No PAUSE frame transmitted. 1 (1): The MAC stops transmission of data frames after the current transmission is complete. |
| RFC_PAUSE | Receive frame control pause |
| ADDSEL | Source MAC address select on transmit 0 (000): Node MAC address programmed on PADDR1/2 registers. |
| ADDINS | Set MAC address on transmit 0 (0): The source MAC address is not modified by the MAC. 1 (1): The MAC overwrites the source MAC address with the programmed MAC address according to ADDSEL. |
| CRCFWD | Forward frame from application with CRC 0 (0): TxBD[TC] controls whether the frame has a CRC from the application 1 (1): The transmitter does not append any CRC to transmitted frames as it is expecting a frame with CRC from the application. |
