CSMA Block
The CSMA/CD block is first interfaced via its control registers in order to define its operational
configuration. From then on, the DMA interface between the CSMA/CD block and memory is used to
transfer data to and from its data path interface.
For transmit, the CSMA/CD block will be asked to transmit frames as soon as they are ready in memory. It
will continue transmissions until any of the following transmit error occurs:
1.
2.
3.
4.
In that case TXENA will be cleared and the CPU should restart the transmission by setting it again. If a
transmission is successful, TXENA stays set and the CSMA/CD is provided by the DMA block with the
next packet to be transmitted.
