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.
5.
Collisions on same frame
Late collision
Lost Carrier sense and MON_CSN set
Transmit Underrun
SQET error and STP_SQET set
