... By the same token, CSMA/CD cycles might be postponed. The worst case CSMA/CD latency for arbiter service is one memory cycle. The arbiter uses the pointer register as the CPU provided address, and the internal DMA address from the CSMA/CD side as the addresses to be provided to the MMU.

... The read access time is 40ns and the cycle time is 185ns. If any one of them does not satisfy the application requirements, wait states should be added.

... When a CSMA/CD cycle begins, the arbiter will route the CSMA/CD DMA addresses to the MMU as well as the packet number associated with the operation in progress. In full-duplex mode, receive and transmit requests are alternated in such a way that the CPU arbitration cycle time is not affected. SMSC LAN91C96 5v&3v Page 81 DATASHEET ...

... Note that the CPU can enqueue a transmit command with a packet number that does not follow the sequence in which the MMU assigned packet numbers. For example, when a transmission failed and it is retried in software, or when a receive packet is modified and sent back to the network. SMSC LAN91C96 5v&3v Page 83 DATASHEET ...

... In that case TXENA will be cleared and the CPU should restart the transmission by setting it again transmission is successful, TXENA stays set and the CSMA/CD is provided by the DMA block with the next packet to be transmitted.
