Network IPs

IP Name Details
Ethernet 10/100 MAC Ethernet controller is compliant to IEEE802.3 and it provides interface between the host subsystem and the Media Independent Interface (MII). The 10/100 Ethernet MAC consists of DMA (TX DMA, RX DMA), TLI (TX buffer, RX buffer), 10/100 Ethernet controller. The DMA automates data transfers and frees the CPU from this task.
