Ethernet Controller (ENET)
26.1 Overview
The ethernet controller (ENET) consists of two MACs (media access controllers), each with
it's own dedicated uDMA (unified DMA) module. The MAC module is third party IP from
"More Than IP" (MTIP). The MACs interface to 10 Mbps and 100 Mbps Ethernet/IEEE
802.3™ networks. For Ethernet, an external PHY or SerDes device is required to complete
the interface to the media. Each MAC supports multiple standard media-independent
interfaces. An integrated 3-Port Switch allows the macs to filter and forward traffic at
wire-speed to each other or the core, or operate as two independent ports.
The ENET assembly provides two master ports on the AHB Bus. IP provides interface for
connecting various FIFOs for data storage (for MAC and Switch).
The ENET MAC is backward compatible with the Freescale FEC controller (Such as the
FEC used in i.MX25).
