17. Ethernet Media Access Controller
The hard processor system (HPS) provides three Ethernet media access controller (EMAC) peripherals. Each EMAC can be used to transmit and receive data at 10/100/1000 Mbps over Ethernet connections in compliance with the IEEE 802.3 specification. The EMACs are instances of the Synopsys* DesignWare* Universal 10/100/1000 Ethernet MAC (version 3.74a).
The EMAC has an extensive memory-mapped control and status register (CSR) set, which can be accessed by the Arm* Cortex*-A53.
For an understanding of this chapter, be familiar with the basics of IEEE 802.3 media access control (MAC). 43
