The management interface uses the industry standard AXI4-Lite to allow access to the Ethernet MAC core level. This interface is used for these operations:
- Configuring the MAC core
- Configuring the frame filter
- Configuring the interrupts
- Accessing statistics information
- Providing access to the MDIO interface to configure Ethernet PHY devices
Table 1 describes the optional signals used by you to access the Ethernet MAC core level.
The following figures show the basic AXI4-Lite transactions supported by the MAC solution. Illegal access results in an error indication. For more information about the standard, see AMBA AXI4-Stream Protocol Specification (ARM IHI 0051A) (Arm
