Chapter 10: Configuration and Status
Tri-Mode Ethernet MAC Address Space
When the core is generated in “EDK pcore Format” for import into EDK and connection to
the xps_ll_temac, the address space defined in this section is not included and the address
space will return 0s for a read and all writes will be ignored.
When the core is generated in “Standard CORE Generator Format” , the address space of
the Ethernet MAC is incorporated into the address space of the Ethernet AVB Endpoint
core as illustrated in
Figure 10-3 . The Ethernet MAC Address space is then split into two
sections:
• “MAC Configuration and Statistics”
• “MAC MDIO Registers”
MAC Configuration and Statistics
Table 10-17 defines the statistic registers and configuration registers of the Tri-Mode
Ethernet MAC core. These are listed with their assigned addresses. See the Tri-Mode
Ethernet MAC User Guide (
UG138 ) and the Ethernet Statistics User Guide ( UG170 ) for
additional descriptions of these registers.
MAC Address Filter Registers
The Address Filter, optionally present in the Tri-Mode Ethernet MAC LogiCORE™ IP
solution, must not used. Instead, new
“Legacy MAC Header Filters” have been added to
the Receiver Legacy Traffic path, which is capable of providing address recognition for
eight unique MAC addresses. See
“MAC Header Filter Configuration.”

A maximum of 64 configurable Ethernet MAC statistics registers can
be accessed through the PLB interface (let the statistics registers be
numbered by STATISTIC_NUMBER, from 0 to 63). Each statistic
returns a 64-bit counter value. Accordingly:
Address of STATISTIC_NUMBER =
(PLB_base_address + 0x4000 + [STATISTIC_NUMBER * 8])
