Tri-Mode Ethernet MAC Address Space
When the core is generated in
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
the Ethernet MAC is incorporated into the address space of the Ethernet AVB Endpoint
core as illustrated in
