via the EMC, as well as the SRAM located on another AHB, if it is not being used by the
USB block. However, using memory other than the Ethernet SRAM, especially off-chip
memory, will slow Ethernet access to memory and increase the loading of its AHB.
The Ethernet block interfaces between an off-chip Ethernet PHY using the Reduced MII
(RMII) protocol and the on-chip Media Independent Interface Management (MIIM) serial
bus.
