External Bus Interface (EBI)
29.1
Introduction
The EBI manages the transfer of information between the internal buses and the memories or peripherals
in the external address space. The EBI includes a memory controller that generates interface signals to
support a variety of external memories. This includes single data rate (SDR) burst mode flash, SRAM, and
asynchronous memories. It supports up to four regions (via chip selects), each with its own programmed
attributes.
