2.4 Memory Map Summary
Table 2-3 shows the memory map address ranges of the device. Table 2-4 depicts the expanded map of
the Configuration Space (0x0180 0000 through 0x0FFF FFFF). The device has multiple on-chip memories
associated with its two processors and various subsystems. To help simplify software development a
unified memory map is used where possible to maintain a consistent view of device resources across all
bus masters.
