memory map summary

Table 2 shows the memory map address ranges of the device. Internal memory is always located at address
0 and can be used as both program and data memory. The configuration registers for the common peripherals
are located at the same hex address ranges. The external memory address ranges in the device begin at the
address location 0x8000 0000.

† The number of EMIF address pins (EA[21:2]) limits the maximum addressable memory (SDRAM) to 128MB per CE space. To get 256MB of
addressable memory, additional general-purpose output pin or external logic is required.
