External Memory Areas
Internal Memory Mapping
Figure 16-2
Figure 16-2. External Memory Areas
Within the Internal Memory address space, the Address Decoder of the Memory Controller
decodes eight more address bits to allocate 1-Mbyte address spaces for the embedded
memories.
The allocated memories are accessed all along the 1-Mbyte address space and so are repeated
n times within this address space, n equaling 1M byte divided by the size of the memory.
When the address of the access is undefined within the internal memory area, i.e. over the
address 0x0040 0000, the Address Decoder returns an Abort to the master.
shows the assignment of the 256-Mbyte memory areas.
