10.1 System Controller Mapping
The System Controller peripherals are all mapped to the highest 4 Kbytes of address space,
between addresses 0xFFFF F000 and 0xFFFF FFFF.
Figure 10-2 shows the mapping of the System Controller. Note that the Memory Controller con-
figuration user interface is also mapped within this address space.
