System Controller Mapping
The System Controller’s peripherals are all mapped within the highest 16 KBytes of address
space, between addresses 0xFFFF E800 and 0xFFFF FFFF.
However, all the registers of the System Controller are mapped on the top of the address space.
All the registers of the System Controller can be addressed from a single pointer by using the
standard ARM instruction set, as the Load/Store instruction have an indexing mode of ±4 KB.
Figure 7-1 on page 21
shows the System Controller block diagram.
Figure 6-1 on page 15
shows the mapping of the User Interfaces of the System Controller
peripherals.
