9. System Controller
The System Controller manages all vital blocks of the microcontroller: interrupts, clocks, power,
time, debug and reset.
The System Controller peripherals are all mapped to the highest 4 Kbytes of address space,
between addresses 0xFFFF F000 and 0xFFFF FFFF.
Figure 9-1 on page 27
and
Figure 9-2 on page 28
show the product specific System Controller
Block Diagrams.
Figure 8-1 on page 20
shows the mapping of the of the User Interface of the System Controller
peripherals. Note that the memory controller configuration user interface is also mapped within
this address space.
