9. System Controller
6042DS–ATARM–14-Dec-06
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 4K bytes of address space,
between addresses 0xFFFF F000 and 0xFFFF FFFF. Each peripheral has an address space of
up to 512 Bytes, representing up to 128 registers.

erals. Note that the Memory Controller configuration user interface is also mapped within this
address space.
