9. System Controller
The System Controller manages all vital blocks of the microcontroller: interrupts, clocks, power,
time, debug and reset.
The System Peripherals are all mapped within the highest 6 Kbytes of address space, between
addresses 0xFFFF EA00 and 0xFFFF FFFF. Each peripheral has an address space of 256 or
512 Bytes, representing 64 or 128 registers.
Figure 9-1 on page 20 shows the System Controller block diagram.
Figure 8-1 on page 15 shows the mapping of the User Interfaces of the System Controller
peripherals.
