System Controller
The System Controller is a set of peripherals that allows handling of key elements of the system, such as power, resets,
clocks, time, interrupts, watchdog, etc.
The System Controller User Interface also embeds the registers that configure the Matrix and a set of registers for the
chip configuration. The chip configuration registers configure EBI chip select assignment and voltage range for external
memories
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 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 has an indexing mode of ±4 Kbytes.
Figure 9-1 on page 24 shows the System Controller block diagram.
Figure 8-1 on page 19 shows the mapping of the User Interfaces of the System Controller peripherals.
