9. 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 the 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 stan-
dard ARM instruction set, as the Load/Store instruction have an indexing mode of ±4 Kbytes.
Figure 9-1 on page 29
shows the System Controller block diagram.
Figure 8-1 on page 20
shows the mapping of the User Interfaces of the System Controller
peripherals.
