System Controller
The System Controller is a set of peripherals, which allow handling of key elements of the sys-
tem, such as power, resets, clocks, time, interrupts, watchdog, etc.
The System Controller User Interface embeds also the registers allowing to configure the Matrix
and a set of registers for the chip configuration. The chip configuration registers allows
configuring:
– 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 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.
