7. 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 KB of address space, between

addresses 0xFFFF D000 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 have an indexing mode of ±4 KB.

Figure 7-1 on page 35 shows the System Controller block diagram.
