3.1.2 System control and configuration
The purpose of the system control and configuration registers is to provide overall management
of:
• TrustZone behavior
• memory functionality
• interrupt behavior
• exception handling
• program flow prediction
• coprocessor access rights for CP0-CP13.
The system control and configuration registers also provide the processor ID.
The system control and configuration registers consist of three 32-bit read only registers and
eight 32-bit read/write registers. Figure 3-1 shows the arrangement of registers in this functional
group.
Figure 3-1 System control and configuration registers
To use the system control and configuration registers you read or write individual registers that
make up the group, see Use of the system control coprocessor on page 3-12.
