System control coprocessor registers

This section describes all of the registers in the system control coprocessor. The section presents
a summary of the registers and descriptions in register order of CRn, Opcode_1, CRm,
Opcode_2.

For more information on using the system control coprocessor and the general method of how
to access CP15 registers, see the ARM Architecture Reference Manual.

4.2.1

Register allocation

Table 4-2 shows a summary of address allocation and reset values for the registers in the system
control coprocessor where:
•

CRn is the register number within CP15

•

Op1 is the Opcode_1 value for the register

•

CRm is the operational register

•

Op2 is the Opcode_2 value for the register.
