11.7
11.7.1
Access: Read-only
The CP Register 0 contains specific hardware information. The contents of the read accesses are determined by the
opcode_2 field value. Writing to Register 0 is unpredictable.
11.7.1.1
The ID code register is accessed by reading the register 0 with the opcode_2 field set to 0.
The contents of the ID code is shown below:
• LayoutRev[3:0]: Revision
Contains the processor revision number
