4.2.30 Build Options Registers

Build options registers reflect the build configuration options used to build the processor. They

do not reflect any pin-configuration options. These registers are:

• read-only registers

• accessible in Privileged mode only.

Note

These registers are implemented from the r1pm releases of the processor. Attempting to access

these registers in r0pm releases of the processor results in an Undefined Instruction exception.

Table4-54 shows how the bit values correspond wi th the Build Options 1 Register.

To access the Build Options 1 Register, write CP15 with:

MRC p15, 0, <Rd>, c15, c2, 0 ; read Build Options 1 Register
