The Jazelle Identity Register allows software to determine the implementation of the Jazelle Extension provided by the processor.

The Jazelle Identity Register is:

in CP14 register c0
a 32-bit read-only register, accessible in all processor modes and security states.

Figure 2.4 shows the bit arrangement of the Jazelle Identity Register.
