The Opcode_1 field Should Be Zero except when the values specified are used to
select the desired operations. Using other values results in Unpredictable
behavior.
The Opcode_2 and CRm fields Should Be Zero except when the values specified
are used to select the desired behavior. Using other values results in Unpredictable
behavior.

Description
For reads: The data returned when reading from
this location is unpredictable. It can have any
value.
For writes: Writing to this location causes
unpredictable behavior, or an unpredictable
change in device configuration.
An instruction that accesses CP15 in the manner
indicated takes the Undefined instruction
exception.
When writing to this location, all bits of this field
Should Be Zero.
