The following topics describe the coprocessor instructions:
Coprocessor Data oPerations.
Move to Coprocessor from ARM Register or Registers, possibly with coprocessor operations.
Move to ARM Register or Registers from Coprocessor, possibly with coprocessor operations.
MRS (system coprocessor register to ARM register)
Move to ARM register from system coprocessor.
MSR (ARM register to system coprocessor register)
Move to system coprocessor from ARM register.
Execute system coprocessor instruction.
Transfer data between memory and Coprocessor.
Note
A coprocessor instruction causes an Undefined Instruction exception if the specified coprocessor is not present, or if it is not enabled.
This section does not describe VFP or Wireless MMX Technology instructions. XScale-specific instructions are described later in this document.
