The move from coprocessor (
the specified ARM register.
Data is transferred over the data bus interface, in a similar fashion to a load register
operation.
An interrupt can cause the ARM9E-S to abandon a busy-waiting coprocessor
instruction (see Busy-waiting and interrupts on page 6-17).
Coprocessor operations are only available in ARM state.
