A coprocessor data operation is a request from the core for the coprocessor to initiate
some action. The action does not have to be completed for some time, but the
coprocessor must commit to doing it before driving CPB LOW.
If the coprocessor is not capable of performing the requested task, it must leave CPA
and CPB HIGH. If it can do the task, but cannot commit right now, it must drive CPA
LOW but leave CPB HIGH until it can commit. The core busy-waits until CPB goes
LOW.
The cycle timings are listed in Table 6-16 where:
•
Coprocessor data operations are not available in Thumb state.
