When the processor attempts to execute an instruction that neither it nor a coprocessor
can perform (including all undefined instructions) this causes the processor to take the
undefined instruction trap.

C represents the current mode-dependent value
T represents the current state-dependent value.
Coprocessor instructions are not available in Thumb state.
CPA and CPB are HIGH during the undefined instruction trap.
