Privileged instructions
The output signal nTRANS allows the implementation of coprocessors, or coprocessor
instructions, that can only be accessed from privileged modes. The signal meanings are
given in Table 4-4.
If used, the nTRANS signal must be sampled at the same time as the coprocessor
instruction is fetched and is used in the coprocessor pipeline Decode stage.
If a User mode process, with nTRANS LOW, tries to access a coprocessor instruction
that can only be executed in a privileged mode, the coprocessor responds with CPA and
CPB HIGH. This causes the ARM7TDMI processor to take the undefined instruction
trap.
