ARM DDI 0165B
No external coprocessor
Undefined instructions
If you are implementing a system that does not include any external coprocessors, you
must tie both CHSD and CHSE to 10 (ABSENT). This indicates that no external
coprocessors are present in the system. If any coprocessor instructions are received,
they cause the processor to take the undefined instruction trap, allowing the coprocessor
instructions to be emulated in software if required.
The coprocessor-specific outputs from the ARM9E-S must be left unconnected:
•
•
The ARM9E-S implements full ARMv5TE architecture undefined instruction
handling. This means that any instruction defined in the ARM Architecture Reference
Manual as
instruction trap. Any coprocessor instruction that is not accepted by a coprocessor also
results in the ARM9E-S taking the undefined instruction trap.
