Potential Unimplemented Instructions
Some Nios II processor cores do not support all instructions in hardware. In this case,
the processor generates an exception after issuing an unimplemented instruction.
Only the following instructions can generate an unimplemented instruction
exception:
■
■
■
■
■
■
■
■
All other instructions are guaranteed not to generate an unimplemented instruction
exception.
An exception routine must exercise caution if it uses these instructions, because they
could generate another exception before the previous exception is properly handled.
