cop/break?

Hi,
I have this assignment that requires me to describe the cop and break instruction on "many of the current processors." I've looked and looked and cant find them.

Anybody have a clue?
Thanks,
Cboy

    Never heard of 'cop'. Maybe it should be 'nop', an instruction that does nothing. Sometimes used for tight timing loops.

    'break' might be a trap instruction, such as the 80x86 software ints.

    AFAIK, 'cop' and 'break' are *not* on "many of the current processors".
