The Complement Register (COMR) instruction creates a ones complement of the value in the specified register, stores the result in the same register, and sets or clears the [[Sign Flag]] and [[Zero Flag]] according to the results. Note that a ones complement of any 16-bit value is equivalent to the value xor'ed with $FFFF (value^$FFFF).<br/>
