Causes a branch if the N (negative) bit and the V (overflow) bit are
        either both set or both clear. That is, branch if the sign of a valid
        twos complement result is, or would be, positive. When used after a
        subtract or compare operation on twos complement values, this
        instruction will branch if the register was greater than or equal to the
        memory register.
