sets if the operation generates a carry;
sets if overflow is generated;
sets if the result is zero;
When the input conditions are true, take the opposite sign of
the Source (N7:3) and store the result in the Destination
(N7:12). This instruction turns positive values into negative
values and negative values into positive values.
