The defendant may show cause against pronouncement of judgment:
1. That the defendant is insane;
2. That the defendant has good cause to offer, either in arrest of judgment or for a new trial, in which case the court may order the judgment to be deferred, and may proceed to decide upon the motion in arrest of judgment or for a new trial;
3. That the defendant is not the person against whom the verdict was rendered; or 4. That the defendant has been pardoned of the offense for which judgment is to be rendered.
