After the judge shall have received the objections to his main charge, together with any special charges offered, he may make such changes in his main charge as he may deem proper, and the defendant or his counsel shall have the opportunity to present their objections thereto and in the same manner as is provided in Article 36.15, and thereupon the judge shall read his charge to the jury as finally written, together with any special charges given, and no further exception or objection shall be required of the defendant in order to preserve any objections or exceptions theretofore made. After the argument begins no further charge shall be given to the jury unless required by the improper argument of counsel or the request of the jury, or unless the judge shall, in his discretion, permit the introduction of other testimony, and in the event of such further charge, the defendant or his counsel shall have the right to present objections in the same manner as is prescribed in Article 36.15. The failure of the court to give the defendant or his counsel a reasonable time to examine the charge and specify the ground of objection shall be subject to review either in the trial court or in the appellate court.
