Tennessee Code Title 40. Criminal Procedure § 40-11-141

(a) A defendant released before trial shall continue on release during trial or release pending trial under the same terms and conditions as were previously imposed, unless the court determines pursuant to § 40-11-137 or § 40-11-144 that other terms and conditions or termination of release are necessary to assure the defendant's presence during trial, or to assure that the defendant's conduct will not obstruct the orderly and expeditious progress of the trial.

(b) If after the defendant is released upon personal recognizance, an unsecured personal appearance bond, or any other bond approved by the court, the defendant violates a condition of release, is charged with an offense committed during the defendant's release, or engages in conduct which results in the obstruction of the orderly and expeditious progress of the trial or other proceedings, then the court may revoke and terminate the defendant's bond and order the defendant held without bail pending trial or without release during trial.
