What is the proper procedure to stay execution of a sentence for multiple convictions for the same criminal offence?

Section 654, subdivision (a) provides in pertinent part: "An act or omission that is punishable in different ways by different provisions of law shall be punished under the provision that provides for the longest potential term of imprisonment, but in no case shall the act or omission be punished under more than one provision." The statute does not prohibit multiple convictions for the same conduct, only multiple punishments. (People v. Monarrez (1998) 66 Cal.App.4th 710, 713.) "In such a case, the proper procedure is to stay execution of sentence on one of the offenses." (Ibid.)
