Is assault with a deadly weapon a lesser included crime?

Appellant claims that the trial court erred in failing to instruct the jury sua sponte on the crime of assault with a deadly weapon. Whether or not assault with a deadly weapon is a lesser included offense when a defendant is charged both with robbery and a "use" allegation, a trial court, as we explained in People v. Flannel (1979) 25 Cal.3d 668, 683-686, 160 Cal.Rptr. 84, 603 P.2d 1, is required to give such an instruction only if there is substantial evidence to support a jury's determination that the defendant was in fact only guilty of the lesser offense.
