Dead-Ball Foul Sequence/Mechanics

[PocketSidewalk]

What's the correct sequence for signaling a dead-ball foul? (Specifically, I'm thinking about presnap fouls as opposed to late hits or fouls after the play.)

i.e., do you throw the flag first, then whistle, then signal to stop the clock?

Just trying to get a feel for which is the most important, then what comes second, etc.

I'm sure after a little time this will all happen pretty quickly (and hopefully become second nature), but as a new official I want to be sure of my priorities.
