When it is touched or has settled.
Or when an offensive player interferes with a defensive player attempting to field a batted ball while over foul territory.

Here is the complete ASA 2014 Text:
FOUL BALL: A batted ball that:
A. Settles or is touched (not caught) on or over foul territory between home and first base or between home and third base.
B. Bounds or rolls past first or third base on or over foul territory.
C. While over foul territory, touches the person, attached or detached equipment or clothing of a player or an umpire, orany object foreign to the natural ground.
D. While over foul territory, an offensive player interferes with a defensive player attempting to field a batted ball.
E. First hits the ground over foul territory beyond first or third base.
F. Touches the batter or the bat in the batter's hand(s) a second time while the batter is within the batter's box

NHFS has one additional text, but that is not the crux of this issue.

They both define a foul ball the same, which is the way I read the OP.

There is no such thing as an attempt to play the Ball.
