HeldBall/Shot clock expiry

[LimeyRef]

As a referee who works FIBA rules in Europe, what is the ruling on:

Held ball being called simultaneous with a shot clock expiry? in NCAA and in HS.

Play - A12 has the ball and is guarded by B0, the shot clock is running down and expires simultaneously with the referees whistle for a held ball between A12 and B10.
