I am not aware of a specific ASA mechanic for this; it is a new application for a new rule, where previously none existed. I use the NCAA mechanic, or a version of it.

I personally do not ever grant "take charge" or "I'm tired of waiting" time outs. The rule is the pitcher has 20 seconds; period. The batter doesn't get to choose pitch on demand at her timing. So, if a batter requests time, I first say "no", if requested again, I say "play". If the batter steps back and pitcher also steps back, I direct both to continue play by saying "Time was not granted. Play ball." If the pitcher violates the 20 second count, I step out, declare "Dead ball. The pitcher has violated the 'time between pitches' rules'; that is Ball 'x' on the batter. The count is now ....." Step back in, and say "Play".

This should be correct because time is out whenever the plate umpire is attending "other duties"; like making a ruling and award. So dead ball for that reason.
