The FCU topping stop limits fuel flow which in turn limits the TOT. So no TOT trigger. The stop setting also requires adjustment after certain maintenance tasks to ensure engine produces max design power. Below is a screenshot of the
EASA TCDS which shows the TOT limits with the engine side remaining the same regardless of the SB 113 status.
