Method for operating a processor unit uses an interrupt drive to update a time cell via an updating priority routine while checking the time cell via a reaction priority routine on attaining a reaction criterion.

摘要

A processor (2) uses an interrupt drive to update a time cell (8) by applying an updating priority routine and checks the time cell by applying a reaction priority routine on attaining a reaction criterion. It then executes a reaction if necessary. The updating priority routine is higher than the reaction priority routine.
