1. Cumulative reference accuracy is the combined accuracy of the reference voltage and the input offset voltage of the hysteretic
comparator. Cumulative accuracy equals to the average of the low-level and high-level thresholds of the hysteretic comparator.
2. Ensured by design, not production tested.
