The minimum reset threshold of the supervisory circuit, after taking into account of the maximum absolute error, should be higher than the minimum operating voltage of the microprocessor and the other circuitry. For example, if the microprocessor requires a minimum of 2.7V to operate, the minimum reset threshold must be higher than 2.7V. In this scenario, a supervisory circuit with a typical reset threshold of 3.059V, and tolerance of 2.5% would satisfy the requirement. This is because the minimum possible threshold, 2.983V, is still higher than 2.7V.
