1. A method to determine a power-up parameter for a circuit board including an electronic processor, the method comprising:

  • electrically exciting a second-order circuit to generate an underdamped transient response;

    receiving, at a comparator coupled to the second-order circuit, the underdamped transient response;

    generating, in response to the underdamped transient response received at the comparator, a plurality of edges;

    receiving, at a single general purpose input/output pin of the electronic processor, the plurality of edges;

    determining a discharge time based on the plurality of edges;

    determining a damping frequency based on the plurality of edges;

    determining the power-up parameter based on the discharge time and the damping frequency; and

    controlling the circuit board based on the power-up parameter.
