1. A method of calibrating a trigger point threshold of data being transferred to first circuitry of an electrical device from second circuitry of the electrical device, comprising:

  • actively adjusting the trigger point threshold, wherein the trigger point threshold determines where bits of the data being transferred from the first circuitry to the second circuitry switch value;

    determining whether noise is present;

    in response to determining the noise is present, ceasing to adjust the trigger point threshold;

    determining whether the noise has ceased; and

    in response to determining that the noise has ceased, actively adjusting the trigger point threshold.
