(1) The listed minimum pulse width does not take into account the limitation that all relevant HCCAP registers must be read and RISE/FALL event flags cleared within the pulse width to ensure valid capture data.
(2) HRCAP step size will increase with low voltage and high temperature and decrease with high voltage and low temperature. Applications that use the HRCAP in high-resolution mode should use the HRCAP calibration functions to dynamically calibrate for varying operating conditions.
