The duration of the automatic level-calibration routine has an impact on accuracy. The impact is highly dependent on the start-time characteristic of the actuator. The auto-calibration routine expects the actuator to have reached a steady acceleration before the calibration factors are calculated. Because the start-time characteristic can be different for each actuator, the AUTO_CAL_TIME[1:0] bit can change the duration of the automatic level-calibration routine to optimize calibration performance.
