OPT2 is used to set the calibration time-out function. If OPT2 is connected to ground, keys will time out and recalibrate after 10 seconds of continuous detection on a key. If OPT2 is left open or connected to Vdd, keys will recalibrate after 60 seconds. In either case the keys will continue to be functional after the time-out, to increased amounts of finger touch.
