11.7 TAPP: TAP PULSE REGISTER
This value sets the number of samples for which a tap pulse must exceed the TAP_TH
threshold before it is rejected as not a tap event. If the values detected by the sensor exceed
the TAP_TH threshold for longer than the reject count, no tap event is detected and the
interrupt is not set. See also Section 9.6 Tap Detection.
