Table 67. INT_DUR_A register description
Duration of maximum time gap for double-tap recognition. When double-tap
recognition is enabled, this register expresses the maximum time between two
successive detected taps to determine a double-tap event.
1 LSB = 32 TODR.
Expected quiet time after a tap detection: this register represents the time after
the first detected tap in which there must not be any over-threshold event.
1 LSB = 4 TODR.
Maximum duration of over-threshold event: this register represents the maximum
time of an over-threshold signal detection to be recognized as a tap event.
1 LSB = 8 TODR
