Table 181. INT_DUR2 register description
Duration of maximum time gap for double tap recognition. Default: 0000
When double tap recognition is enabled, this register expresses the maximum time
between two consecutive detected taps to determine a double tap event. The
default value of these bits is 0000b which corresponds to 16*ODR_XL time. If the
DUR[3:0] bits are set to a different value, 1LSB corresponds to 32*ODR_XL time.
Expected quiet time after a tap detection. Default value: 00
Quiet time is the time after the first detected tap in which there must not be any
overthreshold event. The default value of these bits is 00b which corresponds to
2*ODR_XL time. If the QUIET[1:0] bits are set to a different value, 1LSB
corresponds to 4*ODR_XL time.
Maximum duration of overthreshold event. Default value: 00
Maximum duration is the maximum time of an overthreshold signal detection to be
recognized as a tap event. The default value of these bits is 00b which corresponds
to 4*ODR_XL time. If the SHOCK[1:0] bits are set to a different value, 1LSB
corresponds to 8*ODR_XL time.
