Table 139. 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

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_ time. If QUIET[1:0] bits are set to a different value, 1LSB corresponds to

4*ODR_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_ time. If SHOCK[1:0] bits are set to a different value, 1LSB corresponds

to 8*ODR_time.
