LIS2DH Registers Description
Doc ID 022516 Rev 1 41/49
7.22 INT1_DURATION (33h)
D6 - D0 bits set the minimum duration of the Interrupt 2 event to be recognized. Duration
steps and maximum values depend on the ODR chosen.
Duration time is measured in N/ODR, where N is the content of the duration register.
7.23 INT2_CFG (34h)
Table 56. INT1_DURATION register
0 D6D5D4D3D2D1D0
Table 57. INT1_DURATION description
D6 - D0
