Table 62. INT1_THS_A description

Interrupt 1 threshold. Default value: 000 0000

1 LSb = 16 mg @ FS = 2 g

1 LSb = 32 mg @ FS = 4 g

1 LSb = 62 mg @ FS = 8 g

1 LSb = 186 mg @ FS = 16 g

8.22 INT1_DURATION_A (33h)

D[6:0]

Table 64. INT1_DURATION_A description

Duration value. Default value: 000 0000

1 LSb = 1/ODR

The D[6:0] 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.

Table 66. INT2_CFG_A description

AND/OR combination of interrupt events. Default value: 0

(see Table 67)

6-direction detection function enabled. Default value: 0. Refer to Table 67.

Enable interrupt generation on Z high event. Default value: 0

(0: disable interrupt request;

1: enable interrupt request on measured accel. value higher than preset threshold)
