Threshold

Threshold registers INT1_THS_xH and INT_THS_xL (respectively MSB and LSB) define

the reference angular rates used by the interrupt generation circuitry.

The value of 1 LSB of the threshold depends on the selected full scale (Table 23).

5.4

Duration

The content of the Dx bits of the duration register sets the minimum duration of the interrupt

event to be recognized.

The duration steps and maximum values depend on the ODR chosen.

The duration time is measured in N/ODR, where N is the content of the duration register and

the ODR is 100, 200, 400, 800.
