WAIT

D6 - D0

Table 65. INT1_DURATION description

WAIT enable. Default value: 0 (0: disable; 1: enable)

Duration value. Default value: 000 0000

The D6 - D0 bits set the minimum duration of the interrupt event to be recognized. Duration

steps and maximum values depend on the ODR chosen.

The WAIT bit has the following meaning:

Wait = â0â: the interrupt falls immediately if the signal crosses the selected threshold.

Wait = â1â: if the signal crosses the selected threshold, the interrupt falls only after the

duration has counted a number of samples at the selected data rate, written into the

duration counter register.
