Table 142. INT1_DURATION_G description
WAIT enable. Default value: 0 (0: disable; 1: enable)
Duration value. Default value: 000 0000
D6 - D0 bits set the minimum duration of the interrupt event to be recognized. Duration
steps and maximum values depend on the ODR chosen.
WAIT bit has the following meaning:
Wait = ’0’: the interrupt falls immediately if signal crosses the selected threshold
Wait = ’1’: if the signal crosses the selected threshold, the interrupt falls only after the
duration has counted the number of samples at the selected data rate, written into the
duration counter register.
Figure 22. Wait disabled
• Wait bit = ‘0’ Interrupt disabled as soon as condition
is no longer valid (ex: Rate value below threshold)
