INT1_DURATION_G (38h)

Angular rate sensor interrupt duration register (r/w).

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.
