Hi,  I wonder if anyone can help with a sleep / interrupt problem?  When the sensor is awake and with the registers set for our application the device generates interrupts as expected.  If we change just the sleep register to put it in a low power mode the device never generates an interrupt again.  Is there a secret undocumented sleep sequence that we have to follow?

Thanks.
