3.2 INTERRUPT SETTINGS

becomes valid, the interrupt pin is triggered to a high level. All interrupt criteria are combined

Interrupt criteria are using digital code coming from digital filter output. As a consequence all

thus it does not depend on selected bandwidth. Timings used for any motion interrupt and alert
