I want to use MMA8451/2/3 to start / wake up a wireless module. It requires certain pin on the module to be pulled low for 1 second or more. From the datasheet I know that MMA8451/2/3 has active high interrupts but I could not find the duration for which the interrupt pin remains high. Is this duration defined in the datasheet? Is it user configurable?
Also, it would help reduce a few components if the interrupt pins can be can be configured to be active low. i.e. pin is normally high but goes low when motion is detected.
