Revision: 1.0
Release Date: 01/17/2014
6 Programmable Interrupts
The MPU-9250 has a programmable interrupt system which can generate an interrupt signal on the INT pin.
Status flags indicate the source of an interrupt. Interrupt sources may be enabled and disabled individually.

For information regarding the interrupt enable/disable registers and flag registers, please refer to the MPU-
9250 Register Map and Register Descriptions document. Some interrupt sources are explained below.
6.1 Wake-on-Motion Interrupt
The MPU-9250 provides motion detection capability. A qualifying motion sample is one where the high
passed sample from any axis has an absolute value exceeding a user-programmable threshold. The
following flowchart explains how to configure the Wake-on-Motion Interrupt. For further details on individual
registers, please refer to the MPU-9250 Registers Map and Registers Description document.
In order to properly enable motion interrupts, the INT pin should be connected to a GPIO on the system
processor that is capable of waking up the system processor.
