ICM-42607x and ICM-42670x APEX Motion Functions: Description and Usage
■APEX (Advanced Pedometer and Event Detection – NeXt Generation) Motion is a digital block inside the ICM- 42607x AND ICM-42670x accelerometer family of Inertial Measurement Units. APEX processes accelerometer data, extracts measurements, and asserts motion-specific interrupts. APEX features use accelerometer data, not gyroscope data.
■Each APEX feature has its own set of configuration bits, and the features can run concurrently. Most APEX features assert an interrupt after a motion event (Significant Motion Detection for example asserts an interrupt but does not provide any measurements), while other features will extract data and provide it to the user (Pedometer counts steps and can also assert interrupts).
■The APEX features in ICM-42607x and ICM-42670x accelerometer consists of the following features:
▲Tilt: triggers an interrupt when the Tilt angle exceeds 35 degrees for more than a programmable time.
▲Low-G: triggers an interrupt when absolute value of accelerometer combined axis falls below a programmable threshold and stays below the threshold for a programmable time.
▲Freefall: triggers an interrupt when device freefall is detected and outputs freefall duration.
▲Pedometer: tracks Step count and triggers a Step Detect Interrupt.
▲Wake on Motion: detects a motion through accel samples exceeding a programmable threshold with respect to a reference value. This motion event can be used to enable chip operation from sleep mode.
▲Significant Motion Detector: Detects significant motion based on accelerometer data.
