–

Possibility to store timestamp

•

Event-detection interrupts (fully configurable)

–

Free-fall

–

Wake-up

–

6D orientation

–

Activity/inactivity recognition

–

Stationary/motion detection

•

Finite state machine

The ASM330LHBG1 can be configured to generate interrupt signals activated by user-defined motion patterns. To

do this, up to 16 embedded finite state machines can be programmed independently for motion detection such as

vehicle status (stationary or moving), antitheft alarm and shock detection.

Definition of finite state machine

A state machine is a mathematical abstraction used to design logic connections. It is a behavioral model

composed of a finite number of states and transitions between states, similar to a flow chart in which one can

inspect the way logic runs when certain conditions are met. The state machine begins with a start state, goes to

different states through transitions dependent on the inputs, and can finally end in a specific state (called stop

state). The current state is determined by the past states of the system. The figure below shows a generic state

machine.
