Standards for Smart Sensing 283• Sensor;• Buffered sensor;• Data sequence sensor;• Buffered data sequence sensor;• Actuator;• Event sequence sensor.Figure 12.10 illustrates the response of a STIM to a trigger [6]. The triggeringfunction provides a means for an NCAP to send the STIM a commandfor an action to take place (the trigger signal) and for the STIM to indicate thetime when the action occurred (trigger acknowledgment). That general flow iselaborated in the standard to show the sensor and actuator activity that occursconcurrently in the quiescent and triggered states. Other possible triggeringoptions include:Power oninitializationInitialization completeData transport completeTrigger assertedQuiescentDatatransportAbortactionTriggernegatedTriggeredData transport activeAction completeAcknowledgetriggerTriggernegatedRemoveacknowledgeFigure 12.10 General response of a STIM to a trigger [6].
