Event Data 1
[7:6] – 00b = Unspecified Event Data 2
01b = Trigger reading in Event Data 2
10b = OEM code in Event Data 2
11b = Sensor-specific event extension code in Event Data 2
[5:4] – 00b = Unspecified Event Data 3
01b = Trigger threshold value in Event Data 3
10b = OEM code in Event Data 3
11b = Sensor-specific event extension code in Event Data 3
[3:0] – Offset from Event/Reading Code for threshold event.
Event Data 2 – Reading that triggered event, FFh or not present if unspecified.
Event Data 3 – Threshold value that triggered event, FFh or not present if unspecified. If present, Event
Data 2 must be present.
