Class Event Data
threshold Event Data 1
[7:6] - 00b = unspecified byte 2
01b = trigger reading in byte 2
10b = OEM code in byte 2
11b = sensor-specific event extension code in byte 2 [5:4] - 00b =
unspecified byte 3
01b = trigger threshold value in byte 3
10b = OEM code in byte 3
11b = sensor-specific event extension code in byte 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, byte 2 must be present.
discrete Event Data 1
[7:6] - 00b = unspecified byte 2
01b = previous state and/or severity in byte 2
10b = OEM code in byte 2
11b = sensor-specific event extension code in byte 2 [5:4] - 00b =
unspecified byte 3
01b = reserved
10b = OEM code in byte 3
11b = sensor-specific event extension code in byte 3
[3:0] - Offset from Event/Reading Code for discrete event state
Event Data 2
[7:4] - Optional offset from ‘Severity’ Event/Reading Code. (0Fh if
unspecified).
[3:0] - Optional offset from Event/Reading Type
Code for previous discrete
event state. (0Fh if unspecified.)
Event Data 3 Optional OEM code. FFh or not present if unspecified.
