52h = Power Supply 1 AC Power Input
53h = Power Supply 2 AC Power Input
Event Direction and
Event Type
[7] Event direction
0b = Assertion Event
1b = Deassertion Event
[6:0] Event Type = 01h(Threshold)
[7:6] – 01b = Trigger reading in Event Data 2
[5:4] – 01b = Trigger threshold in Event Data 3
[3:0] – Event Trigger Offset as described in Table 22
Reading that triggered event
Threshold value that triggered event
