The timestamp clock synchronization is run and the events are logged by the BIOS POST every time the system boots. In addition
during the shutdown from some Operating Systems the BIOS SMI Handler is called to run timestamp clock synchronization and log
the events.
Table 70: System Event Sensor Typical Characteristics
0001h = BIOS POST
0033h = BIOS SMI Handler
Event Direction and
Event Type
[7] Event direction
0b = Assertion Event
1b = Deassertion Event
[6:0] Event Type = 6Fh (Sensor Specific)
[7:6] – 00b = Unspecified Event Data 2
[5:4] – 00b = Unspecified Event Data 3
[3:0] – Event Trigger Offset
01h = System Boot
05h = Timestamp Clock Synchronization
For Event Trigger Offset 05h only (Timestamp Clock
Synchronization)
00h = 1st in pair
80h = 2nd in pair
