10. ASF SENSOR ENVIRONMENTAL EVENT
10.1 Temperature: Get Event Data message
In the W83792D, it has three temperatures for monitoring System Board, CPU1, and CPU2. The listed
table show that have the entity ID, entity instance, event source type, event type, event offset, and so
on.

Threshold-based: 0x01h.
The ASF specification indicates that the Sensor Device is the SMBus address of the
sensor that caused the event for the PET Frame. Therefore, the Sensor Device of
the W83792D is ARP assigned address.
Temperature 2: 0Eh
Temperature 3: 0Fh
Temperature 1: 07h (System board)
Temperature 2/3: 03h (Processor)
These are defined in Table 6 of PET v1.0 specification. This value is programmable
because that may be used in add-in-card or connected to other device.
