8.2 ASF Sensor Environmental Event
The document in ASF specification version 0.73 has indicated the listed table is presented as a guide
only (Section 3.3.5.1 Page 8). It is not intended to represent a complete list of the possible
environmental events from a system. The definition of the Event is shown as follow.
8.2.1 Temperature: Get Event Data message
In the W83791D/G, 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.

Sensor device
Sensor number
The W83791D/G is complying ASF 1.0 specification and the value is 0x68.
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 W83791D/G is APR assigned address.
Temperature 1: 0Eh (Don’t use 00h and FFh. Therefore 01h Æ VIN0).
Temperature 2: 0Fh
Temperature 3: 10h
