Status Type Status Description
0000b
0Bh to
10h
9
Deasserted (no
send)
The event is in the deasserted state, but the ASF-sensor does
not want a PET to be sent on this condition. This will typically be
used when a device sets its initial status upon initialization. The
alert-sending device uses this state information to update its
state tracking information, but does not generate a PET on a
change.
0001b
0Bh to
10h
9
Asserted (no
send)
The event is in the asserted state, but the ASF-sensor does not
want a PET to be sent on this condition. This will typically be
used when a device sets its initial status upon initialization. The
alert-sending device uses this state information to update its
state tracking information, but does not generate a PET on a
change.
0010b
0Bh to
10h
Deasserted
(send)
A deassertion event should be sent when the alert-sending
device either first accesses this device, or detects a change to
this state during operation.
0011b
0Bh to
10h
Asserted
(send)
An assertion event should be sent when the alert-sending
device either first accesses this device, or detects a change to
this state during operation.
0100b
02h (or
0Bh to
10h
10
)
Disabled
The device is present within the ASF-sensor, but its associated
event has been disabled via hardware or software methods.
0101b
02h (or
0Bh to
10h
10
)
Undetermined
The sensor device has not yet assessed the present event
state, possibly because the device is initializing.
0110b — Reserved Reserved for future definition by this specification.
0111b 02h
Event Status
End
The ASF-sensor has no device associated with either the value
specified in Event Status Index or any higher value.

— Reserved Reserved for future definition by this specification.
9
The ASF-sensor transmits the PET fields for these Status Value codes to enable
implementations to optionally support start-up state logging.
10
Any data that an ASF-sensor might return with this Status Type is undefined and should not be
interpreted by the message initiator. This function is provided to allow possible simplification of
an ASF-sensor device’s state-machine implementation.
