This object represents the falling threshold value for this
memory resource. A value of zero means that the falling
threshold is not supported for this memory resource.
The value of this object can not be set to higher than or
equal to ceqfpMemoryResRisingThreshold.
A falling (ceqfpMemoryResRisingThreshNotif) notification
will be generated, whenever the memory resource usage
(ceqfpMemoryHCResInUse) is equal to or lesser than this value.
After a falling notification is generated, another
such notification will not be generated until the
ceqfpMemoryResInUse rises above this value and reaches
the ceqfpMemoryResRisingThreshold.
