A threshold monitor uses a programmed low threshold value and a programmed high threshold value to track the data source in the queue and cause an interrupt or status when a threshold is broken, either below the low value or above the high value. This is useful for software to replenish empty buffers when a queue has too few, or for a queue to accumulate enough elements so that software must start processing them, or for debug. The threshold being broken will cause the up or down event.
