Preliminary
13.6: RXQUE Threshold Registers
These registers specify a queue length threshold at which the corresponding status bit is generated. These
registers should be set equal to the number of queue entries that should cause status to be generated. For
example, if the value was set to five, then no interrupt would be generated until five or more events were
queued on the corresponding receive queue. The threshold is level sensitive, so as long as the length is
greater than or equal to the threshold, the corresponding status bit is set. When this register is set to ’0’, no
thresholding is done.
When the direction bit is set for a receive queue, the threshold has the opposite polarity. For example, as long
as there are more events in the queue than specified in the threshold register, no status would be raised.
