5.2.7 Output Queue Threshold Register
The Output Queue Threshold register is composed of four 4-bit fields. Each field specifies the threshold value
of a given priority for all output queues. These values have a range of 0 to 240, with a granularity of 16.
When the number of packets in a queue
the threshold value of a given priority, the corresponding output
queue grant is low (‘0'b).
