5.2.18 Output Queue Status Registers 0-3
These four registers provide the output queue empty status, as well as the priority full status. Each register
provides the status bits for four output queues, as indicated in the OCM address listing below.
If an output queue is empty while some of its priorities are declared full (this is the case of a threshold being
programmed at 0), the status register reports that the queue is indeed empty. The full information is only
available if the queue is non-empty.
