highest priority.
(e) QoS Function
The QoS function is available in read-accessing only.
The QoS function is the service function for exception handling at Round-Robin
dmc_id_x_cfg_3<qos_min> is set by a register within the DMC on a port by port basis.
A QoS_max timeout causes the transaction to be raised to a higher priority.
You can also set the dmc_id_x_cfg_3<qos_min> to enable for a specific port so that its
