3.3.16. QoS Range Register

The QoS Range Register characteristics are:


Enables you to program the minimum and maximum values for the ARQOS and AWQOS signals that the latency regulators generate. One register exists for each slave interface.

Usage constraints

Accessible using only secure accesses, unless you set the Secure Access Register. See Table 3.4.


Only has an effect when QOSOVERRIDE is HIGH for the associated interface.


Table 3.19 shows the bit assignments.
