Home > Programmers Model > Register descriptions > Write Channel QoS Value Override Register |
The Write Channel QoS Value Override Register characteristics are:
Contains override values for AWQOS, with a register for each slave interface. This value is used if you set the QOSOVERRIDE[4:0] input signal bit for this slave interface and the QoS value regulator is not enabled.
You can also read the current value of the QoS value regulator for write accesses when the regulator is enabled.
Accessible using only Secure accesses, unless you set the Secure Access Register. See Table 3.4.
Available in all CCI-400 configurations.
See Table 3.1.
Figure 3.10 shows the bit assignments.
Table 3.13 shows the bit assignments.

Bits | Reset | Access | Function |
---|---|---|---|
[31:12] | - | RAZ/WI | Reserved. |
[11:8] |
| R/WI | Reads what value is currently applied to transactions with AWQOS=0, provided QOSOVERRIDE is HIGH and the QoS value regulator is enabled. |
[7:4] | - | RAZ/WI | Reserved. |
[3:0] |
| RW | AWQOS value override for the slave interface. |
