System Static Configuration Read Register, DCS_CFG_R
The DCS_CFG_R register discovers the values that were applied to system static configuration input pins when the system was powered on, that is, system power-on reset.
The following table shows the bit assignments.
Table 3-35 DCS_CFG_R Register bit assignments
|[31:28]||NUM_CPU3||RO||Reserved for the NUM_CPU configuration for cluster 3. This system does not contain a cluster 3 and this field is RAZ.|
|[27:24]||NUM_CPU2||RO||Reserved for the NUM_CPU configuration for cluster 2. This system does not contain a cluster 2 and this field is RAZ.|
Returns the NUM_CPU configuration for Cluster 1, Cortex®‑A7 cluster:
Returns the NUM_CPU configuration for Cluster 0, Cortex‑A15 cluster:
|[1:0]||CFG_ACTIVECLUSTER||RO||Returns the value that was driven on the CFG_ACTIVECLUSTER configuration inputs at the last system power-on reset.|
