The CNTID characteristics are:
Indicates whether counter scaling is implemented.
It is IMPLEMENTATION DEFINED whether CNTID is implemented in the Core power domain or in the Debug power domain.
This register is present only when FEAT_CNTSC is implemented. Otherwise, direct accesses to CNTID are RES0.
CNTID is a 32-bit register.

Indicates whether Counter Scaling is implemented
CNTSC | Meaning |
---|---|
0b0000 |
Counter scaling is not implemented. |
0b0001 |
Counter scaling is implemented. |
All other values are reserved.
In a system that supports Secure and Non-secure memory maps, the CNTControlBase frame, that includes this register, is implemented only in the Secure memory map.
Component | Frame | Offset | Instance |
