CNTID, Counter Identification Register
The CNTID characteristics are:
Indicates whether counter scaling is implemented.
The power domain of CNTID is IMPLEMENTATION DEFINED.
This register is present only when FEAT_CNTSC is implemented. Otherwise, direct accesses to CNTID are RES0.
CNTID is a 32-bit register.
The CNTID bit assignments are:
CNTSC, bits [3:0]
Indicates whether Counter Scaling is implemented
Counter scaling is not implemented.
Counter scaling is implemented.
All other values are reserved.
Accessing the CNTID
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.
CNTID can be accessed through the memory-mapped interfaces:
Accesses on this interface are RO.
