The CNTCV characteristics are:
Indicates the current count value.
The power domain of CNTCV is IMPLEMENTATION DEFINED.
For more information, see 'Power and reset domains for the system level implementation of the Generic Timer'.
CNTCV is a 64-bit register.

Frame | Accessibility |
---|---|
CNTControlBase | RW |
CNTReadBase | RO |
A write to CNTCV must be visible in the CNTPCT register of each running processor in a finite time.
For the instance of the register in the CNTControlBase frame:
In an implementation that supports 64-bit atomic memory accesses, this register must be accessible using a 64-bit atomic access.
Component | Frame | Offset | Instance | Range |
---|---|---|---|---|
Timer | CNTControlBase | 0x008 | CNTCV | 63:0 |
Accesses to this interface are RW.
Component | Frame | Offset | Instance | Range |
---|---|---|---|---|
Timer | CNTReadBase | 0x000 | CNTCV | 63:0 |
Accesses to this interface are RO.
