Accessing CNTCV

FrameAccessibility
CNTControlBaseRW
CNTReadBaseRO

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.

CNTCV can be accessed through the memory-mapped interfaces:

ComponentFrameOffsetInstanceRange
TimerCNTControlBase0x008CNTCV63:0

Accesses on this interface are RW.

ComponentFrameOffsetInstanceRange
TimerCNTReadBase0x000CNTCV63:0

Accesses on this interface are RO.
