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

The reset behaviour of this field is:
CNTVCT can be implemented in any implemented CNTBaseN frame, and in the corresponding CNTEL0BaseN frame, as a RO register.
'CNTCTLBase status and control fields for the CNTBaseN and CNTEL0BaseN frames' describes the status fields that identify whether a CNTBaseN frame is implemented, and for an implemented frame:
For an implemented CNTBaseN frame:
For an implemented CNTEL0BaseN frame:
If the implementation supports 64-bit atomic accesses, then the CNTVCT register must be accessible as an atomic 64-bit value.
