agent_ccc0_ccc_event_counter_mask

         This register is used to program the event counter. Each bit of this register enables the performance counter to increment if the event occurs. A value of 1 for a bit indicates that this event should be counted.
If multiple bits are set to 1, the logic will only count if all of the corresponding events occur on the same cycle. This allows for combinations of events, such as a directory miss for a Shared line request. The events that can be counted are all related to directory accesses and occur in the same cycle of the pipeline, so they can be combined easily.
When an event satisfies all of the requirements, the ccc_event_counter_value register will be updated.
A value of 1 indicates that the event is selected for counting. A value of 0 the event is not selected. By default, this register will be set to 0 for all bits, indicating no event counting should occur.

Access mode: SECURE | PRIVILEGEMODE

Note: The processor must make a secure, privileged bus access to this register. You can configure processor mode settings in the control registers of the ARM Cortex-A53 MPcore processor. For more information about processor modes, please refer to the ARM Infocenter.

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.
