agent_ccc0_ccc_agent_disable_status
This status register is used to indicate that a change to the active agent vector has taken effect. When an agent is removed from the active agent vector, snoops targeting that master may still be queued or inflight. While snoops are outstanding, the master must continue to operate to satisfy snoop requests.
This register indicates that all snoops to the disabled agents have completed and no new snoops will be issued to those agents. The status indicates whether any snoops outstanding at the time of the last modification of the ccc_active_vector register(s) have all completed or not. A value of 1 indicates that the snoops have all completed and it is safe to power off or otherwise disable the masters that were removed from the active vector. A value of 0 indicates that snoops are still outstanding and the master must continue to operate and accept snoops.
