Power Scheduler Control-1 (PWR_SCHED_CTRL2) – Offset 8144
These bit enable by EP type those EPs classes that are considered for determining next periodic active interval for pre-wake of the periodic_active signal.
EP classes that are disabled may never be observed in setting of the periodic_active signal.
