8.1.12.1.4 CM_PER_L3_CLKSTCTRL Register (offset = Ch) [reset = 12h]
CM_PER_L3_CLKSTCTRL is shown in
and described in
This register enables the domain power state transition. It controls the SW supervised clock domain state
transition between ON-ACTIVE and ON-INACTIVE states. It also hold one status bit per clock input of the
domain.
