8.1.12.1.1 CM_PER_L4LS_CLKSTCTRL Register (offset = 0h) [reset = C0102h]
CM_PER_L4LS_CLKSTCTRL is shown in Figure 8-23 and described in Table 8-30.
This register enables the domain power state transition. It controls the SW supervised clock domain state
transition between ON-PER and ON-INPER states. It also hold one status bit per clock input of the
domain.
