Power, Reset, and Clock Management
8.1.12.2.1 CM_WKUP_CLKSTCTRL Register (offset = 0h) [reset = 6h]
CM_WKUP_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.
