8.1.12.1.61 CM_PER_CLK_24MHZ_CLKSTCTRL Register (offset = 150h) [reset = 2h]
CM_PER_CLK_24MHZ_CLKSTCTRL is shown in
and described in
This register enables the clock domain 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.
