8.1.12.2.52 CM_L4_WKUP_AON_CLKSTCTRL Register (offset = CCh) [reset = 6h]
CM_L4_WKUP_AON_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.

Controls the clock state transition of the always on L4 clock domain.
0x0 = NO_SLEEP : Sleep transition cannot be initiated. Wakeup
transition may however occur.
0x1 = SW_SLEEP : Start a software forced sleep transition on the
domain.
0x2 = SW_WKUP : Start a software forced wake-up transition on the
domain.
