8.1.12.2.7 CM_L3_AON_CLKSTCTRL Register (offset = 18h) [reset = 1Ah]
CM_L3_AON_CLKSTCTRL is shown in Figure 8-90 and described in Table 8-98.
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.

4 CLKACTIVITY_DEBUG_C R 1h
This field indicates the state of the Debugss CLKA clock in the
LKA
domain.
3 CLKACTIVITY_L3_AON_ R 1h
This field indicates the state of the L3_AON clock in the domain.
GCLK
0x0 = Inact : Corresponding clock is gated
0x1 = Act : Corresponding clock is active
2 CLKACTIVITY_DBGSYS R 0h
This field indicates the state of the Debugss sysclk clock in the
CLK
domain.
0x0 = Inact : Corresponding clock is gated
0x1 = Act : Corresponding clock is active
1-0 CLKTRCTRL R/W 2h
Controls the clock state transition of the L3 AON clock domain.
0x0 = NO_SLEEP : NO_SLEEP: Sleep transition cannot be initiated.
Wakeup transition may however occur.
0x1 = SW_SLEEP : SW_SLEEP: Start a software forced sleep
transition on the domain.
0x2 = SW_WKUP : SW_WKUP: Start a software forced wake-up
transition on the domain.
0x3 = Reserved : Reserved.
