8.1.12.8.1 CM_CEFUSE_CLKSTCTRL Register (offset = 0h) [reset = 2h]
CM_CEFUSE_CLKSTCTRL is shown in Figure 8-162 and described in Table 8-176.
This register enables the domain power state transition. It controls the HW supervised domain power state
transition between ON-ACTIVE and ON-INACTIVE states. It also hold one status bit per clock input of the
domain.

Bit Field Type Reset Description
31-10 Reserved R 0h
9 CLKACTIVITY_CUST_EF R 0h This field indicates the state of the Cust_Efuse_SYSCLK clock input
USE_SYS_CLK of the domain.
[warm reset insensitive]
0x0 = Inact : Corresponding clock is definitely gated
0x1 = Act : Corresponding clock is running or gating/ungating
transition is on-going
8 CLKACTIVITY_L4_CEFU R 0h This field indicates the state of the L4_CEFUSE_GCLK clock input of
SE_GICLK the domain.
[warm reset insensitive]
0x0 = Inact : Corresponding clock is definitely gated
0x1 = Act : Corresponding clock is running or gating/ungating
transition is on-going
7-2 Reserved R 0h
1-0 CLKTRCTRL R/W 2h
Controls the clock state transition of the clock domain in customer
efuse power 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.
