Power, Reset, and Clock Management
8.1.12.8.1 CM_CEFUSE_CLKSTCTRL Register (offset = 0h) [reset = 2h]
CM_CEFUSE_CLKSTCTRL is shown in
and described in
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.

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

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.
