8.1.12.6.2 CM_RTC_CLKSTCTRL Register (offset = 4h) [reset = 102h]
CM_RTC_CLKSTCTRL is shown in Figure 8-156 and described in Table 8-168.
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.

9 CLKACTIVITY_RTC_32K R 0h
This field indicates the state of the 32K RTC clock in the domain.
CLK
0x0 = Inact
0x1 = Act
8 CLKACTIVITY_L4_RTC_ R 1h
This field indicates the state of the L4 RTC clock in the domain.
GCLK
0x0 = Inact : Corresponding clock is gated
0x1 = Act : Corresponding clock is active
7-2 Reserved R 0h
1-0 CLKTRCTRL R/W 2h
Controls the clock state transition of the RTC clock domains.
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.
