10 | CLKACTIVITY_RTC_AUX_CLK | This field indicates the state of the RTC_AUX_CLK in the domain. [warm reset insensitive] | R | 0x0 |
0x0: Corresponding clock is definitely gated | ||||
0x1: Corresponding clock is running or gating/ungating transition is on-going | ||||
9 | RESERVED | R | 0x0 | |
8 | CLKACTIVITY_RTC_L4_GICLK | This field indicates the state of the RTC_L4_GICLK clock in the domain. [warm reset insensitive] | R | 0x0 |
0x0: Corresponding clock is definitely gated | ||||
0x1: Corresponding clock is running or gating/ungating transition is on-going | ||||
7:2 | RESERVED | R | 0x0 | |
1:0 | CLKTRCTRL | Controls the clock state transition of the WKUPAON clock domain. | RW | 0x0 |
0x0: NO_SLEEP: Sleep transition cannot be initiated. Wakeup transition may however occur. | ||||
0x1: Reserved | ||||
0x2: SW_WKUP: Start a software forced wake-up transition on the domain. | ||||
0x3: HW_AUTO: Automatic transition is enabled. Sleep and wakeup transition are based upon hardware conditions. |

17:16 | IDLEST | Module idle status. [warm reset insensitive] | R | 0x3 |
0x0: Module is fully functional, including OCP | ||||
0x1: Module is performing transition: wakeup, or sleep, or sleep abortion | ||||
0x2: Module is in Idle mode (only OCP part). It is functional if using separate functional clock | ||||
0x3: Module is disabled and cannot be accessed | ||||
15:2 | RESERVED | R | 0x0 | |
1:0 | MODULEMODE | Control the way mandatory clocks are managed. | RW | 0x0 |
0x0: Module is disabled by SW. Any OCP access to module results in an error, except if resulting from a module wakeup (asynchronous wakeup). | ||||
0x1: Reserved | ||||
0x2: Module is explicitly enabled. Interface clock (if not used for functions) may be gated according to the clock domain state. Functional clocks are guarantied to stay present. As long as in this configuration, power domain sleep transition cannot happen. | ||||
