The device low-power states are the result of any valid combination of power domain states in which all the power domains are no longer in ACTIVE state. In such a situation the PRCM module hardware can trigger events to further lower the consumption of the device and the system.
These device low-power states are characterized by the system power consumption, wake-up latency, and required functionality.
The low-power states are:
The VD_RTC remains always ON regardless of the low power state. RTC_SS is the only wake-up event source in the lowest power mode - "RTC mode".
For more details on the wakeup-sources from the "RTC mode" and the "STANDBY" low-power modes, refer to the Table 3-433.
Once the PRCM module hardware detects any valid combination of power domain states, and if a proper programming model of the PRCM module is set, the PRCM module automatically triggers the transition into the device low-power mode.
