4.6.3 Managing the Sensor Controller and the Auxiliary Domain Power

The sensor controller power management is independent of the system power modes in Section 3. The Cortex-M3 can force on the auxiliary domain (which contains the sensor controller) to access modules in the auxiliary domain or the oscillators.

The sensor controller is either active or standby where it executes code or waits for events. When the sensor controller is standing by, it can wake up and execute code and re-enter standby independently of the system state excluding shutdown. The sensor controller may take the rest of the system out of either idle or standby by configuring AON_EVENT:MCUWUSEL[29:24] to use the AUX_SWEV1. When the system state is shutdown, the sensor controller is unavailable. The sensor controller studio software uses AON_EVENT:AUXWUSEL[5:0] to wake up the sensor controller from standby using the RTC_CH2_DLY event.

NOTE

The sensor controller interface driver handles these events.
