When the MCU domain is active, all AUX modules are both accessible with minimum latency and functional to an MCU master, independent of the AUX clock and power management. Hence, the System CPU application has no need to configure the AUX operational mode to use a peripheral. The System CPU application cannot use an AUX peripheral in standby TI-RTOS power mode, except for wakeup. The Sensor Controller Engine can however run when the rest of the system is in Standby, and can thus be used to minimize current consumption.
TI-RTOS requests the Power-Down operational mode by default.
