Reference DAC usage requires application ownership. For semaphore allocation in TI software, see Section 20.4.3.3.
Sensor Controller Studio provides the required API to use the Reference DAC, and The Sensor Controller can use the peripheral in all AUX operational modes.
The System CPU can use the peripheral in TI-RTOS power modes Active and Idle. In this case, set AUX_SYSIF:PEROPRATE.ANAIF_DAC_OP_RATE to BUS_RATE.
The System CPU can use the peripheral in Standby TI-RTOS power mode if the Sensor Controller is not used by the application. In this case, the System CPU must set AON_PMCTL.AUXSCECLK.PD_SRC to SCLK_LF and switch between Low-Power and Power-Down operational modes. The following sequence is required:
