44.6.8 Sleep Mode Operation
If the Run In Standby bit in the DAC Control x register DACCCTRLx.RUNSTDBY = 1, the DACx will continue the conversions in Standby Sleep mode.
If DACCCTRLx.RUNSTDBY = 0, the DACx will stop conversions in Standby Sleep mode.
If DACx conversion is stopped in Standby Sleep mode, DACx is also disabled to reduce power consumption. When exiting Standby Sleep mode, DACx is enabled again, therefore a certain startup time is required before starting a new conversion.
DAC Controller is compatible with SleepWalking: if RUNSTDBY = 1, when an input event (STARTx) is detected in Sleep mode, the DAC Controller will request GCLK_DAC in order to complete the conversion.
