39.6.6 Sleep Mode Operation

The generic clock for the DAC is running in idle sleep mode. If the Run In Standby bit in the Control A register (CTRLA.RUNSTDBY) is one, the DAC output buffer will keep its value in standby sleep mode. If CTRLA.RUNSTDBY is zero, the DAC output buffer will be disabled in standby sleep mode. Additionally, when the CTRLA.RUNTDBY is '0', upon exiting from STANDBY, the empty interrupt flag (INTFLAG.EMPTY) will be set if a conversion was ongoing at STANDBY entry. This can be ignored and cleared when necessary.
