Unbuffered Output as Source For Internal Peripherals

The unbuffered analog output of the DAC can be used as a source for internal peripherals when the ENABLE bit in the Control A (DACn.CTRLA) register is ‘1’.

When using only the unbuffered analog output of the DAC, the Output Buffer Enable (OUTEN) bit in DACn.CTRLA can be ‘0’, freeing the DAC output pin to be used by other peripherals.
