32.3.2.3 DAC as Source For Internal Peripherals
The analog output of the DAC is internally connected to both
the AC and the ADC and is available to these peripherals when
the DAC is enabled (ENABLE = ‘1
’ in DAC.CTRLA).
When the DAC analog output is only being used internally, it is
not necessary to enable the pin output driver (i.e., OUTEN =
‘0
’ in DAC.CTRLA is
acceptable).
