39.5.1 Initialization

The following steps are necessary to operate the DAC:

• The reference voltage fixed to VDDA.
• Configure the usage of the DAC output:
  • Configure an internal peripheral to use the DAC output. Refer to the documentation of the respective peripherals.
  • Enable the output to a pin by writing a ‘1’ to the Output Buffer Enable (OUTEN) bit. The Port peripheral needs to disable the input for the DAC pin.
• Write an initial digital value to the Data (DACCODE.DATA) register.
• Enable the DAC by writing a ‘1’ to the ENABLE bit in the Control A (DACCON.EN) register.
