31.3.2.2 Starting a Conversion

When the DAC is enabled (ENABLE = ‘1’ in DACn.CTRLA), a conversion starts as soon as the Data (DACn.DATA) register is written.

When the DAC is disabled (ENABLE = ‘0’ in DACn.CTRLA), writing to the DACn.DATA register does not trigger a conversion. Instead, the conversion starts on writing a ‘1’ to the ENABLE bit in the DACn.CTRLA register.
