The Digital-to-Analog Converter Controller (DACC) offers up to 2 analog outputs, making it possible for the digital-to-
analog conversion to drive up to 2 independent analog lines. 

The DACC supports 12-bit resolution. Data to be converted are sent in a common register for all channels. External
triggers or free running mode are configurable.

The DACC integrates a Sleep Mode and connects with a PDC channel. These features reduce both power consumption
and processor intervention.

The user can configure DACC timings, such as Startup Time and Refresh Period.
