43. Digital-to-Analog Converter Controller (DACC)
43.1 Description
The Digital-to-Analog Converter Controller (DACC) provides 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.
