A DAC conversion is automatically started when new data to be converted are available. Events from the event
system can also be used to trigger a conversion, and this enables synchronized and timed conversions between the
DAC and other peripherals, such as a timer/counter. The DMA controller can be used to transfer data to the DAC.
The DAC has high drive strength, and is capable of driving both resistive and capacitive loads, aswell as loads which
combine both. A low-power mode is available, which will reduce the drive strength of the output. Internal and external
voltage references can be used. The DAC output is also internally available for use as input to the analog comparator
or ADC.
PORTB has one DAC. Notation of this peripheral is DACB.
