DAC: Digital-to-analog Converter
Each channel can be enabled or disabled independently, and has its own data register. The
ADC can be configured to automatically enter Sleep mode after a conversion sequence, and can
be triggered by the software, the Timer Counter, or an external signal.
Each DAC has an analog output pin, DA0 and DA1, and provides an interrupt signal to the AIC
DA0IRQ and DA1IRQ. Both DACs share the analog power supply pins VDDA and GNDA, and
the input reference DAVREF.
