3.7.3.2 12-bit DAC Output
The output of the DAC can be placed on an external pin or selected as an input to the
analog comparator or ADC.
3.7.3.3 12-bit DAC Analog Supply and Reference Connections
This device includes dedicated VDDA and VSSA pins.
This device contains separate VREFH and VREFL pins on 48-pin and higher devices.
These pins are internally connected to VDDA and VSSA respectively, on 32-pin devices.
3.7.3.4 12-bit DAC Reference
For this device VREFH and VDDA are selectable as the DAC reference. VREFH is
connected to the DACREF_1 input and VDDA is connected to the DACREF_2 input.
Use DACx_C0[DACRFS] control bit to select between these two options.
Be aware that if the DAC and ADC use the same reference simultaneously, some
degradation of ADC accuracy is to be expected due to DAC switching.
