Reset Select. Selects DAC wake-up mode. Set RES_SEL low
to wake up the DAC outputs with a 100kΩ resistor to GND or
set RES_SEL high to wake up the DAC outputs with a 100kΩ
resistor to V
register to FFFh. Set RES_SEL low to power up the DAC input
register to 000h.
Reference 1 Input. Reference voltage. Leave unconnected to
use the internal 4.096V reference, REF1 is the positive
reference in ADC external differential mode. Bypass REF1 to
AGND with a 0.1µF capacitor in external reference mode only.
See the ADC/DAC References section.
