NAME
FUNCTION
22
RES_SEL
Reset Select. Selects DAC wake-up mode. Set RES_SEL low
to wake up the DAC outputs with a 100k
Ω resistor to GND or
set RES_SEL high to wake up the DAC outputs with a 100k
Ω
resistor to VREF. Set RES_SEL high to power up the DAC input
register to FFFh. Set RES_SEL low to power up the DAC input
register to 000h.
26
REF1
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 0.1F capacitor in external reference mode only.
See the ADC/DAC References section.
