NAME
FUNCTION
26
REF1
Reference 1 Input. Reference voltage. Leave unconnected to
use the internal reference (4.096V). REF1 is the positive
reference in ADC external differential reference mode. Bypass
REF1 to AGND with a 0.1F capacitor in external reference
mode only. See the ADC/DAC References section.

REF2/AIN6
Reference 2 Input/Analog Input Channel 6. See Table 5 for
details on programming the setup register. REF2 is the
negative reference in the ADC external differential reference
mode.
36
CNVST/
AIN7
Active-Low Conversion Start Input/Analog Input 7. See Table 5
for details on programming the setup register.
