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 0.1µF capacitor in external reference
mode only. See the ADC/DAC References section.
Analog Inputs
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.
Active-Low Conversion Start Input/Analog Input 7. See Table 5
for details on programming the setup register.
General-Purpose I/O A0, A1. GPIOA0, GPIOA1 can sink and
source 15mA.
General-Purpose I/O C0, C1. GPIOC0, GPIOC1 can sink 4mA
and source 2mA.
Analog Inputs
Reference 2 Input. See Table 5 for details on programming the
setup register. REF2 is the negative reference in the ADC
external differential reference mode.
Active-Low Conversion Start Input. See Table 5 details on
programming the setup register.
Exposed Paddle. Must be externally connected to AGND. Do
not use as a ground connect.
