G1
Analog-to-digital converter input 1.AnalogIAIN1
UART module 1 Data Carrier Detect modem status input signal.TTLIU1DCD
GPIO port E bit 3.TTLI/OPE3
G2
Analog-to-digital converter input 0.AnalogIAIN0
1-Wire Single Bus Pin. This signal is input only if 1-Wire Alternate
Output is enabled.
TTLI/OOWIRE
UART module 1 Data Terminal Ready modem status input signal.TTLOU1DTR
The ground reference for the analog circuits (ADC, Analog
Comparators, etc.). These are separated from GND to minimize
the electrical noise contained on VDD from affecting the analog
functions.
Power-GNDA
G4
A reference voltage used to specify the input voltage at which the
ADC converts to a minimum value. This pin is used in conjunction
with VREFA+, which specifies the maximum value. In other words,
the voltage that is applied to VREFA- is the voltage with which an
AINn signal is converted to 0, while the voltage that is applied to
VREFA+ is the voltage with which an AINn signal is converted to
4095. The VREFA- voltage is limited to the range specified in Table
32-44 on page 2136.
