Section 16 A/D Converter (8 Analog Input Channel Version)
16.1.3 Pin Configuration
Table 16.1 summarizes the input pins used by the A/D converter.
The AV_CC and AV_SS pins are the power supply pins for the analog block in the A/D converter. The
V_ref pin is the A/D conversion reference voltage pin.
The eight analog input pins are divided into two groups: group 0 (AN0 to AN3), and group 1
(AN4 to AN7).
