14.1.3 Pin Configuration
Table 14-1 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).
