Input/Output Pins

Table 18.1 shows the pin configuration of the A/D converter.
The AV and AV pins are the power supply pins for the analog block in the A/D converter. The
CC SS
Vref pin is the reference voltage pin for the A/D conversion.
The sixteen analog input pins are divided into two channel sets: channel set 0 (AN0 to AN7) and
channel set 1 (AN8 to AN15).
