17.2 Input/Output Pins
Table 17.1 shows the pin configuration of the A/D converter.
The AV
CC and AVSS pins are the power supply pins for the analog block in the A/D converter. The
Vref pin is the A/D conversion reference voltage pin.
The sixteen analog input pins are divided into two channel sets: channel set 0 (AN0 to AN7) and
channel set 1 (AN8 to AN15).
