15.2
Table 15.1 summarizes the input pins used by the A/D converter. 16 analog input pins are divided
into four groups, each of which includes four channels; analog input pins 0 to 3 (AN0 to AN3)
comprising group 0, analog input pins 4 to 7 (AN4 to AN7) comprising group 1, analog input pins
8 to 11 (AN8 to AN11) comprising group 2, and analog input pins 12 to 15 (AN12 to AN15)
comprising group 3. The AVcc and AVss pins are the power supply pins for the A/D converter
analog section. The Vref pin is the A/D conversion reference voltage pin.
