Input/Output Pins

Table 16.1 summarizes the pins used by the A/D converter. The 6 analog input pins are divided
into two groups consisting of four channels and two channels. Analog input pins 0 to 3 (AN0 to
AN3) comprising group 0 and analog input pins 4 and 5 (AN4 and AN5) comprising group 1. The
AVcc and AVss pins are the power supply pins for the analog block in the A/D converter.
