17.2
Table 17.1 summarizes the pins used by the A/D converter. The eight analog input pins are
divided into two groups consisting of four channels. Analog input pins 0 to 3 (AN0 to AN3)
comprising group 0 and analog input pins 4 to 7 (AN4 to AN7) comprising group1. The AVCC
and AVSS pins are the power supply pins for the analog block in the A/D converter.
