21.2
Table 21.1 summarizes the pins used by the A/D converter. The 8 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 group 1. Expanded A/D
conversion input pins (CIN0 to CIN15) can be selected with the AN6 and AN7 pins. The AVcc
and AVss pins are the power supply pins for the analog block in the A/D converter.
