20.1.3 Input Pins
Table 20.1 summarizes the A/D converter’s input pins. The eight analog input pins are divided
into two groups: group 0 (AN0 to AN3), and group 1 (AN4 to AN7). AV_CC and AV_SS are the
power supply inputs for the analog circuits in the A/D converter. AVcc also functions as the A/D
converter reference voltage pin.
