Section 28 A/D Converter
28.1.3 Input Pins
Table 28.1 summarizes the A/D converter’s input pins. The six analog input pins are divided into
two groups: group 0 (AN2 , AN3), and group 1 (AN4 to AN7). AV_CC and AV_SS are the power
supply for the analog circuits in the A/D converter. AVcc also functions as the A/D converter
reference voltage.
