15.1.3 Input Pins
Table 15.1 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 for the analog circuits in the A/D converter. V_REF is the A/D conversion reference voltage.
