Section 21 A/D Converter
21.1.2 Input Pins
Table 21.1 summarizes the A/D converter's input pins. The eight analog input pins are divided into
two groups: A/D0 (AN0 to AN3), and A/D1 (AN4 to AN7). AV_CC and AV_SS are the power supply
inputs for the analog circuits in the A/D converter. AV_CC also functions as the A/D converter
reference voltage pin. AV_SS also functions as the A/D converter reference ground pin.
