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
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.
