Section 18 A/D Converter
18.2
Input/Output Pins
Table 18.1 summarizes the input pins used by the A/D converter. The 8 analog input pins are
divided into two groups; analog input pins 0 to 3 (AN0 to AN3) comprising group 0, analog input
pins 4 to 7 (AN4 to AN7) comprising group 1. The AVcc pin is the power supply pin for the
analog block in the A/D converter.
