Input/Output Pins

Table 15.1 summarizes the input pins used by the A/D converter. The AN0 to AN3 and AN14 to

AN15 pins are analog input pins. The VCC and VSS pins are the power supply pins for the

analog block in the A/D converter. The Vref pin is the reference voltage pin for the A/D

conversion.
