Section 24 A/D Converter
Table 24.1 shows the pin configuration of the A/D converter.
The AVCC and AVSS pins are the power supply pins for the analog block in the A/D converter.
Unit 1 has 12 analog input pins; unit 2 has four analog input pins. Note that the actual number of
analog inputs in units 1 and 2 depends on the product group.
