Configuration of 8-/10-bit A/D Converter

This section explains the pins, registers, and interrupt factors of the A/D converter.

Pins of 8-/10-bit A/D Converter

The pins of the 8-/10-bit A/D converter serve as general-purpose I/O ports. Table 18.3-1 shows the pin
functions and the setting required for use of the 8-/10-bit A/D converter.
