Pins of 10-bit A/D Converter

This section describes the pins of the 10-bit A/D converter.
Pins of 10-bit A/D Converter
This series has 8 channels of analog input pin.
Analog input pins also serve as general-purpose I/O ports.
AN07 to AN00 Pin
AN07 to AN00: When using the A/D conversion function, input the analog voltage you wish to convert
Note that the number of analog input pins differs depending on the series.

to one of these pins. Each of the pins serves as an analog input pin by selecting it using
the analog input channel select bits (ADC1: ANS0 to ANS3) with the corresponding bit
in the port direction register (DDR) set to 0. Even when the 10-bit A/D converter is used,
the pins not used for analog input can be used as general-purpose I/O ports.
This is a pin used to activate A/D conversion function by external trigger.
This also can be used as 10-bit A/D converter power supply pin and inputs the reference
voltage of the 10-bit A/D converter.
This also can be used as a ground pin of the 10-bit A/D converter.
