A/D converter reference voltage (high potential side)
Be sure to turn on/off this pin with potential higher than AVRH applied to
VCC.
A/D converter reference voltage (low potential side)
VSS pin for A/D converter.
A/D converter analog input
These pins are enabled when the AIC register is designated for analog
N input.
These pins are available as ports when A/D converter analog input is not
in use.

Earth level (VSS) for digital circuit
Always power supply pin (VSS) must be connected to the power supply.
Note : On the majority of pins listed above, the I/O port and the resource I/O are multiplexed, such as XXXX/Pxx.
When the port and the resource output compete against each other on these pins, priority is given to the
resource.
