Function
Apply the power supply voltage to this pin.
Connect to ground.
Not for use by the user application. Connect to GND potential.
Used to reset the MCU.
Internal oscillator input/output pins. Connect a ceramic resonator,
crystal resonator, or external oscillator circuit.
When using CR oscillation, connect a resistor.
I/O pins addressed bit by bit. D₀ to D₃ are large-current source
pins (max. 10 mA), and D₄ to D₉ are large-current sink pins (max.
15 mA).
I/O pins, addressed in 4-bit units.

A/D converter power supply pin. Connect as close as possible to
the V_CC pin so as to be at the same potential as V_CC.
Ground pin for AV_CC. Connect as close as possible to the GND pin
so as to be at the same potential as GND.
