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.
