I/O Function
—
Apply the power supply voltage to this pin.
—
Connect to ground.
Input Not for use by the user application. Connect to GND
potential.
Input Used to reset the MCU.
Input Internal oscillator input/output pins. Connect a ceramic
resonator, crystal resonator, or external oscillator circuit.
Output When using CR oscillation, connect a resistor.
I/O
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 I/O pins, addressed in 4-bit units.
Input External interrupt input pin
Input Input pin used for transition from stop mode to active
mode.
I/O Serial interface clock I/O pin
Input Serial interface receive data input pin
Output Serial interface transmit data output pin
Output Timer output pins
Input Event count input pin
—
