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.
Realtime clock oscillator input/output pins.
Connect a 32.768 kHz crystal. If 32.768
kHz crystal oscillation is not used, fix the
X1 pin to VCC and leave the X2 pin open.
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.
External interrupt input pin
Input pin used for transition from stop
mode to active mode.
Serial interface clock I/O pin
Serial interface receive data input pin
Serial interface transmit data output pin
Timer output pins
Event count input pin
A/D converter power supply pin. Connect
as close as possible to the VCC pin so as to
be at the same potential as VCC.
Ground pin for AVCC. Connect as close as
possible to the GND pin so as to be at the
same potential as GND.
A/D converter analog input pins
Connect to GND potential.
