Function
Applies power voltage
Connected to ground
Cannot be used in user applications. Connect this pin
to GND.
Resets the MCU
Input/output pin for the internal oscillator. Connect
these pins to the ceramic oscillator or crystal oscillator,
or OSC₁ to an external oscillator circuit.
Input/output pins addressed individually by bits; D₀–D₈
are all standard-voltage I/O pins.
One-bit standard-voltage input port pin
Four-bit input/output pins consisting of standard-voltage
pins
Four-bit input/output pins consisting of intermediate
voltage pins
Input pins for external interrupts
Input pin for transition from stop mode to active mode
Serial interface clock input/output pin
Serial interface receive data input pin
Serial interface transmit data output pin
Timer output pin
Event count input pin
Square waveform output pin
Power supply for the A/D converter. Connect this pin
as close as possible to the V_CC pin and at the same
voltage as V_CC. If the power supply voltage to be used
for the A/D converter is not equal to V_CC, connect a 0.1-
µF bypass capacitor between the AV_CC and AV_SS pins.
(However, this is not necessary when the AV_CC pin is
directly connected to the V_CC pin.)
Ground for the A/D converter. Connect this pin as
close as possible to GND at the same voltage as GND.
