Apply 2.7 V to 5.5 V to the Vcc pin. Apply 0 V to the
Vss pin.
This pin is to stabilize internal power supply.
Connect this pin to Vss via a capacitor (0.1 F).
Do not connect to Vcc.
Power supply input pins for A/D converter. Connect the
AVcc pin to Vcc. Connect the AVss pin to Vss. Connect a
capacitor between pins AVcc and AVss.
Input “L” on this pin resets the MCU.
Connect this pin to Vss via a resistor.
Connect this pin to Vcc via a resistor.
These pins are provided for the main clock generat-
ing circuit I/O. Connect a ceramic resonator or a crys-
tal oscillator between the X

These are 8-bit CMOS I/O ports. Each port has an I/O
select direction register, allowing each pin in that port
to be directed for input or output individually.
Any port set to input can select whether to use a pull-
up resistor or not by program.
