Function

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 µF).

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 XIN and XOUT pins. To use

an externally derived clock, input it to the XIN pin and

leave the XOUT pin open.

Transfer clock I/O pin.

Serial data input pins.

Serial data output pins.

Reference voltage input pin for A/D converter. Con-

nect the VREF pin to Vcc.

Analog input pins for A/D converter

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.

P10 to P17 also function as LED drive ports.

Port for input-only.
