Functions

Power

source pins

Input

Power supply pin. Connect this pin to the

system power supply.

Input

Ground pin. Connect this pin to the system

power supply (0V).

Input

Analog power supply pin for the A/D converter.

When the A/D converter is not used, connect

this pin to the system power supply.

Input

See section 20, Power Supply Circuit, for a

typical connection.

Clock pins

OSC1

Input

OSC2/

CLKOUT

Output

These pins connect with crystal or ceramic

resonator for the system clock, or can be used

to input an external clock. When the on-chip

oscillator is used, the system clock can be

output on OSC2 pin.

See section 5, Clock Pulse Generator, for a

typical connection.

Input

Output

These pins connect with a 32.768 kHz crystal

resonator for the subclock. See section 5, Clock

Pulse Generator, for a typical connection.

System

control

RES

Input

Reset pin. The pull-up resistor (typ. 150 k

Ω) is

incorporated. When driven low, this LSI is reset.

TEST

Input

Test pin. Connect this pin to Vss.

Interrupt

pins

NMI

Input

Non-maskable interrupt request input pin. Be

sure to pull up by a resistor.

IRQ0 to

IRQ3

51 to 54

Input

External interrupt request input pins. Can select

the rising or falling edge.

WKP0 to

WKP5

13, 14,

19 to 22

Input

External interrupt request input pins. Can select

the rising or falling edge.

RTC

TMOW

Output

This is an output pin for a divided clock.

Timer B1

TMIB1

Input

External event input pin
