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 (0 V).

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

Internal step-down power supply pin. Connect

a capacitor of around 0.1

µF between this pin

and the Vss pin for stabilization.

Clock pins

OSC1

Input

OSC2

Output

These pins connect with crystal or ceramic

resonator for the system clock, or can be used

to input an external clock.

See section 5, Clock Pulse Generators, for a

typical connection.

System

control

RES

Input

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

Ω) is

incorporated. When driven low, the chip is

reset.

TEST

Input

Test pin. Connect this pin to Vss.

NMI

Input

Non-maskable interrupt request input pin. Must

be pulled-up with a resistor.

Interrupt

pins

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.

Timer B1

TMIB1

Input

External event input pin.

Timer V

TMOV

Output

This is an output pin for waveforms generated

by the output compare function.

TMCIV

Input

External event input pin.

TMRIV

Input

Counter reset input pin.

TRGV

Input

Counter start trigger input pin.
