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

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 to a crystal or

ceramic resonator for system

clocks, 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.

Interrupt

pins

NMI

Input

Non-maskable interrupt request

input pin. Be sure to pull-up by a

pull-up resistor.
