Power
source pins
V
CC
12 10 Input Power supply pin. Connect this pin
to the system power supply.
V
SS
9 7 Input Ground pin. Connect this pin to the
system power supply (0V).
AV
CC
3 1 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.
V
CL
6 4 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 11 9 Input
OSC2 10 8 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 7 5 Input Reset pin. When this driven low,
the chip is reset.
TEST 8 6 Input Test pin. Connect this pin to Vss.
Interrupt
pins
NMI 35 25 Input Non-maskable interrupt request
input pin. Be sure to pull-up by a
pull-up resistor.

pins. Can select the rising or falling
edge.
WKP0 to
WKP5
13, 14,
19 to 22
11 to 16 Input External interrupt request input
pins. Can select the rising or falling
edge.
