Power
source pins
V
CC
12 Input Power supply pin. Connect this pin to the
system power supply.
V
SS
9 Input Ground pin. Connect this pin to the system
power supply (0 V).
AV
CC
3 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 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 Input
OSC2 10 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 7 Input Reset pin. The pull-up resistor (typ. 150 kΩ) is
incorporated. When driven low, the chip is
reset.
TEST 8 Input Test pin. Connect this pin to Vss.
NMI 35 Input Non-maskable interrupt request input pin. Must
be pulled-up with a resistor.

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 52 Input External event input pin.
Timer V TMOV 30 Output This is an output pin for waveforms generated
by the output compare function.
TMCIV 29 Input External event input pin.
TMRIV 28 Input Counter reset input pin.
TRGV 54 Input Counter start trigger input pin.
