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 (0V).
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 See section 20, Power Supply Circuit, for a
typical connection.
Clock pins OSC1 11 Input
OSC2/
CLKOUT
10 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.
X1 5 Input
X2 4 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 7 Input Reset pin. The pull-up resistor (typ. 150 k) is
incorporated. When driven low, this LSI is reset.
TEST 8 Input Test pin. Connect this pin to Vss.
Interrupt
pins
NMI 35 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 23 Output This is an output pin for a divided clock.
Timer B1 TMIB1 52 Input External event input pin
