Function
Power supply
VCC, VCC0, VSS
I
Applicable as follows: VCC = 4.2 V to 5.5 V, VCC0 =
3.0 V to 3.6 V, VSS = 0 V
Connecting pins
for decoupling
capacitor
VDC0, VDC1
—
A decoupling capacitor for internal logic voltage regu-
lator should be connected between VDC0 and VDC1
Analog power
supply
AVCC, AVSS
I
Power supply for the A/D converter. AVCC and AVSS
should be connected to VCC and VSS, respectively
Reset input
RESET
I
The MCU is reset when this pin is driven low
CNVSS
I
This pin should be connected to VSS via a resistor
Debug port
NSD
I/O
This pin is to communicate with debugger. It should
be connected to VCC via a resistor of 1 to 4.7 k
Main clock input
XIN
I
Input/output for the main clock oscillator. A ceramic
resonator or a crystal oscillator should be connected
between pins XIN and XOUT. An external clock
should be input at the XIN while leaving the XOUT
open
Main clock output XOUT
O
Sub clock input
XCIN
I
Input/output for the sub clock oscillator. A crystal
oscillator should be connected between pins XCIN
and XCOUT. An external clock should be input at the
XCIN while leaving the XCOUT open
Sub clock output
XCOUT
O
Clock output
CLKOUT
O
Output of the clock with the same frequency as fC,
f8, or f32
External interrupt
input
INT0 to INT8
I
Input for external interrupts
NMI input
P8_5/
NMI
I
Input for NMI
Key input interrupt
KI0 to KI3
I
Input for the key input interrupt
I/O ports

P12_0 to P12_7
P13_0 to P13_7
P14_3 to P14_6
P15_0 to P15_7
I/O
I/O ports in CMOS. Each port can be programmed to
input or output under the control of the direction reg-
ister.
A pull-up resistor is selectable for following 4 units of
input ports: Pi_0 to Pi_3 and Pi_4 to Pi_7 (i = 0 to 15)
