I/O
Description
Power supply
VCC, VSS
I
Applicable as follows: VCC = 3.0 to 5.5 V, VSS = 0 V
Connecting pins
for decoupling
capacitor
VDC0, VDC1
—
A decoupling capacitor for internal voltage should be
connected between VDC0 and VDC1
Analog power
supply
AVCC, AVSS
I
Power supply for the A/D converter. AVSS should be
connected to VSS
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 a debugger. It should
be connected to VCC via a resistor of 1 to 4.7 k
Ω
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 INT5
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
P0_0 to P0_7
P1_0 to P1_7
P2_0 to P2_7
P3_0 to P3_7
P4_0 to P4_7
P5_0 to P5_7
P6_0 to P6_7
P7_0 to P7_7
P8_0 to P8_4,
P8_6, P8_7
P9_3 to P9_7
P10_0 to P10_7
I/O
I/O ports in CMOS. Each port can be programmed to
input or output under the control of the direction
register.
Pull-up resistors are selected for following 4-pin
units, but are enabled only for the input pins: Pi_0 to
Pi_3 and Pi_4 to Pi_7 (i = 0 to 10)
Input port
P9_1
I
Input port in CMOS. Pull-up resistors are selected for
P9_1 and P9_3
