Description
Power supply
VCC, VSS
I
Applicable as follows: VCC = 3.0 to 5.5 V, VSS = 0 V
Analog power
supply
AVCC, AVSS
I
Power supply for the A/D converter. AVCC and AVSS
should be connected to VCC and VSS, respectively
Connecting pins
for decoupling
capacitor
VDC0, VDC1
—
A decoupling capacitor for internal voltage should be
connected between VDC0 and VDC1
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 crystal, or a
ceramic resonator 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 low
speed clocks, 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
