Description
Power supply input
VCC, VSS
I
Apply 2.2 to 5.5 V (J, K version are 2.7 to 5.5 V) to the VCC
pin. Apply 0 V to the VSS pin.
Analog power
supply input
AVCC, AVSS
I
Power supply for the A/D converter.
Connect a capacitor between AVCC and AVSS.
Reset input
RESET
I
Input “L” on this pin resets the MCU.
MODE
I
Connect this pin to VCC via a resistor.
XIN clock input
XIN
I
These pins are provided for XIN clock generation circuit I/O.
Connect a ceramic resonator or a crystal oscillator between
the XIN and XOUT pins. To use an external clock, input it to
the XIN pin and leave the XOUT pin open.
XIN clock output
XOUT
O
XCIN clock input
(N, D version)
XCIN
I
These pins are provided for XCIN clock generation circuit I/O.
Connect a crystal oscillator between the XCIN and XCOUT
pins. To use an external clock, input it to the XCIN pin and
leave the XCOUT pin open.
XCIN clock output
(N, D version)
XCOUT
O
INT interrupt input
INT0, INT1, INT3
IINT interrupt input pins
Key input interrupt
KI0 to KI3
I
Key input interrupt input pins

I
Analog input pins to A/D converter
I/O port
P1_0 to P1_7,
P3_3 to P3_5, P3_7,
P4_5
I/O
CMOS I/O ports. Each port has an I/O select direction
register, allowing each pin in the port to be directed for input
or output individually.
Any port set to input can be set to use a pull-up resistor or not
by a program.
P1_0 to P1_7 also function as LED drive ports (N, D version).
Input port
P4_2, P4_6, P4_7
I
Input-only ports
