Description
Power Supply Input VCC, VSS
I
Apply 2.7 V 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.
Main Clock Input
XIN
I
These pins are provided for main 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.
Main Clock Output
XOUT

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_3 also function as LED drive ports.
Input Port
P4_2, P4_6, P4_7
I
Input-only ports
