Apply 2.7 V to 5.5 V to the VCC pin. Apply 0 V to the
VSS pin.
Applies the power supply for the A/D converter. Connect
a capacitor between AVCC and AVSS.
Input “L” on this pin resets the MCU.
Connect this pin to VCC via a resistor.
These pins are provided for the XIN clock generation
circuit I/O. Connect a ceramic resonator or a crystal
oscillator between the XIN and XOUT pins. To use an
externally derived clock, input it to the XIN pin and leave
the XOUT pin open.
INT interrupt input pins.
INT0 Timer RD input pins.
INT1 Timer RA input pins.
Key input interrupt input pins.
Timer RA I/O pin.
Timer RA output pin.
Timer RB output pin.
Timer RD I/O ports.
External clock input pin.

CAN data input pin.
CAN data output pin.
Reference voltage input pin to A/D converter.
Analog input pins to A/D converter.
CMOS I/O ports. Each port contains an input/output
select direction register, allowing each pin in that port to
be directed for input or output individually.
Any port set to input can select whether to use a pull-up
resistor or not by a program.
Input only ports.
