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.
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.
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.
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.

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-only ports
These pins are provided for XIN clock generation circuit I/O.
