Apply 2.7V to 5.5V to the VCC pin. Apply 0V to
the VSS pin
Power supply input pins to A/D converter.
Connect AVCC to VCC. Apply 0V to AVSS.
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 main 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.

Any port set to input can select whether to use a
pull-up resistor or not by program.
P1_0 to P1_3 also function as LED drive ports.
