Apply 2.7 V 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.
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.

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.
