Apply 2.2 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 XIN clock generation circuit I/O.
Connect a ceramic resonator or a crystal oscillator between
the XIN and XOUT pins
