Apply 1.8 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.
Connect a ceramic resonator or a crystal oscillator between
the XIN and XOUT pins
to the XOUT pin and leave the XIN pin open.
These pins are provided for XCIN clock generation circuit I/O.
Connect a crystal oscillator between the XCIN and XCOUT
pins
leave the XCOUT pin open.
INT interrupt input pins.
INT0 is timer RB, and RC input pin.
