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.
Connect a capacitor between AVCC and AVSS.
Input “L” on this pin resets the MCU.
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. 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.
