Functions
Apply 5 V ± 0.5 V to Vcc, and 0 V to Vss.
Connect this pin to Vss.
Connect this pin to Vss via a resistor of 10 kΩ to 100 kΩ.
The reset input pin.
Connect a ceramic resonator between the XIN and XOUT pins, or input an external
clock from the XIN pin with the XOUT pin left open.
Connect this pin to Vcc or Vss. (This is not used in the flash memory serial I/O mode.)
Connect this pin to the filter circuit, or leave this pin open. (This is not used in the flash memory serial I/O mode.)
Connect AVcc to Vcc, and AVss to Vss.
Input an arbitrary level within the range of VSS–VCC. (This is not used in the flash memory serial I/O mode.)
Input “H” or “L”, or leave them open. (This is not used in the flash memory serial I/O mode.)
Input “H” or “L”, or leave them open. (This is not used in the flash memory serial I/O mode.)
Input “H” or “L”, or leave them open. (This is not used in the flash memory serial I/O mode.)
Input “H” or “L”, or leave them open. (This is not used in the flash memory serial I/O mode.)
