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 k
to 100 k
.
The reset input pin.
Connect a ceramic resonator between the X
IN
and X
OUT
pins, or input an external
clock from the X
IN
pin with the X
OUT
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.
