– No Connect: These signals are not internally connected and may be
connected to ground to improve package heat dissipation.
Pin 9B is reserved for address pin expansion; 16MB.
NF
— No Function: These pins are internally connected to the die and
have the capacitance of an input pin. It is allowable to leave
these pins unconnected or driven by signals.
