DQ15/A-1
) A9 y* A* B$ Q$ @% O: q, }8 zWhen BYTE# is HIGH, this pin behaves as a data I/O pin, DQ[14:8]. When BYTE# is LOW, this pin behaves as an address pin; DQ15/A-1 LOW selects the LSB of the word on the other addresses, DQ15/A-1 HIGH selects the MSB. Throughout the text, consider references to data I/O to include this pin when BYTE# is HIGH and consider references to address inputs to include this pin when BYTE# is LOW, except when stated explicitly otherwise.
