BHE = VIL : 8-bit (D7 to D0)
Note : 1. A-1 is least significant address.
When BHE is 'low', D14 to D8 goes the high impedance state, and D15 should be A-1.

Notes : 1. CE and OE are enable, A17 to A0 are valid.
2. D15/A-1 pin is in the output state when BHE is high, CE and OE are enable.
Therefore, the input signals of opposite phase to the output must not be applied to them.
