NOTE:
1. /CE or /WE must be high during address transition.
2. Because I/O may be active (/OE low) during this period, data input signals of opposite
polarity to the outputs must not be applied.
3. If /OE is high, the I/O pins remain in a state of high impedance.
4. Either t_WR1 or t_WR2 must be met.
5. Either t_DH1 or t_DH2 must be met.
