Write Cycle No. 1 (WE-Controlled)
1,2,3
Write Cycle No. 2 (CS-Controlled)
1,2,3,4,5
Notes:
1.
CS 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 tWR1 or tWR2 must be met.
5.
Either tDH1 or tDH2 must be met.
