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 t
WR1
or t
WR2
must be met.
5.
Either t
DH1
or t
DH2
must be met.
