1 During read cycle time, WE is to be "H" level.
6
2 During write cycle time that is controlled by CS1 or CS2, Input/output Buffer is in high impedance state whether OE level is "H"or
"L".
6
3 During write cycle time that is controlled by WE, Input/output Buffer is high impedance state if OE is "H" level.

4 When I/O terminals are output mode, be careful that do not give the epposite signals to the I/O terminals.
