Note : 1. During read cycle time, WE is to be "H" level.
2. During write cycle time that is controlled by CS1 or CS2, Output Buffer is in high impedance state, whether OE level is "H" or "L".
3. During write cycle time that is controlled by WE, 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 opposite signals to the I/O terminals.
