Address (Input)
CS (Input)
WE (Input)
I/O (Input/Output)
Cautions 1. CS or WE should be fixed to high level during address transition.
2. When I/O pins are in the output state, do not apply to the I/O pins signals that are opposite
in phase with output signals.
Remarks 1.
Write operation is done during the overlap time of a low level CS and a low level WE.
2.
When WE is at low level, the I/O pins are always high impedance. When WE is at high level,
read operation is executed. Therefore OE should be at high level to make the I/O pins high
impedance.
3.
If CS changes to low level at the same time or after the change of WE to low level, the I/O pins
will remain high impedance state.
