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.
