Output Enable (OE) signal behavior
Is OE# an asynchronous or synchronous input?
The OE# signal is one of two asynchronous inputs (MRST# being the other) in Cypress synchronous dual-ports. This means that a rising or falling edge of OE# will trigger a change in the data bus. tOLZ after OE# goes low, the data bus will enter a low-Z state. tOHZ after OE# goes high, the data bus will enter a high-Z state.
