EMIF_RnW timing

I am looking for timing information of the TMS EMIF_RnW pin when the EMIF is configured in the Select Strobe Mode.  Does it stay low for the complete write transaction or have the same duration as CS?

    EMIF_RnW has the same timing as an address line - here by timing I mean at the protocol level (setup, hold, strobe).

    It's valid after the start of the setup period and held until the end of the strobe peirod.

    That much said we don't have any timing parameter or other documentation that describes the RnW signal.  So you should not design a system using if you need to know how it behaves.
