Possible to assert /CS and /WR at the same time? (CFAF240320K-T-TS)

Hi,

we're having some difficulties talking to a CFAF240320K-T-TS using the 16 Bit interface. We're not certain about the root of all evil and one of the questions left open is weather it is legal to assert /CS and /WR with the same signal. We're not reading (so /RD is connected to IOVCC).
According to the timing diagrams we'd figure it's ok to do so - can anyone confirm?

Thanks,
Raphael

Looking at the information between pages 68 and 69, it looks like, for whatever reason, that they want WR to return to the low state prior to CS being low again. I would venture to guess that it'd be iffy to drive CS and WR from the same line -- though I'm not calling the proper authorities to verify the legality of it. :)
