I have a problem with interfacing a dualuart ic (EXAR XR68C192) with the MCF5280.
The dualuart requires a minimum time of 100ns between to asserted chip selects.

I´ve found the option to insert wait states (chip select control register),
but this leads only to a longer chip select assert time but not a longer deassert time.

How can I extend the chip select deasert time?
