You would have to use the linker flags to define _CPUClockSpeed as
80000000 when linking your application, but other than that I think
that everything would be o.k.

Make sure that any devices you have hooked to the external bus still
meet the TA* setup time -- the 64 MHz version of the MCF5282 requires
Tsetup to be at least 10ns -- so external devices have only 5.625 ns
from CLK till they have to have TA* asserted. This was a real pain to
deal with in my ColdFire/FPGA applications.

Hello,
Recently the Arcturus company relesed new uC5282 model.

The difference is coldfire CPU clock 80 MHz(previous model clock is
64 MHz).
Model : uC5282-16E16C80-XR
Somebody use this model for embedded m68k-RTEMS IOC applications ?

If i choson this model, all of BSP is compatible in recent m68k-
RTEMS BSP ?

Thanks.
