-
- It depends on the memory system, on my Warp Engine with 4-2-2-2
- memory subsystem, it is faster to have data burst on even
- when accessing FAST-ram randomly. I guess that is because
- the data cache will be switched off too when data burst
- is off, and so will copyback.
-
- On the 68040 data burst cant be switched off without turning
- the data cache and thus copyback off, too.
