I'm searching a detailed flexbus timing for the K10...K60/ 100 mask. I'm e.g. missing hold time ALE Low to Address valid and also Data valid from CS going high. Where can I find it? The EZPORT timing is given much better within the family datasheets.
Now I know why I even did not get any aswer from freescale. I've done some measurements by myself and found that the adress hold time from ALE going Low is 0 or even little bit negative. That mean that you must use one additional waitstate for ALE for multiplexed flexbus write acces which is a very bad situation and totally waste of performance. With a very fast RAM you waste about 30% of flexbus throughput. I just wonder if the same problem exists on other Cortex M3 devices from other brands.
