In the documentation for the K60, FB_TS and FB_ALE are shown as indeterminate at the beginning of the cycle. Why is this? I assume there must be a reason why it has been drawn it this way, and I need to understand why in order to design a reliable FlexBus interface.
I have only seen two instances of the diagram being drawn as I expect it should be. In AN4393, Figures 10 and 11 show FB_ALE as I think it should be. Every other diagram I've seen shows the signal as indeterminate at the start of the cycle.
