In flexbus, how many seconds (Minimum) is time from the rise of CLK signal to a rise of control signal (FB_CS,FB_OE)?
About the time from CLK_RISE to FB_CS(FB_OE)_RISE, is it bigger than a demand value of the hold time for data(datasheet Figure 17 "FB5") ?
Since the device mentioned is MK20FN1M0VLQ12, I am afraid you will have to move this request to the "Kinetis" space (https://community.freescale.com/community/kinetis). This one is only dedicated to the "Vybrid" series (as far as I remember, there should be such an option in upper right corner of the original message web page).
Plus, just a support person's recommendation - it really helps and expedites the process when a relevant chapter / table / diagram / etc. in our documentation is mentioned in the request.
