FlexBus burst mode question

Hi, I've looked over the reference manual and have a couple of questions about the FlexBus.

 

The only bus timings I see appear to show that all Flexbus signals must be qualified with the FB_CLK.  Please confirm, Flexbus is not an asynchronous bus.

 

There are diagrams of 32 bit to 8 bit port burst (looks like 6 clocks min).  But, I'm interested in doing a 32 bit to 16 bit port bursts.  If I do 32 to 16, how many clock cycles is the access?  4?  5?

 

I was really hoping to burst several 32 bit words per cycles, but I don't see that listed.   I'm assumming that idea is not possible.

 

Thanks,

 

John Fielden
