PL330 data element transfer size

Hello,

 

Is there a was to have the PL330 move one data element (8-bit, 16-bit, 32-bit) per transfer as shown in "A" in attached?

What I see is more like "B".

 

For example, if I was moving 16-bit data ove a 32-bit AXI interface, I would want only one 16-bit value to be sent per transfer (as in A), but what I see is two 16-bit values in one 32-bit transfer (as in B).

 

For 8-bit values I see four per transfer.

 

I understand that "B" is more efficient, but the RTL in the PL I am doing would really like to data moved as in "A"

 

Thanks
