DDR Data Swizzling 

To achieve better memory performance and timing, Intel Design performed DDR Data 
pin swizzling that allows a better use of the product across different platforms. 
Swizzling has no effect on functional operation and is invisible to the operating 
system/software.

However, during debug, swizzling needs to be taken into consideration. Therefore, this 
swizzling information is presented. When placing a DIMM logic analyzer, the design 
engineer must pay attention to the swizzling table to be able to debug memory 
efficiently.
