15:4 prefetch_burst_length
If prefetch_en is set and prefetch_burst_length is set to ZERO, the controller will
                  start prefetching data only after the receiving the first Map01 read command for the page.
                  If prefetch_en is set and prefetch_burst_length is set to a non-ZERO, valid value, 
                  the controller will start prefetching data corresponding to this value even before 
                  the first Map01 for the current page has been received.
                  The value written here should be in bytes.
