That is correct Davide. the reason for that is that in Control mode, one
of the A/B halfs cannot be written, in short we only get 16 bits of
contiguous data in memory.

The neagitve part of using only Object mode is that Of the programming
regions/sector, we loose one complete region for the cleanmarker..
something like 128K(? dont remember off hand) for 8/12 bytes of
cleanmarker/EBH and hence the implementation using write buffering
(something we do on nand-like flash devices) on M18 flashes.
