6.3.3. DDR Mapping Window Control (DRWINEN)
This register enables or disables each DDR Mapping Register. Before enabling any Mapping Window, i.e. Windows #0 to
#3, corresponding registers, i.e. DRWIN00, DRWIN01, DRWIN02, and DRWIN03, has to be preset with precise value.
If failed, the system might cause serious malfunction and result is unknown.
